what about with 11.5 on a 3.0?
i was thinking about going the NA route, but it doesn't seem like many go that direction without boring/stroking the engine.
i'd be interested in keeping the same displacement, upping the compression, and doing all the other NA mods. what kind of HP could be attained in a setup like that?
Thanks for the link mate. So they are claiming 358 BHP. That sounds like a good number for an NA car.
Cheers,
AR
that's it? nobody else has done the NA mods, while staying true to the 3.0???![]()

I did...
The only 3.0 engines with increased compression ratios, cams, etc. that I've seen data for are Comptech's. Attached is an article from the May 1994 Car & Driver that I've just dug out of my basement.
Some more data about these engines is in the NSXPrime FAQ section here.
Have you increased the compression ratio? Can you get Cometic head gaskets for an NSX that are thinner than stock and thereby increase the compression ratio? If so, by how much?
When you had your cylinder heads off to install the head gaskets, did you have the heads ported and polished?
My only regret was I didn't have the Comptech adjustabe cam gears installed since they were out of business at the time of the build.
