I started my 1jz project a while ago and need a couple of parts before putting it back together. I don't want to put the stock turbos back on because they were such a pain in the butt to take off but I don't completely understand what all I need for a turbo exhaust. I know I need a manifold and turbo but how exactly do wastgates and blowoff valves work? And also what would be my best bet for wiring, I was thinking of going with 1JZ Wiring Harness MA70 on 935motorsports.com?
