Noise levels

[marknsx]

Has anyone removed the sound isolation behind the seats of an NA1? If so is it bearable over long journeys?
Thanks

[britlude]

is this to lighten the car, or something else?? the sound insulation is combined with a rubber sheet and goes over and behind a lot of stuff! you'll have to REALLY want to remove it as it's not a quick job!!!

it's noisier just removing the top trim panel ..... that'll reveal the relays, control boxes and computers that are in front of the insulation....

Just an idea to reduce weight. Honda dealer is preparing it for me. Seemed like a good time to ask for any mods. I think then just some Bride bucket seats.
Many thanks

Hi Mark, IMO why waste money on gaining mechanical noises (not exhaust notes) into the cabin while not saving any real weight that you'd notice.

[britlude]

might be worth a look here.....

You'll also remove the heat barrier.

Interesting list and information there compiled over the last ten years and no where did I see listed or mentioned ever removing the engine bulk head sound proofing, I suppose if it had been suggested that the same person would have probably suggested removing all the carpets, door trims, roof lining and body paint.

Now that would be radical:)

Creature comforts rule!!!:rolleyes:

[marknsx]

Thanks to you all for your input. lots to think about.
I wanted an original car which I now have. So why do I want to modify it? mad!! Originally I wanted to match the weight of the Type R. I read that to achieve this weight loss one of the items to remove is the insulation. A nice bit of kevlar or even asbestos would make a great replacement soundproofing.
I still like the idea of adjustable Bride seats!

Hi,

Do you have a coupe or T-Top? What are your objectives for reducing weight? And what have you removed so far?

There are far simpler ways of reducing weight such as spare wheel, engine cover (particularly for the T), Seat swaps, side scoops (NSXGB has a carbon set for sale I think) ....

It then gets a bit more challenging but of course, as a rule of them, every 10lb is worth another hp so more 'effective' power with the cost.

Good luck, Paul

[marknsx]

Thanks
All original. No changes yet as I haven't taken possession. Honda are selling to me and we have an agreed schedule of works as a part of the price I'm paying. New windscreen, removal of rocker covers, cam-belt replacement, paint to several areas, refurb of the original alloys, repairs and refresh to drivers seat, service and re-gas of air con.
Whilst they do that Im looking at simple mods such as the seat replacement. I can ask them to remove remove the spare wheel and bracket. Im doing some european driving and wonder if keeping spare and the tools for this. Or do i rely upon the breakdown cover in the case of a puncture?
Tell me about the side scoops. What does it involve?

[marknsx]

Its a coupe

Tyre on spare wheel probably not good enough to use any more. Can remove totally for a good weight saving or search the forum for alternative solution if you feel more comfortable carrying a spare. Otherwise a can of tyre weld and AA membership should suffice...

Side pods and B pillar covers are cast ali and are pretty heavy. There are vendors selling CF replacements to save a lot of weight.
To remove side pods it is necessary to remove rear wheel and half of the wheel liner to gain access to the 2 x special nuts which hold them on. Can be very easy if you have small hands or you may need to loosen the nut with a short 22mm spanner. If the bottom nut is a PITA you can remove the side skirts very easily to gain access.
B pillars you will have to remove the main 5 rear bulkhead panels behind the seats, inner B pillar covers and drop the headlining down carefully to get at the two 8mm nuts which hold each of them on. Very straight forward.

with the removal of the spare wheel and bracket I'm thinking it would make an ideal space for more luggage.

This was done a few years ago but the bracket was retained for support see post 29

Thanks Rich. Should be able utilise that space

[havoc]

I'm not certain that squashy bag would be OK on a road-trip.

I started that thread and ended up fabricating a small stowage compartment using a slimline kitchen storage tub (~15" square by 4" front-to-back), bolted to the bracket.
It stayed in place fine...but the plastic itself got a little too warm on the journey at some point (as did the contents), so I suspect the heat kicked-out by the rad/fan is quite a lot.

If I was doing it again I'd put some foil on the front of whatever I stowed and probably angle it so the air is deflected downwards. But I discovered the better bet is to marry someone short and push the passenger seat forwards! ;)

[marknsx]

my Honda people reckon that taking out the spare wheel will alter the fine balance that Honda spent so much time engineering! So I need a suitcase or picnic hamper of the same weight

[duncan]

What is the optimum petrol your "Honda people" advise to have in the tank? Likewise the balance of the drivers weight to that of the passenger and of the density of the items in the boot?

[marknsx]

I have asked the question. The cars optimum is a half tank of petrol and a total weight diver passenger equiv to 23 stone and a bag of cement in the boot

[duncan]

Who are your Honda people?
To remove 30lbs (spare wheel and bracket) from the front axle = bad,
to add 112lbs (bag of cement) 18" beyond the rear axle = good.
If you really want an over weight, rear heavy car, it might be easier to start with a Porsche.

[marknsx]

aaaaaagh a porsche!! my wife's choice not mine! Never!!!
Truthfully the bracket and spare wheel were a weight saving idea. But only that. I will be trying to keep to the original car spec as poss as that is the way it was built.
I want to tinker but musnt. Having said that I wnaat to drive it. I love my road trips and want to do some. Any thoughts on replacing the seats, which need restoration. Any idea of which aret the best sports seats for comfort and safety and fast long distance driving? Also where to get them? (I have very intention of putting the original seats back when i sell).

[Silver Surfer]

The original seats are the best for comfort and support.. The recaros are really no better and the weight saved is not worth it.
You are better of re-upholstering it with newer leather which can be done for £800-900 both seats. (See 'New interior' thread)

Great. How do I find your thread

[britlude]

i've retrimmed too, using leatherseats.com replacement seat covers....

Mark,

What Ive not seen offered yet is the following ... leave it alone.

Drive it as it leaves the dealership for at least the summer. Drive it in town, cross country and on one of your roadtrips, and whilst doing this build yourself a 'wishlist' of how to make it yours.

With weight saving you need to keep the balance so what comes of the front needs to come of the rear and vice versa. Check out threads on here and on NSXPrime for ideas good and bad.

Seats, the Honda Recaros are as comfortable as the OEM but nigh on impossible to find. The often used Pole Position are not as comfortable. The OEM seats are heavy but are very comfortable and supportive and as Silver Surfer suggests, a good quality retrim works wonders. Depending on your NSX colour maybe bespoke the colour to have something unique?

What ever you decide, enjoy your NSX.

regards, Paul

Common sense. I am instructing the boys to have the seats refurbed and leave the car as built. Excellent advice from all. Many thanks

Having owned and been in love with car audio systems for 30 years I would strongly recommend the Alpine eX10 interface.

I've used one in my car for the last 10 years and it's pure quality. You can install the bright colourful display perfectly in the glovebox on your early NA1 as you operate it with ease via an easy to use remote control when you open the glovebox.

If you find negative feed back from comments or reviews it's because those people never hard wired it with the optional hard wire interface.

If interested Mark I've got a brand new boxed unit and optional interface from my old stock I have left over.

[marknsx]

How much is the unit selling for

How much is the unit selling for

£100 +15 for optional interface +£10p&p

is this the current unit from Alpine? Or have they upgraded?

Discontinued now and they never replaced it with anything that operates or sounds better.

Now the Alpine head units come ready with Bluetooth connection but that means changing the great OEM unit.
