The campus engine is too high compression, also oil pump isn;t up to job nor is the timing chain tensioner. The valves are smaller and rocker shaft isn't suported as much as a gt one, also cam is diffferent. The throttle body won't fuel for turbo applicaton either
To be hoonest to turbo the engine correctly your be left with a block and crank and thats it from the original engine, everything else will have to be changed to cope with a turbo
