engine fitment
 

Hi all does anyone know how easy it is to fit jdm hawk bottom end with version4 heads into version 5 car?
can i keep version 4 manifold with my version 5 engine wiring loom? or will the V4 engine loom plug straight in my main loom? or do i have swap loom and manifold to V5 and have some sort of spacers?
Any advice would be great

In short, you need version 5 heads. Otherwise its a fair amount of work.

haha i was thinkin that maybe the case cheers matey
