That's why I said "The only thing you have to be careful of his how much boost you cram through your intake before you get to the level of having to build up the internals to handle it."

Sleeve the block, forged rods, and better pistons, and you can cram plenty of boost down the H22's hatch. On stock internals, you can safely throw 8 psi at it all day long and still woop some serious ass.

If the motor is properly built from the internals out, there will be no blowing anything to pieces. Check out Jason Whitfields (RAGE Performance) Fully STREET Civic HB that has a well built boosted H22 that puts 850 HP to the pavement through 19" wheels.

 

if i was gonna turbo on stock internals i wouldnt even touch an h22a, i seen too many 320+ whp B series that way....

 

B+boost=320 plus whp... On stock internals

 

Thank you for the reply -- but the car only put down 728 on our dyno

 

id boost the gsr motor over the h22. I hear the h22 has especially weak sleeves prone to cracking in even all motor applications, and above 8psi is really pushing it on that motor. A gsr can take more on the stock internals than an h22(not a ton more, cause its still open sleeved, but a little more), but for an all out, built engine, h22 is obviously the better choice becuase of its size.

 

only 728? I might be missing something?

Actually, the older generations of H22A's (from the 4th gen, 92/93-'96, '92 was only H23A non-VTEC) where a closed deck design from the factory. The 5th gen Prelude body style swtiched to an open deck block like the B-series engines. I still don't know how strong any of them are, I've never boosted one, but I've heard they are pretty stout motors.

 

and why the hell is this dead as thread being brought back to life?
