Not sure what your plans are for the clutch and flywheel setup. if you go to a single mass or lightwhieght flywheel setup then for sure.

Already ahead of you. I just ordered a oil pump but from turner motorsport that is drilled for lock wire. it can be secured around the round holes in the oil pump sprocket. For the clutch, I'm planning on doing a Valeo single mass. It's only a pound or so lighter than the stock single mass. Besides the oil pump nut, do you have any other recommendations to reduce harmonics?
