Performance Upgrades

BlueNSX has me in his avatar!!! How cool is that, finally recognition.

Anyhoo back on topic ref. air filters/induction. From my point of view, a decent filter on it's own will do very little if anything at all to performance, but when added in addition to a better exhaust, then there will be a little gain, if you make the car breath in easier, it has to be able to breath out easier. Hopefully when I finally decide what exhaust I want, I'll get a decent air filter too.

I was considering the
Dali - C/F intake scoop with the Apexi Filter and the conector to help the car breath does anyone on the forum have this ?

Exhaust-now thats a bit tricker, what are the best headers ? AR suggested EQUAL LENGTH HEADERS (Taitec) who make/sell the best bang for your buck as far as headers? Also do you keep the standard Cats (sorry to repeat a question asked in another thread)? Or Replace with higher flow units?

Senninha, thanks for the advice on steering wheels.

Barry from V-Tec direct ( on this board ) can get you a good deal on Taitec Headers.

As far as cats, it all depends on what you are after, hi flows are expensive, might as well get test pipes, and swap back as needed for test etc. You wont get much BHP on an otherwise stock NSX, but IMHO it sounds better, and revs better too.

How much difference does I/H/E/cats make in the real world? You could spend 2-3K on these modifications and get what,20-30 BHP if you are lucky? How much difference would those mods make on the road?Obviously everyone who spends that sort of outlay wants to believe that it makes a difference,but does it really?
Just curious.

I feel the difference, the extra horses and weight reduction certainly help the car.

But YMMV.

Weight reduction yes,but i'm talking about just I/H/E.

Is pretty much an aknowledge fact that the 3.0 exhaust manifolds are heavy and restricted. For me 20 BHP feels like a hell of a difference. I will venture out to say that if one was to put 3.0 manifolds on a 3.2 one would loose a lot of power and be on par with a stock 3.0.

In the real world it doesn't bring that much. I certainly feel a difference but it's far from night and day. On a 91-96 they're a MUST as you gain 20 hp for sure with H/E. And if you feel the car you should feed the 20 hp. On a 3.2 these mods are questionable, esp. the header.
One nice mod is the SOS chip if you do H/E, + 10 Nm.
I've once installed a CT exhaust and it felt more breathing than with the Remus. Also saw this on the dyno. But I went back to Remus as the CT was simply too loud and felt it was more restricted but not by much.

What is important is the hp/£ ratio.

Obviously everyone who spends that sort of outlay wants to believe that it makes a difference,but does it really?

Yes, I know these people. The more they 'invested' the better the car runs THEY CLAIM. They even get trapped by the wrong dyno proofs of part x versus stock. The intake is such a part. +4 hp they claim, haha, that's within the variance of the dyno machine.

Don't see the point of the cf intake as it's not seen, Down Force do a FRP one for about £100 delivered to the UK which is a lot more reasonable and has to be just as good.

From what I've read, the OEM filter element has a decent flow to it and isn't worth changing.

I have done most of the mods you are asking about in stages and could not tell you whether the car has much more power (I would obviously hope so), but definitely noticed a more free revving engine along with the more exotic noise.
Definitely a slippery slope when you start...

I'd stay with the OEM air filter too. For the intake, regardless if it's FRP, CF or even plastic, you won't see it installed anyway.

In general: I went through the more hp and the less weight scenario. And from what I've seen is that it's quite difficult to save weight. The header is a good example of giving more power but less weight. If you do the exhaust too you could gain there in both ways too. From that on it'll get hard to save weight unless you don't care about commodities like A/C, stereo or money.
