Hey guys I just recently stumbled across a MazdaSpeed set up for $175 it includes ECU, manifold, downpipe, turbo, and also has other hoses and wires. I was not think about boosting my P5 but know I see this for cheap I really want to pick it up. So I'm trying to keep the price down I know I need to buy an intercooler and piping. I just need to know if I need to change any of my engines internals I currently have 140k on the engine and it will be a DD. Any help would be very helpful thanks.
