#170957 i think you need the P13 ecu or 92-95 Prelude Vtec (h22 model) ecu

#171129 h22a4 is the usdm obd-II motor. best bet would be to get a jdm h22 obd-i motor. if you already have the h22a4 you need the p5p ecu. but then you would need to convert your car to obd-II.

If it was me i would get a obd-1 h22. with a p13 ecu

#171770 you can run a p28 just have it chiped and tuned for the h22.. i run a h22a in my sol and run a p28. youll have to convert your harness, not hard just time consuming
