Hey, so I have a V5 STi and the motor spun a bearing and now makes a knocking sound. I was thinking of buying a V7 STi motor and using the Long Block of that and using it in my V5. So I’m wondering if that can be done, like have the V5 intake manifold, wiring looms, sensors, etc... and plug and play onto the V7 STi Long Block. Is this possible?

 

STi uses AVCS heads so personally better to swap your heads and ancillaries onto the new-age short engine
