As I can't seem to post in the orignal thread [ http://nsxcb.co.uk/testvb/showthread.php?t=4978 ] I'm starting a new thread!

Paul do we have any news on these yet?

Paul.

This will be bacause its in a for sale section that requires moderator approval (I think)

Anyway, with the recent d**i debate I pm'd Brian earlier this week and suggested that we were getting nervous about the time its taking to recieve these. This is the response I recieved on Weds eve

I have to get a box for them and I will ship them out. I saw the dali thread and I understand their concern. I am definitely not Dali. It has taken forever and I haven't forgotten you guys. I've been in the process of moving so its difficult to do everything. I promise to give u a final shipping date by the end of this week once I get settled into my new location. Please let them know Im grateful for their patience. If it lags even longer I will ship them individually if I have to to get them all out to you guys. Thanks again Paul!

Brian

In addition I have been in touch with a few Primers I know and they all vouch for Brian but do admit that he can be slow as usually takes on too much work. However they did all say that workmanship is top grade, so sounds as though the wait will have been worth it.

regards, Paul

Since the introduction of the Marketplace system, it is not used as a forum anymore. So posts made to it won't show.

Maybe we will have a group buy section instead, if we are ever brave enough to do them again.

There is another VMax event in a couple of months, so it will be great to have the extra horses by then. Not sure if our cars will break noise laws with them fitted.

Sorry, I've been trying to catch up with work here. It's leaving today. Let the guys know I'm paying for shipping and shipping 2 sets in each box to cut down overall cost. I'll get you the shipping info no later then tomorrow!!

Hi Paul

Paul.

Paul and All,

I had this from Brain overnight ....

I had problems with my logistics guy cause he was charging more then what he promised me. I had to pick up the cats from him to just ship it USPS. I will hit you up tomorrow with a tracking #. It's been terrible trying to get these cats to you. I'll be sending 2 sets in each box at a time. I will give you more info tomorrow. I promise!
Brian

So I hope to have more news before the week is out.

Nathan, these are high flow cats to compliment the various header/zorst combo's as well as reducing rear end weight :)

There is potentially a spare set for a 3.2 subject to the sale of a particular NSX. If you have 02 headers they may well fit?

regards, Paul

08-04-2009, 09:57 AM

Hi Paul,

Pretty sure mine are based on the 3.0 :( . . . one thing I need to check out is what year cats are required from for MOT purposes and whether my car fits into the category that doesn't need them. My car is a 'K' plate so might just be OK. If so, good by cats :)

Minch

08-04-2009, 10:02 AM

. . . . bummer :(

"If your car was fitted after 1st August 1992 with a catalytic converter from new, you need to have one for the MoT. It needs to be in good working order to comply with the Government's emissions legislation. The engine has been designed to work with a Cat and besides giving out toxic emissions, the performance will be reduced if your Cat is not working properly. You will fail the annual MoT if you either it is not present or it is not in good working order. "

Hi Paul, I guess that's Simon's set, I'll take them if P27 sells.

Simon, if you want to take delivery and give them a try I'll take them off your hands further down the line. Unless you see sense and decide to keep P27 :)

Can't let S2 get even further ahead in the power stakes ;)

Hi Guys,

So I recieved the following info from Brian today so we are on the way. I dont know which sets are in the first shipment so it will like Xmas for two of us.

Here is the tracking # for the first 2 sets. The other 2 will be coming shortly. It's crazy how much they are charging for shipping these days! http://www.nsxprime.com/forums/images/smilies/eek.gif
USPS #CP074896165US

It will arrive 6 to 10 days. It is also insured as well and was sent to Paul's address. So look out for it. Thanks again Paul. Please let them know everyone will be getting theirs shortly. You guys have been patient and handling everything with class. Thanks again for helping the UK guys and me out.

Brian

However, it is good news for all of us anyway. Why is this you ask? Due to the delays we have experienced and the way positive way all has been handled, we will not be charged for the shipping of these to the UK. I had agreed this a while back but didn't mention in case the poition changed. IMO this is a very professional response from Brian in acknowledgement of our patience.

So happy Easter everyone, and maybe, just maybe, Paul may add a little extra good news once these babaies have arrived ;)

Just put in the tracking no to USPS and got this reply

Label/Receipt Number: CP07 4896 165U S
Status: Into Foreign Customs

Your item is being processed by customs in GREAT BRITAIN. Information, if available, is updated every evening. Please check again later.

So they are in the country, just need them to clear customs.

The last item I tracked from the US, I received the same message. 2 days later I was a bit concerned when the tracker sad " attemped to deliver on xx date" and they never, I was a little worried. The followong day I received a letter from Parcel Force saying they had the item and as soon as I paid the customs fee to them they would deliver.
.......... so expect a letter!!

regards, Paul

Import Duty £9.67
Excise Duty N/A
VAT £55.20
Other N/A
Parcelforce Handling fee £8.00

Total £72.87

The above is the cost so far but I need to see what I can claim back.

As I see it then

1. Senninha (Paul) .... OBDII NA2 .... ordered 2" fitment
2. Nuno (NSXPrime) .... OBDI NA1 .... ordered
3. Noel Watson .... OBDII NA2 .... ordered
4. simonprelude .... OBDII NA2 (1997) .... ordered 2" fitment
5. NSX 2000 (Paul) .... OBDII NA2 .... ordered
6. DaveMat.....OBDII.... ordered

we are due 1 91-94, 3 95-00 and 2 01-05

So reckon it's the the 2 01-05 cats in the box.

I'm almost certain that the OBDII cats are different between a 97-00/01 car and an 02+ car. This is why the 3.2 version headers are different over the years also...

I think Paul may have mentioned this on Prime to Brian....

Yep I know.....it's just that Paul (NSX2000) has an 05 car and I think the later ones haven't been made yet so although Paul took delivery his won't be in the box!! :angry::angry: Paul (Finch) should be able to confirm or correct my comments...

The two sets received today are for 95-01 cars.

The remaining 3 sets are 1 x 95-01 and 2 x 02+ sets, all of which should be shipping after the bank holiday

Not long now. Noel, I know how keen you were to get these on for the top end runs! At least you can compare b4 after top speed runs and impact of the cats on the rest of your mods

Paul,

Thankyou for being so persistent with the chasing. I've been reading the Prime thread

http://www.nsxprime.com/forums/showthread.php?t=106549&page=5&highlight=flow+cats

and can't believe it was almost a year ago we started talking about this. I'm hoping we can overcome the small problem of

"The single 02+ order will be last. "

and then we can arrange another TDI morning to see what the numbers are.

I have 3 really good friends with parts out-standing. I have my set in the shop but I wont fit them as its not fair to the other guys.

PLEASE ... make these your priority. It really doesn't help seeing you working on other projects when these are still outstanding.

I really have been so tollerant to all the next week / 2 weeks / moving shop / suppliers delays and simply want the items we've paid you for.

So please, close off these orders and get the guys their parts shipped before they miss another summers driving.

Cats are done and ready to be shipped. I will have time to ship it out tomorrow. Thanks again Paul for your patience. I will PM you with the tracking #. The same address I shipped the other cats should be good?

I've asked for shipping to Paul as before, with the same package labelling.

I hope they do as I'll then fit mine ... didn;t feel right knowing you guys were still waiting.

Just a thought but should we consider a group install by either Plans or TDI? Might be beneficial to the wallet if we line up all 4 cars. If we used TDI for example they have said they would do b4 and after runs.

We all have before dyno's from TDI though. Sure an on the same day, before and after dyno would be best (to judge the gains) but a fit new cats then dyno would probably suffice?

Maybe we just chose one car to do the full before and after dynos on?

I spoke to them last week and they asked me to take the NSX in for them to have a look at and work out time/costs.

Also, when I spoke to Kaz about it he suggested it would be benficial to have a spare sensor as it quite possible for at least one not to work or get damaged in transfer.

If you guys are in agreement I'll ask TDI if we could do a group booking and maybe have a couple of cars done simaltaneously (I'm sure thats spelt wrong!! :no:)

Hey guys glad to hear these things are going to turn up soon.....What was it, June 08 you ordered them? Problems or not at their end it does take the piss.

Anyway the reason I chimed in is to concur with Kaz's comment on the Lambda sensors....When I put the 02+ system on my car sure enough the sensors failed and on popped the warning lights!! Just make sure no oil, penetrating fluid or such like gets on the sensors, that's if you get them out ok. They can be stubborn buggers....

I'm keen to here how good they are in both power and sound enhancement. I considered ordering a set a few months ago with the theory of picking them up when in the US last month but the eternal wait you guys have enduring made me decide against it...If they are any good I may reconsider a purchase in the future, I was thinking of delivery just in time for the Olympics:rolleyes:

Hope it all works out good in the end....

Good luck getting hot cats off a car.:)
If it's the first time the cats have been removed off a car, be prepared for a long time doing it. The nuts will be rusted to the studs, and in the cases I have done, need cutting off.

My car would of been perfect, as when I removed the cats, I also removed the studs from them. I used stainless bolts through the exhaust flanges to the cats so I could switch from cats to test pipes in minutes.

Getting the studs from the cats involves a lot of heat from a torch to expand out the cat so the stud can be removed without bashing the crap out of the cat itself.

markc

01-10-2009, 10:58 AM

Sounds good, assuming we can all make the selected date.

In case it doesn't work out, I have an O2 sensor socket if anyone wants to borrow it. I will probably get under an "crack" the seal on my sensors prior to our fitting day.

Gents,

Popped in to see the TDI team today. I will be getting details from them early next week.

On inspection there a few parts that would smooth things along and I will pm details.

We will need to decide if we want before and after runs on the day. If you do (I'm not too concerned with a before) then remember this will extend the time you need to be at TDI to allow for cooling.

I'd suggest we aim to meet on the agreed day for a brekkie early to allow the crs to start cooling b4 TDI opens around 9ish.

Paul's on the money at around 2 hours per car plus the run for the good, or not so good news!

Catch up soon .. anyone tracked the parcel?

One at base of header wont need to be touched (as I understand it), but there is one after the cat but part of the cat itself that will need to be swapped over. This is the potential risk area in that they can fail even if treated with care. I've also been told not to use releasing agent to help removal, instead should use heat to release them. When I spoke to Kaz about these he suggested that he wouldn't undertake this exercise without having a spare to hand 'just in case'. OEM is costly but can be obtained from US at good price. With 4 cars to do maybe worth investing in a couple??

You can get them for about $60 in the USA.

But they all have differant length leads so you'd have a 1 in 4 chance of buying the correct one.

Shouldn't be a problem as you can buy the one/s with the longest leads and lose the extra wiring or just cut off the connectors from both old and new and solder on the old one to the correct length.

markc

14-10-2009, 05:46 PM

If you increment up throught the years from 1997 to 2005 (and stick with the same manufacturer, such as Bosch), the part numbers change at least twice.

Are the LEV cars fitted with wideband O2 sensors?

The O2 sensors fitted to the earlier cars are fairly dumb devices. I would hazard a guess that the part number changes are for length of cable or position of strain relief clips etc, the actual sensor will probably be identical.

I fitted a generic Denso to mine and it cleared the problem and has been fine since.

Paul, Noel and myself had our shiney new cats fitted at Plans Motorsport today :)

No problems with O2 sensor damage/failure, at least after a short test drive and when we left.

The cars sounded a little bit fruitier on idle and when you blip the throttle. I can't say I noticed any differance in the sound level or performance on the shortish drive home but it was in slow rush hour traffic. Time, and the TDI dyno, will tell.

Paul (F) my fit wasn't as straightforward as Paul and Noels due to the new cats having a different (wrong?) size thread. In fairness it may be that my car is "odd" or that it's a JDM thing but your car may be similar.

Unlike Paul and Noel's later cars, my car has different style/size O2 sensors on the pre and post sides of each cat. The post cat sensors are a smaller size so they just fell into the fitting holes in the new cats.

The chaps at Plans didn't bat an eyelid though and after quick rummage found some nuts of the correct thread size and preceded to weld them onto the new cats. Hey presto my O2 sensors now fit the cats :)

They charged me a very reasonable extra 30mins labour for the fabrication so I'm a happy bunny. If I get some horsepowers (sic) as well even better.

Thanks to Paul (F) for arranging and persisting with the group buy and Paul (S) for handling the shipping and organising todays fitting session.

To add to the above, it took the plans mechanic and I an extra 10 or so minutes to figure out which hi flow cat replaced which standard cat. The reason for the confusion was caused by the location of the O2 sensor hole, on one of the cats it is located on the left and on the new hi flow cats it is on the right:doh:

So am I happy with the hi flow cat? Not sure yet will have to wait and see what the dyno read out is like.

I needed a pair of oxygen sensors 2 years ago and bought universal 4 wire versions at about 7 pounds each off eBay. The sensor itself is (as they say) universal, only the manufacurers plug changes. You need to attach your existing plug to the wires using the fixings that came with the sensors but it wasnt difficult. 5 mins with a soldering iron and some shrinkwrap did the job without even using the fixings. So far no problems and at that price relative to OEM who cares if it has a slightly shorter life.

All true but in my case I have 2 different physical type/sizes s of O2 sensor. The pre cat ones are larger, the 18mm thread variety, while the post cat ones are smaller 12mm thread, variety.

I had to change a pre cat o2 sensor last year and ordered what turned out to be the correct one via www.oxygensensors.com but had I needed a post cat one I'm not sure I'd have received one that fitted?

Had an eventful day outside of a very quick install by Plans for my Prospeed CAT's.

On the CAT's, initial impressions are all positive. Tickover remained smooth, low revs showed little change but car quieter on cruise. Real difference felt from 5k upwards with snappier throttle response and improved sounds in and out of car.

I even had a rather nice compliment about the sound from a very helpful traffic cop on the way home :rolleyes: ..... so maybe I did get a little carried away with the new sounds

Hopefully we'll get these tested soon at TDI, and invite a few other owners. If there are gains it would be a nice upside. But based on todays drive home, it certainly feels and was recorded as quicker!

Everything was a straight swap with no mods needed. The only tweak was to run a bead of sealant around the new gaskets to ensure no leaks and is fine.

I'm guessing yours may have been a JDM issue?

Hi, Mark.

I believe your NSX is JDM 97 Type-S. If this is the case, then your model type is E-NA2 and not GH-NA2. Therefore, the smaller diameter sensors on your CATS are the exhaust temperature sensors only on JDM. They are not the O2 sensor.

For JDM NSX, the secondary (post CAT) O2 sensors were only introduced from Sep/99 GH-NA1 and GH-NA2 models. From that point, these exhaust temperature sensors were removed from JDM NSX.

In fact, these temperature sensors were not used for EFI calculation but purely for monitoring and warning purpose. You can remove them and put blanking plugs on the CATS and cover up the holes at the right side of the boot.

The sensor that Ary was talking about is the same temperature sensor as it was E-NA1 Type-R.

Hope this will help.

Kaz.

I'm popping across to see Ewan tomorrow morning. When his went he had slightly different symptoms. Mine only seems to trigger when I am using the engine properly - pottering around town or to the gym it is fine.

You could try the spark plug anti fouler in the CAT sensor hole as per the S2000 guys.

The sensor could be saying the CAT isn't working correctly therefore triggering the CEL, an emissions test will show this also and could mean the car will fail emissions so maybe pointless going sportsCAT versus deCAT.

We specifically went for sports cats over decat in order that we can pass emissions, so it will be mildly unamusing if this proves not to be the case!

Noel,

Sorry to hear you have some issues ... arer you comfortable nothing was damaged on install? It seems strange that only one of the 4 sets recently installed is causing an issue, and none of the earlier sets caused problems either? I'm told the sensors 'can' be very sensitive to being touched once installed? Is it worth a swap out or is the rerreeader frorrom Ewan confirming they are working OK?

Hope you can resolve soon

It is a shame as we all waited so long and you put so much effort into chasing.

The fact that both sets of cats are triggering indicates to me that it is unlikely that it is an O2 sensor problem. Furthermore, driving normally does not flag a problem, it is only when using the car as intended that it flags (when Ewan had an O2 sensor fail the light flagged during normal driving).

As to why mine is the only one flagging, I will check with other Paul (could be an LEV issue where the ECU is more stringent of emissions) to see if he has been redling his car with WOT multiple times in quick succession recently - if his doesn't flag then it may be my bad luck.

Still up for a TDI day - I don't think my car is going in limp home mode - VTEC is certainly engaging.

Hi Noel

Went out in mine on Friday night, only up the road mind, and have not had a problem, touch wood. On my way home after having them fitted I hit Vtec more than 10 times and no problems.

I would agree with Paul, these are very sensitive bits of equipment and plans had to do a bit of extra "bangging" to stop yours from blowing, it could be worth me picking up a pair from the US for you or ask Kas to have a look?

Paul.

Hi Ary, excuse my ignorance but what these and how do / would they help?

As I understand it they move the O2 sensor out of the exhaust gas flow where it (the O2 sensor) reads lower CO and HC (Hydrocarbon) emissions. This usually stops the car sensing a problem and triggering the Check Engine Light (CEL) but of course it doesn't change the fact that the CAT isn't doing it's job properly. Of course it may doing enough of a job to pass MOT emissions but only a emissions check will tell.

The fact that both sets of cats are triggering indicates to me that it is unlikely that it is an O2 sensor problem. Furthermore, driving normally does not flag a problem, it is only when using the car as intended that it flags (when Ewan had an O2 sensor fail the light flagged during normal driving).

I agree sounds like the CATs aren't doing enough rather than the sensors being at fault.

As to why mine is the only one flagging, I will check with other Paul (could be an LEV issue where the ECU is more stringent of emissions) to see if he has been redling his car with WOT multiple times in quick succession recently - if his doesn't flag then it may be my bad luck.

Still up for a TDI day - I don't think my car is going in limp home mode - VTEC is certainly engaging.

Perhaps Kaz, could comment on what the LEV ECU, and indeed the pre LEV ECU, does when the Post CAT O2 sensor/s detect a problem like this?

Cheers

Paul,

They are spark plug antifoulers, they are used to move the lambda sensor away from the path of the gases enough, not to get a CEL.

Good post here:

Good link, these are exactly what I have in my toolbox, I bought a few sets when I ordered my CATS as I had a feeling at least one person would have this problem.

I seem to remember somewhere that the secondary O2 sensor on the LEV ECU does affect fuelling etc but will wait for Kaz to confirm.

If the emissions are ok for MOT time and there is sufficient room for the anti foulers then that would be my way forward. Well unless you can either live with the CEL coming on at WOT (dangerous in my experience) or you're going to revert to OEM CAT's or install an aftermarket ECU.

23-11-2009, 02:11 PM

Would have been interesting to see an AFR plot on the cars before hi flow cats, after and after antifoulers.

Judging by NSX Prime posts it sounds as if the proospeed stuff and company leave a lot to be desired off.

AFAIK Hi Flow cats degrade quicker than OEM.

Any reason why not get a set of Random technology modified for NA2?

I'd would have gone this route from the beginning. They're more reputable. But cats won't bring much anyway.

Some similar problems (P0420/0430) with the Random Technology ones so not sure you'd be any better off with them.

Anyway don't rain on our parade just yet you miserable buggers :)

Nice to see the product experts have joined the fray ....

Some positive comments to assist Neol with this issue are obviously welcomed, but if you have hearsay opinions then keep them to yourself please as they offer no help.

Noel,

any chance you can swap out to test if it is a damaged sensor?

Well, as Noel says, it appears that his O2 sensors are working "correctly"; mine had a heater circuit malfunction, which was causing the CEL pretty much as soon as the engine was turned.

Looking at the pic I took at the time
http://www.nsxcb.co.uk/testvb/attachment.php?attachmentid=4545&d=1222537533

It seems likely that both post-cat sensors could accomodate the anti-fouling plug Simon's suggesting - there's a reasonable amount of room there...

Noel: if I were you, I'd have the car back to Plans to see if they can check the installation is OK, maybe get them to do an emissions test too?

cheers
Ewan

Paul/Ewan,

Will give Plans a call. The weather map tomorrow has a round yellow symbol on it. I recall this is named sunshine, and as I haven't seen any for months, may take day off to enjoy it. Not sure if Plans do emissions tests, but if they do, I will see if they can squeeze me in.

Emissions were fine, not much different from last MOT, so maybe it is only higher revs that causes the issue. The chap that did the check

used to MOT McLaren F1s, so I explained the link between ours and the F1. He took a photo for the website.

Hi, Noel.

As other owners using the same high flow CATS didn’t experience the same issue as yours, it is very unlikely to be the CATS failure but more of sensor or installation issues unless you had the unlucky one. Emission test won't highlight much because the EFI closed loop is based on the Primary O2 sensor and not with the Secondary ones. Also, your CATS are new and if it is performing as it should be, you won't see any spike.

The secondary O2 sensors are not used for the closed loop EFI calculation. They are used for monitoring the performance of each CATS. There could be a protection algorithm for the CATS within the software but only under the fail safe condition and not for the normal EFI calculation.

You may want to put back one of your original CAT or replace one of the secondary O2 sensor for testing purpose. Also, if you have any leakage around the CATS gasket, you will trigger the ECL. I hope you replaced the gasket and using the round edge type and not the flat ones.

If your DTC reader has monitoring/plot feature, you may be able to watch the output data from the secondary O2 sensors. Alternatively, any high performance tuning shop should have CAN interface with PC software for monitoring different parameters in realtime so you should be able to monitor what is happening at WOT (Wide Open Throttle). This will tell quite a lot of things and since you have other owners with OBD-2 NSX, you can compare the data.

The sensor itself is narrow band so it can be tested in several ways quite easily by applying voltage at the heater circuit and monitoring the output voltage at certain rpm.

Regards,
Kaz

Any chance they use penetrating oil during the install and contaminated the sensor somehow? Perhaps some cutting fluid from the threads in the bungs?

Just a couple of ideas that might have nothing to do with it at all.

Cheers,

AR

Thanks for the reply. The above rings alarm bells. We had problem getting a seal when fitted so it wouldn't surprise me if this were the problem.

I downloaded the commercial version of EasyOBD11 (free version may be adequate but I felt that it was worth a contribution as it is a decent product) and went for a spin.

Got the following:

Av Bank 1 Sensor 1: 0.46v
Av Bank 1 Sensor 2: 0.58v
Av Bank 2 Sensor 1: 0.49v
Av Bank 2 Sensor 2: 0.58v

From

http://en.wikipedia.org/wiki/Oxygen_sensor

"The ideal setpoint (http://www.nsxcb.co.uk/wiki/Setpoint) is approximately 0.45 V (450 mV) DC"

So it appears that all four sensors are working OK.

The light didn't trigger today - maybe wasn't pushing hard enough as motorway was busy and roads are cold. Will give Plans a ring in the week and get it booked in.

So, popped down to Plans and we are pretty convinced that the exhaust isn't blowing. We tried stopping the exhaust flow and it was impossible, so there is a good seal. Next steps

1. Need to plug diagnostic gear into Paul (NSX2000s) car to see what his sensors show
2. Get the cars on the dyno at TDI
3. Decide whether to keep them fitted.l

Blast from the past - put the OE cats back on - just back from SRR - car is 20bhp stronger at top end - back to where it was before. Also had tracking done. Car feels so much better.

markc

Car feels so much better.

Power wise, handling wise or both?

Assuming the former, were the Cats causing a physical flow problem or was it the O2 readings causing the ECU to hold the power back?

Both!

As for power with sports cats - I think it was ECU rather than flow, as the power curve was doing some strange things at the top end - dipping down after 6000 and rising slightly at the end. I'm just chuffed I don't appear to have done permanent damage.
