Blown 7A redemption, attemp #2 Options

[Cevax]

Haven't been here in a couple of years but some of you will remember by 7afte turbo project that was a complete failure. Swapped in a 7a and started the the turbo project and blew up in the highway a few days later.

On my first project I didn't do any of the work outside from some wiring. This time this is a true backyard build anyway my goal is 450 on race gas 380+ on pump. 7.4:1 compression with 25 pounds of boost

Anyway I wont update this a lot since its on other forums

Engine is Fully built, only stock part is the throttle body, wont go into details because non of you really care

Car does no run yet
Stuff missing

New exhaust manifold
Standalone EMS
New FMIC

Hmm figure I update this. Ok so yesterday I began to try and figure out why my car smokes like a train after it runs for a few minutes. I know since the motor has seen no mileage the rings aren't seated but damn, its a lot of smoke. Pulled the turbo and all behold the charge pipes are full of oil, my exhaust has oil seeping right through it. That explains some of the smoke, now my turbo has no mileage but I did start the car with it installed a few times and oil pressure is well over 100 psi at 3500 rpm. Pretty sure that killed it, anyway added a few restrictors and began to rethink my return since my scavenge pump should handle that oil pressure no problem. So something is wrong.

Anyway instead of trying to eliminate things I dumped my whole return setup, do it again and if it still smokes try to rebuild the turbo before Thursday before my dyno appointment. First thing was getting rid of those dumb, overpriced bull**** npt fittings and braided hoses. Took of the bung on the oil pan and added a barb fitting. Then it was the difficult task of relocating the scavenge pump. Now this was a problem, I have very little space on my engine bay and the pump is big and heavy, it cant be to far from the turbo otherwise it wont prime well. While I was trying to figure that out I had to take my intercooler off.... for the 1000th time so I put the pump on the back burner and try to mount the damn cooler permanently. The cooler wasn't going on, so I decided to pick up a crash bar which unbeknown to me, would be a 5 hour ordeal. Called around and nobody had it, so decided to go to a junkyard where they wanted 75 dollars for it. Then it was 40 if I pull it, but I couldn't pull it because the bolts are rusted, they have to be cut. Then after all that bull**** they said its too much work for 40 dollars, so I guess they wanted more money. I called one of the places I called earlier in the day, worded my question differently and 3 hours stuck in Boston traffic and 18 dollars later I had the crash bar. So 40-75 at the junkyard and 18 dollars brand new at a parts store... yea how the hell does that work. Anyway, I put the bar on and the cooler now goes how it is supposed to. The good things is that the crash bar gives me a new place where I can put the pump. It sits level right at the turbo, it only has to go up a little bit to go back up to the oil pan, which should make things a lot better. Now I took these pics with a damn cellphone but I will take slr ones tomorrow maybe. Wanted to drive it today but hopefully I can finish this up tommorow
