ok so i saved up and got myself a JDM 97 GSR Changeover and its a OBD2 woohoo, i had it installed (no garage) and after that i find out that jap emissions are diff. so its a OBD2 that wont pass US emissions. So my question is if i have a USDM Head & ECU put on a JDM block what other sensors would have to be add/replace

thanks for the help

I'm pretty sure all you need is the IM and ECU. So you should be ok.

I know it says ITR, but use a USDM GSR manifold and the instructions are the same.

Well from what i know the JDM blocks dont have some sensor that the USDM does. I forgot what its called though. And something about the pump.

Should be just intake manifold, and you should be able to find that other sensor. What year is your civic?

JDM motors do not have the Ckf sensor , its the sensor that is bolted to the oil pump on OBD2 engines
