There is a civic forum there that has most of this information FAQ'ed.

There is also a Prelude forum... Since the H22A is usually used in a Prelude.

What type of CAT are you using? Do you have exhaust obstructions or a bad muffler?

Do you have access to a scan tool that can take freeze frame date on the unit warms up? If so, post that information:

ECT
IAT
MAP
TPS
OS1
OS2 (if applicable)
Spark Advance at Idle with A/C and everything turned off.

You could have the timing belt off by a tooth...

What did you do with the EGR system?

Did you adjust the valves properly?
