im curently putting a 90 spec rs turbo engine into my mk5 escort but im having alot of problems with the gearbox as the standard gearbox i cant get a front mount for so i tried a desiel box and the shaft that comes out the gearbox is bigger on the desiel box than on the turbo 1 so it wont fit in the clutch or fly wheel

does anyone have any ideas what i could try next??

cheers
