The engine is quite a right fit, the master cylinder sits very close the cam sensor and rubs the wires through. If you use the 2.2 gearbox the subframe needs modifying for the diff to clear, and you will probably need custom shafts. You would also need to sort out something for the hydraulic clutch and cable gearchange.
Also on the phase 1 parts Ofthe bonnet frame need cutting out to clear the inlet manifold, not sure if this will be the same on later ones.
At the moment I could really say weather it's worth it as still in the process of getting the mapping sorted. But when done it should be good for over 200hp
