problems w/ jdm swap

i put a jdm f20a dohc in my 90 accord and it feels like it needs to be tuned but i cant get any specs or info on it, i know the valve clearences r off but i cant adjust them without the specs also i have my stock computer will this limit the performance. my old engine was 130 hp but had over 200 Ks onit this is a 150hp and im only feeling a little bit more power. any websites or info or if u made the same swap please help.

I'm guessin you got the dohc NON- V-tec rite? I believe you can get the ecu from a h23 prelude but then you gonna have to convert it to obd1. Check your timing also. Usually they're a lil bit off. I'm not too sure about the valve adjustment. Maybe you can use the h23 specs. You can try emailing the guys from www.h22a.org to see if they can help. Sorry i couldnt be much help.
