07 Speed 3

Almost finished porting my spare intake manifold. Got all the ports done and now just need to work on the throttle body inlet.

Intake Manifold before porting with VTCS butterflies still in



With the VTCS flaps removed there is a large ridge inside the ports



Grinding away the large hump in cylinder one where the end of the VTCS shaft goes



After this I finally got some marking compound and really got to work





And now all that's left is the inlet. As you can see they drilled the inlet off center.
