what really adds hp? what really adds speed? f22a1 engine stuff? has to be naturally aspirated need help. has factory header on it now, 91 accord ex.. what really makes a difference?

NerfGunner420

intake manifold, cam, exhaust system, high compression pistons with boring and head porting as well. and last a tune

MAD_MIKE

A6 is mostly the same engine, larger cam, windage tray, different intake manifold and of course the ECU. That makes 15HP more than your engine.

Slap on a turbo and you should be able to gain 40-50HP with mild boost and good tuning.

With regards to speed aspect your wheels you run make a huge difference. Lighter skinnier wheels mean faster road speed. Then on that subject bulk weight in the car can be a difference. Replacing parts for lightweight and removing unwanted accessories like a/c, rear seats, spare wheel etc

What's your goal?

TheRookie74

We race on a dirt oval against the mustang 2.3s with the solid lift heads-long rod bottom ends I wanna outrun them, every week we get our a"" handed to us weekly due to them murdering us, we have even went from a 15 inch tire and wheel down to 13s and still getting murdered

KcAccord

p12 ecu from a prelude adds 5+ hp, you can try that.

chrisnick

What do the rules allow?

NerfGunner420

for real where in the heck was all this information at? did i miss it in the op's post? did he post it in another thread or something??????

NerfGunner420

i know there has been two threads on this already...... um couldn't find them but they are floating around here

Uh what? I really doubt this claim.

KcAccord

the 4th gen prelude S came with a f22a1 rated at 135hp, the IM and exhaust are the same so the only difference i heard is the ECU heard this claim on cb7 forum and the benefit is small but with some a6 upgrades you get more out of it. (correction 10+ forgot the f22a1 accord is rated at 125hp sorry)

chrisnick

"Rated" vs "Puts down" are different things. It could very well have a more aggressive tune on it, but from this standpoint, it's moot.

Sure enough, looks like guys are doing it. I doubt the difference is noticeable though. Rated 10hp higher isn't going to really feel like much of a boost when it gets to the wheels.

TheRookie74

we have open rules other than no nitrous-turbo-supercharger, limted to a sohc only we aren't aloud the dohc engines

h22a intake will fit a f22a1 head?????

chrisnick

No. But it will with one of these:
Evolution F2H Intake Manifold Adaptor | 29611

Also, a K-series intake can be made to fit with relative ease, too. Takes a bit more fab, but it can be done and K20A2 intake manifolds are cheap and pretty efficient to 7500ish RPM.

TheRookie74

Sweet thanks Just spent $600 between my new Skunk2 pro series h22 intake and that adapter

chrisnick

Cool. Interested to see what kind of results you get out of it.

TheRookie74

Im curious as to what size throttle body& what size injectors to run. Considering engine is stock other than the fact im changing intakes-ect May also consider changing the Cam over to a A6 and that ecu..

chrisnick

If you're going to change the camshaft, might as well get it reground to something more aggressive.

TheRookie74

what would you suggest?

NerfGunner420

H22 SKUNK2 MANIFOLD GO WITH 70MM and bore out the intake to the same. the cam, look into webcams which is the manufacture that use to make regrinds for bisimoto.
