NSX technical questions?

[autotecart]

Hello everyone

I was wondering if there were some technical gurus who could shine some light on some specifications for the 04 UK spec NSX that I am struggling on at present for the limited edition poster I am creating? Below are some questions that if anyone can assist with answering them, I would be very greatful indeed.

Can anyone confirm which engine code the 04 UK spec car had?
C32A or C32B

Was the 3.2L engine using a single or dual disk configuration and does anyone know of any info on this on the net?

Did honda test the NSX at Tachigi, Susuka and the nurburgring or was it just one specific location?

What is the diameter of the front and rear anti roll bars on a 04 UK spec nsx?

What are the size of the front and rear shock absorbers and springs compared to the anti roll bar as used on the 04 UK spec nsx?

Are there any UK sites that offer UK specifications on a 04 NSX?

What is the maximum range in mileage you can get out of a full tank on a 04 nsx? roughly???

Does anyone know the weight distribution during braking on the 04 nsx?

What is the kerb weight of a 04 uk spec nsx?

What is the vertical headroom for the driver and passenger from the base of the seat to the roof in inches?

what is the diameter of the uk steering wheel on a 04 spec nsx?

Did the UK 04 car have cruise control as standard or was it a optional extra?

what year was the facelifted model car offered for uk sale? and when were the pop up headlights banned here in the uk?

what is the time in seconds of acceleration speeds from 30-50 mph and 60-80 mph?

Does anyone know the braking distance form 60 or 100 mph to zero?

I would be extremely greatful if anyone can assist me with these last remaining questions as the above will be the last information to insert into the text before it goes off to Honda UK for approval. After that I will upload a thread showing the poster and purchase information

many thanks

Hi, Tony.
Please refer to the followings. My answer in bold text;

Can anyone confirm which engine code the 04 UK spec car had?
C32A or C32B
C32B. C32A is for another model and not for NSX.


Was the 3.2L engine using a single or dual disk configuration and does anyone know of any info on this on the net?
If you are referring to the clutch, then it's SINGLE disk for UK spec 3.2L. Different story for one of the specific JDM 3.2L model.


Did honda test the NSX at Tachigi, Susuka and the nurburgring or was it just one specific location?
For original model, the answer is Yes. (typo; Tochigi and Suzuka)
For later model, not sure about Suzuka but yes for Tochigi and Nurburgring + Hokkaido in Japan. Honda has its new proving ground (testing course) there.


What is the diameter of the front and rear anti roll bars on a 04 UK spec nsx?
For UK spec,
Front: coupe=18.3mm, targa=17.3mm
Rear: coupe & early targa=17.5mm, later targa including 04 targa=19.1mm
Different story for JDM specific models.


What are the size of the front and rear shock absorbers and springs compared to the anti roll bar as used on the 04 UK spec nsx?
Not sure about the actual question itself but if you are talking about the shock and springs, the combination is different between coupe and targa. Completely different story for some of JDM specific model.


Are there any UK sites that offer UK specifications on a 04 NSX?
Don't know.


What is the maximum range in mileage you can get out of a full tank on a 04 nsx? roughly???
More than 400miles.


Does anyone know the weight distribution during braking on the 04 nsx?
Depends on the condition.
Later model has larger brake disk size as well as the Larger Rear Calliper piston. Addition to these, for the Front calliper, the diameter of smaller piston was reduced on the later model to shift the brake balance rearward. Therefore, not possible to provide you with actual figure on brake weight distribution. Almost impossible without specifying other conditions.


What is the kerb weight of a 04 uk spec nsx?
Depends on the model (coupe, targa, AT, MT). Don't have the data for 04 UK model. May be you can check the UK brochure?


What is the vertical headroom for the driver and passenger from the base of the seat to the roof in inches?
Depends on the measurement spec defined by each country/area?
Or, any international spec?


what is the diameter of the uk steering wheel on a 04 spec nsx?
All of UK models were equipped with SRS but can't confirm the actual diameter.


Did the UK 04 car have cruise control as standard or was it a optional extra?
For UK, it's standard.


what year was the facelifted model car offered for uk sale? and when were the pop up headlights banned here in the uk?
The word 'Year' and 'Year model' needs some consideration as it is different depending on the country/area spec.
For example, facelifeted model was available from DEC/2001 in Japan but treated as 2002 model. From Parts list, facelifted NSX in UK is treated as 2002 model onwards.
Don't know about the pop up regulation in UK. May be on UK Gov website??


what is the time in seconds of acceleration speeds from 30-50 mph and 60-80 mph?
Don't know the actual data as gear ratio is different between the country/area spec and it also depends on the conditions.


Does anyone know the braking distance form 60 or 100 mph to zero?
Again, depends on all sorts of conditions.

Hi, Tony.




What is the diameter of the front and rear anti roll bars on a 04 UK spec nsx?
For UK spec,
Front: coupe=18.3mm, targa=17.3mm
Rear: 17.5mm



I thought the rear was 19.1mm?

"beefed up the rear anti-roll bar (from 17.5mm to 19.1), "

[markc]

[/B] What is the maximum range in mileage you can get out of a full tank on a 04 nsx? roughly???
More than 400miles.

Provided you're prepared to dice with the gauge and fuel light. Does it still comes on well under 300miles?


/B] what is the diameter of the uk steering wheel on a 04 spec nsx?
[B]All of UK models were equipped with SRS but can't confirm the actual diameter.

I believe all NSX airbag wheels are 367mm.

Hi, NoelWatson.
Not sure about Acura but all of the coupe model for UK market is 17.5mm for the rear anti roll bar.

However, your post reminded me one thing and I editted my original post.
For UK market, the coupe and early Targa are equipped with 17.5mm one whereas the later Targa including 04 Targa is equipped with 19.1mm one.

I remember having trouble ordering the rubber bush for 19.1mm one through HUK the other day as they don't list it on their system even they sell the 19.1mm antiroll bar....
At the end, I had to ask extra days to the owner and ordered it through Japan.

That's strange because Chris Harris in Autocar mentions a bigger rear anti roll bar when testing the facelift Coupe in 2002 along with stiffer front springs.
Maybe Honda got their press release confused.

Depends on the model (coupe, targa, AT, MT). Don't have the data for 04 UK model. May be you can check the UK brochure?



UK Brochure states 1445kg for Coupe MT 1500kg for the Targa, 1485/1530 for AT versions (don't ask me why it's +30kg for the Targa but 40kg for the coupe)

[Ferris Bueller]

I got 420 miles in mine (filled it again before the fuel light came on) and it was just under 60 litres to brim it again. That was almost exclusively cruising. Driven as intended then 250 was the norm. On average I used to get about 300 miles.

[Ferris Bueller]

?

What is the vertical headroom for the driver and passenger from the base of the seat to the roof in inches?



930mm (3.0 car tested in Autocar 23.3.94)

Post 2002 cars performance figures aren't easy to come by......

30-50 through the gears is comfortably under 2 seconds.
60-80 just over 3.

60 to 0 2.8 secs (Autocar 2002 Test).

Stupid question........if talking to Honda why don't you get the data from them?

Similar number s to what I achieved cruising across Europe ... but as you say, when 'used' it drops quickly :D

Mine was 1350kg with 3/8 tank of fuel.
Handbook says 1375-1430kg for Coupe.

Is yours 100% stock, as in no weight saving mods?

[NoelWatson]

It was then - this was at the last TDI day on their corner scales. I hadn't removed wheel or toolkit, so reckon with full tank would be around 1390kg.

At present I want to present them with a concept for the poster with the information as accurate as possible and then they can correct the info as they see where it is inaccurate. But having said that I should just pass these questions by them to see where they stand.

It is strange that there is so much conflicting information out there though.

Just measured and it was just under 18mm, so appears that Autocar got it wrong.

Mine is an early 3.0 so not relevant for data.

During my euro road trip we made the mistake of crossing from Germany into France late afternoon on a Sunday - and only once we were commited to epic roads did we realise that the fuel was getting low, and there were no towns, let alone garages that would be open!

With the fuel light on I ghosted the car 35 miles and breathed a sigh of relif when we found a campsite. I have never driven so economically! The following morning I got detailed and specific directions to the nearest garage. Only to find there were still 8 litres in the tank!

When my fuel light comes on I now know that 50 miles is perfectly possible. I tend to refuel shortly after though to minimise the sediment at the bottom of the tank getting swilled around the engine.

Motorway running I would expect the light to come on around 400 miles.

[TheSebringOne]

Most cars in general have about 2 gallons left when the light comes on. Officially the NSX has 2.4 gallons or 11 litres, so with economic driving I assume you could get 25-30 mpg, so may be 60-80 mpg? This is on the 3.2, not sure the same as a 3.0?

[Kaz-kzukNA1]

Hi, all.

All NSX uses float type fuel sensor so each car has some deviation but for most of them, the low fuel warning light will start to blink (on and off) at about 15L left depending on the angulation.
Then, it will starts to stay On at about 11L left.
You can go down to about 3L left in the tank but you will feel sudden loss of power due to low fuel pressure at high G or on the slope. Down slope seems to be the worst case.

Please avoid this situation as no fuel in the injector is not good for the injector needle.

Similar result for both 3.0 and 3.2 engine.
