Just go for it. The only thing you may run into is some h22 have a seconder intake runner like the gsr the f22 dose not so you ether have to run without it ditch the intake or swap to an h22 ecu and wire it in. You may consider swapping the ecu because the f22 ecu may have a hard time running the h22 perfect but should do the job to an extent. If it was my car I would use an h22 ecu.
obd1? obd2? Some times obd stuff gets in the way. Do all your research.
