well if i ever want to change the head on my car to a gsr or type r how would i do with a obd o wireharness. i have a zydne ecu. i know the type r and gsr are either obd1- 2. do i have the rig it so the obd 0 disturbor fit on the p72 or p73 head.

 

That might be better asked in the Tech section.

If the dizzy fits, then I wouldn't realyl see a problem with it.

Depending on if it's an Si or not, you'll have to deal with the TDC and CYP sensors, but other than that..

 

I can prolly drop you a GSR/ITR map for your Zdyne if you need it.

 

well ef9 i do have a 91 si. and is it possible to do it. hey jeff how did he do it. he has a gsr head on a ls well now a crv block. with a obd 0 harness. i think he still has a zydne right.
