Doing swap> 4thgen or 5th gen H22a

Should i get the 4th gen h22 or 5thgen? 5th gen will probably have less milege but somebody said something about the ecu not allowing somethin..cant remember :eek7:

depends on what your swapping it into

OBD1 h22=93-95
OBD2 h22=96-01

pick whichever will suit your needs better.

imswappin it into a 92 prelude si

get an OBD1 - 93-95 h22a; out of a 4th gen.

get a vtec h22a4 from a 97-01 and swap in an odb-I ecu

i have to use the odb1 ecu? Why wont the obd2 ecu work?

depending on which h22 you swap, you will need to get the corresponding ecu.

The OBD1 ecu is coded as p13
The OBD2 ecu is coded as p5m

a 93-95 h22 is OBD1, and you can only use an OBD1 ecu on it.

a 96-01 h22 is OBD2, and you initially must use an OBD2 ECU, which tends to detune itself for emissions control; but can be converted to OBD1 if you buy the jumper/harness+OBD1 ECU.

Really...it detunes it self :( So if i buy a 96+ h22 and get the obd1 ecu. I can get a harness that converts it?

yes.

how or where in the hell do you find a harness to convert from h22a4 to p13? Because this engine may be an option for my future swap and i dont really wanna deal with the detuning crap or learning to use hondata to get around all that any time real soon.
