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

 

mounts will work

 

sweet anything else that wont work or ill need to know

 

You will need the motor mount of the side of your gsr block, the b20b one is to short and your motor will sit at a weird angle. If you use the gsr ecu, it will throw a code for vtec. If you plan on getting it tuned, find a p28 ecu and get an obd2 to obd1 conversion harness. And just have your tuner turn vtec off so it wont throw any codes. That way if you go b20b/vtec someday all you have to do it turn it back on and you will good to go. Othen than that the swap is straight forward. If you have any questions just PM me, I just did the same swap into my 99 Civic.

The motor mount I'm taking about is the one that blots to side of your block and attaches to your motor mount.

 

thanks

 

jdm b20's dont have the crank fluctuation sensor on the oil pump either. If using obd2 ecu it will throw a cel for this. Either change the pumps or convert to obd1
