hey guys, i was wondering what the potential is of an NSX going N/A? anyone have ITB's on an NSX or know how much whp it puts out wiht the ITB's? any hytech kits on this car? thanks guys.

 

That's a short question with many long answers. Do some research on NSXprime, where you can find a lot of information about the NSX, and results of various mods. Click here for the NSX FAQ (answers to Frequently Asked Questions), and click here for the NSXprime forums, which have a good search function available on them.

 

I think the most extreme examples of max NA power is with the JGTC NSXs which make a regulated 500hp. I've heard street versions with ITBs make anywhere from 350rwhp to 380rwhp.

 

get ready to spend tons of cash on n/a setups. and the potential for "any" car going n/a is only limited to the money one wants to spend.

ITB's/cr/stroker/ etc etc are very pricey, especially on a nsx.

i've seen stroker kit for like 15g's.

I think that's a little optimistic. Japanese tuners claim those values but I think those are crank values so maybe 310-320whp at best.

310 whp at best??? the 3.2L dyno at 260+hp.. and ur saying a FULL n/a setup will only gain 50-60whp? i/e/h/cams/cr/itbs/etc etc that's well over 50hp.

remember.. japanese turners are TOTALLY different then americans. these guys are hardcore when they come to getting hp.

 

If your real serious this turbo kit will get you quite a bit, http://www.turbo-kits.com/nsx_turbo_kits.html , but its expensive.

Interesting, I did not know that cartech finished their kit. Interesting to see that they chose AEM for fuel management. Not a bad combo for 8000...

As for NA tuning, I'm sure you can get higher in HP but for anything remotely streetable, I wouldn't expect more than around 320whp. I have yet to see NSX NA dyno that shows 320whp. I'm sure someone has done it, but haven't seen it.

 

FWIW, there's a Dr. around here that did the whole Comptech I/H/Cams, etc. and got right at 320rwhp - or so it's been said. I've only met him once and he rarely brings it out. He's got the Comptech supercharger now.
