Ok... at 210,000 the engine is getting a bit tired. I'm thinking of either rebuilding the factory motor or swapping in a 170bhp EG SiR engine. I want to keep the car looking right, so no B18 etc, it has to be a B16.
Question is, will I have to change the ECU and harness and will the EG B16 use my factory mounts and mate up to the Y1 tranny? I'm pretty sure I'll need the ECU, but am not sure if it will plug straight into my harness. Also, I have 2 O2 sensors in my exhaust - do the EGs run this?
Any help would be appreciated.
Cheers
