Had to thrash over the last few days to get the new turbos to work. Nothing fit because the Turbonetics frame was different. Turbo mount point was cut and then rewelded. Intercooler had to be cut and welded. Exhaust was a marmon flange on the Bullseye so that was extra tricky, again cut and rewelded. The marmon flange is 3.5" my buddy plasma cut a 3.5" flange with an inside 3" diameter hole the exhaust could be attached to. There's no practical reason to do 3.5" exhaust out the front bumper ... and there's no way in heck i'm fabbing that again.

There were a number of issues found breaking everything down. 6 boost leaks in the A2W, one bolt loose on the up pipe which showed scorching on the gasket, and 4 bad plug wires (3 arced and 1 roasted). Pinched ORB rings on the turbo drains (caused leaks).

I put flanged bolts with pipe dope on threads and copper gasket on the head to stop the 6!!!! boost leaks. So stupid it was manufactured that way. Used the same copper gasket on the up pipes and turbo. The plug wire on the inside of the Firecore plugs got mashed back which caused the arc, the other one was on the header. Happy I ordered an extra set, just incase. New ORBs on the turbo drains. Also had to clearance the oil drains so that there was a tiny air gap.

After everything was together we did some dyno work and got the engine to produce 850whp. WHY NO 1000 HP GREG?!?!?!?! well, the second fuel pump appears to not pull fuel from the tank correctly. Likely a line came off? Doesn't really matter. I can fix it later. I probably wont even turn the power past 600 this year anyway (which is where the first pump stops).

Something I need to change out the twin intake from the car. It stops RPM at 7,000. The twin intake also stops me from easily working on my car... which I apparently need to be able to work on it easily. SO.... I'm going to change the A2W, Plenum and charge tubes to simplify everything. That's not happening for months. I just need to enjoy the car for a little bit. The good news about the changes is that the system fits way better together now and everything aligns on the X pipe, intercooler and turbos.
