I am swaping a 2000 JDM ITR B18C5 into my 94 Si, the motor will be in my hands in two weeks. It is comming with entire harness intact and 2000 ITR OB2 ecu. Is it best to use this ecu or an OB1 ecu from a gsr or VTEC Del Sol? Do I need new hubs I don't know if the JDM ITR axles fit the 94 Si hub assembly? If not does it fit a GSR spindle? I hope it does as the origal axle have only 10K miles on them. I apreciate any help, My last swap involved several nights of overconsuming alcahol due to wiring issues. I don't want to do that again.
