To finish off the available bolt ons for this car and get us closer to the 300 HP mark we've turned our attention to the intake manifold.
Basically we are cleaning up the runners, porting, rough polishing, and matching up the air path for improved flow. This is a very time consuming process, about 40-50 hours from start to finish, and none of the internal parts are replaceable. So if this is something you are going to try I would advise picking up a spare manifold, which we have for sale if you can't find one local.
The pics are of a stock manifold and the progress of the top of the ported one.
