alright guys, as title say, looking to put 94 gsr in 00 si. i am waiting to get approved for my loan to get this si i been looking at. i am wondering what all will have to be done for me to run my gsr motor in the si. i know itll be a straight drop in, no problem there. but my question is the wiring. i know i can take the injectors, dizzy, stuff like that off the b16 an put on gsr. but since the gsr motor is a obd1, would i run the obd1 gsr ecu or get a obd2 gsr ecu and run that? also i believe ill have to perform the crank sensor trick. so if you can inform me id appriciate it.
