Ok, my friend is building a motor w/ a pretty large turbo on his h22a motor. He's looking to purchase portflow dual valvesprings retainers, and ferrea standard sized springs. He's going to need all the extra rev's he can get to keep this turbo in the right range so he's looking to rev to 8-9grand. With the right cams, would this setup be okay?? Also what cams do you think he should run?

 

anyone?

The valvetrain set-up looks good.

I have no clue who manufactures cams for the H22a that will STILL produce power up to 9k. You might want to look into webcams and see what kind of customs you can get. I know Papadakis's set-up puts out over 600whp and he stops making power around 8k rpms if I remember correctly. Most H series motors start to peak out around 7800-8000 rpms. Keep in mind the rod/stroke ratio of the H series motors... they do not have to rev up to 9k to produce power.

 

This won't be much help because I don't know what manufacturer this stuff is, but my friend races SCCA with his Lude and it revs to 11K.

 

tell me more.

 

With a properly built head and bottom end an h22 motor is capable of spining up to 9k's and more. I would look into web cams and tell your frend to get a really good intake manifold. The stock h22 manifold just doesn't cut it, it robs it of power and rev capibilites. Wait till the AIR comes out.

We actually have a couple guys here who rev there h22 to 9500rpm.

 

i have toda springs and retainers plus valves
with type -s cams fully built bottom end w/hondata stage 4 with all the options.just got back from the dyno and did 275 hp and 225 tq @ 7 psi.

i built this motor for a customer and now he cain't pay the bill so,i am going to take the set up out of the 93 prelude and put it in a 93 hatch and turn up the boost.my red line on the dyno being safe 7500.

 

since when did toda make parts for h22 motors???

 

it's really not the head you gotta worry about when reving the **** out of it, with a good set of springs and retainers, your set. It's the block. Personally on a stock block, I wouldn't push past 8500.

 

harv st. mary got them for me.in case you don't know who that is.thats the guy who tunes the venom cars and a lot of other pro class cars.plus they came in a toda box,that makes it good enought for me.
