I have a 2.5 06 short block. And the 05 Saab 9-2x Aero 5 speed 2.0l motor.. I am going to do the build in the spring...
My question is. I planned on using most of my original parts. I am using the ej205 heads from my car. And changing to the 6 speed transmission with STI cluster. I was hoping to do new STI head gaskets and timing belt kit ect.. The block has the oil pan and oil pump and water pump on it.
I was hoping I do not need to change ECU or wiring harness?? My car is custom tuned at stage1 right now and runs great. Any chance of me not gaining much from doing a hybrid build..
I have a ported polished turbo, cold air intake w/inlet hose, Aluminium radiator, cat back exhaust. Or do I do an uppipe only and tune to stage2
Thanks for the help..
