shit might as well do a turbo upgrade at the same time. kill 3 birds with one stone.
Haven't seen the instructions. Is there really that much overlap? Was going to do this in separate phases just due to up front cost, but if it's going to save a bunch of time in labor costs, I might just have to rethink things.
You need to get the manifold out to access the HPFPs, and then the Vac Pump below them. It seems you need a LPFP to run higher than E40. Might as well be one big build.
