nsx engine?

I almost did a k20 swap into my 7th gen civic , lots of money but I was going to go through with it, but it was a LOT cheaper just to get the wrx and run better times with that.

Bryce, that kind of compression would require low boost (which is the likely route) or a ridiculously high octane fuel. Although you'd probably see a rod punch a hole through the block before you'd experience detonation. The K24 would be better for a turbo, although I'm fairly certain that AFR is around the 10.0:1 mark as well.

boost magazine (from car & driver i think...) put a supercharger on the k20 and ran like 4.7 psi. actually, there have a been some arguments on honda-tech about which is better for a turbo: high or low compression. low compression means more boost for xxxhp with significant lag, whereas higher compression means less boost for xxxhp with a little less lag. i think the #'s were 9:1 vs 10:1
granted, many other factors come into play (fuel mainly), but that was the basis for the argument -
Here is where I got my infromation.

My original impression was that the K24A was in base, and the high revving VTEC K20 was in type S. Like in Preludes. But I guess both base and type S have a different version of the same engine, K20x.

the k20 is in the regular RSX and has 160 hp
and the k24 is in the Type S and has 200 hp
from what i have heard and seen i must be wrong. -

nvsgsx...nope the type s is still a 2liter
why would he swap from a 200hp k20 to an H22?
doesnt the k20 have something different like i-VTEC...im not sure what exactly has changed but id like to see someone mess around with that motor a little bit and i bet youd get some good results...

well if u like k20 200hp over the h22 220hp. i guess i would take the h22 but thats a prelude motor who puts a h22 in a rsx i dont no there both great motors

I-VTEC>VTEC
I-VTEC is very new, as in 2002 it was released when the 2002 HB Si came out. The k20 and the k24 are awsome engines and have tons of potential. ( Correct me if I'm wrong )
VTEC has been around since 88 in japan. H22 is a great engine but I'm pretty sure that no one makes mounts for a RSX H22 swap. And WHY WOULD THEY?
