400 whp with built H22

[kamaccord]

Can anyone tell me the items needed to produce 400 whp with my H22 Accord? The engine was recently rebuilt with 8:1 compression pistons. The turbo I plan to use is the Precision SC61 turbo. What else is needed for a complete turbo kit? Who manufactures the large intercoolers?

Thanks

I hope your block is sleeved.

Contact Tony from Import-Palace.com. He'll get you a great kit put together.

the amount of boost you will have to be running for that setup to make 400 whp is gonna be in the lower to mid twenties. if the motor is built strong enough to handle it, and your turbo is big enough, you just gotta crank it up really.. but there is a lot more to it than i have the knowledge for. goodluck, and i hope you get it

umm lots, I don't know if you just dropped the comprssion or if you put forged rods/pistons but here you go...
Probably cryo treated crank, forged rods/pistons, A darton or aebs sleeve, Manifold, 3" or larger downpipe (good luck getting that to fit...) Coolant lines and coolant line taps, oil lines, oil line tap, oil pan tap, vacuum lines, some sort of Fuel management, ignition, probably an ignition retard, I'd reccomend an electronic boost controller so you aren't running 20psi all the time, All turbo and intercooler piping, and an intercooler, wastegate, and to make 400WHP I'd replace the intake manifold and Port and polish the head, as well as get some cams, do the head work (titanium valvesprings retainers stainless valves etc.) then your looking at bulletproofing the transmission axles and an lsd to get it to the ground. trying to think of anything else.... That's how I'd do it, and that's if you don't get into al;l the safety equiptment needed to run it at the track, My advice do it step by step collect all your parts and then boost 35 or 40psi

Oh and look into the GT28RS or the GT30R Garrett turbos cause you arn't gonna spool up for a while

This isn't a Cummins diesed now man. Really 35-40 psi?! You could litterally blow the spark plug out of the head with that much cylinder pressure, that is if the weakest things don't give first, rings, head gasket, etc. Seriously though to run a psi like that on an H22 is unheard of. The car would be totally unstreetable at best.

LOL 40 psi. accordsir did 400 whp with +-20 psi.

[ace22]

unstreetable yes, even twenty pounds is on the verge of unstreetable, if your looking for reliability 20psi isn't the way to go any way. We are running 20psi on an h22 prelude and we have already had to rebuild the turbo twice and replace more gaskets due to heat than i can even count, we hope to run 30 psi by the end of '05 .
Spark plugs blowing out, now thats what i am talking about, that would be one impressive sight, Especially when running custom threads, we'll se if your prediction comes true, we expect to have "the lude" running around 40 by mid year 06.

Never said it would take 40psi to do 400hp read the thread...

sleeved block, upgrade oil pump gear and system(most forgot about system when boosting), One hell of a fuel system, and engine managment.

[kamaccord]

What turbo are you using?

[Accord R33]

dont forget to pray to the "Please dont let my engine disintegrate from to much boost" gods

[kamaccord]

I don't believe I'l have to run as much boost for 400 HP as many people think. I like your car

Peace

[hybrid90accord]

12-16psi with a nitrous express N-tercooler kit=400ish!

[kamaccord]

Thats around the amount of boost I would expect. Thats far less than those assuming 30 to 40 psi.

[Fearit22]

I'd say a little less boost and a 75-100 shot of nitrous would be a little easier on the turbo and a couple other parts possibly. I'm not really sure if it would make the pressure any lower or not though. Pressure and temperature are directly related so it would just depends on how much nitrous would raise the temperature compared to an extra 10 lbs of boost or so....
