ok im trying to put a b20b with b16 hydro trans in my 97 gsr and i kno it will work bc it is obd2 and im changing the intake mani. to an ls and getting and ls ecu bc i heard gsr ecu will throw codes but im not sure if my mounts from my gsr will fit and if i need to kno anything else lmk thanks

 

so you want to know if an ls ecu will fit your gsr? It will plug in as long as it's an obd2a ecu.

 

thanx though

 

Yes they will.

 

You will need to change the driver side mount on the B20 block...then all of the mounts from the GSR will work. Good luck!
