Some time in the near-ish future, I'm going to set a primary beside my HX35. I have the turbos and I'm considering picking up a spare manifold, so I thought about doing some porting. I also thought I'd wallow out the hole for the gate in the HX35.
I think it's more of a time than money thing. So where and how much do I take off? Also what bit should I use?
Thanks in advance.
