How do you tell if the prelude motor is JDM between years?
looking in buying one from a local shop and want to tell the diffrence.

will be going in 97 hatch

 

on the font of the passenger side in the middle it will say h22a instead of h22a1 or h22a4

 

so usdm have numbers after it like usdm b18s. so is all h22a the same no matter what year? no obd diffrence in between years or what?

can yall give me usdm and jdm details.

 

nevermind i found my answers but if i got a h22a motor am i able to use wireing harness from any prelude with vtec lets say from a 93 prelude to mate with a civic? you guys know if the vtec setup the same as wiring a b18 vtec so its just plug and play?

 

Use your Civic wiring harness. Add IAB and knock sensor if using the P13 ecu.

 

so the already setup vtec wire is fine? just redo the sensor and IAB

Yup im pretty sure. If it is a JDM H22 going into a civic, you will either need a new fuel rail or extend your current one. The JDM cars have the fuel inlet in the opposite side.
