Started thismorning removing manifold studs. 2 were stripped so it took 1hour or so to get them out. 1 I just put loktite on and the other with vice grips and a 6mm ring spanner forcefully.

Once they were out all new studs and single turbo and exhaust on and started it. Its been sitting for 2 months or so with e85 but it started instantly.

Video of start up with 4 inch straight pipe exhaust.
Cartidge not in just to blow out anything in the manifold and rear housing.
