    Looks like NA extractors will form the base to my single turbo manifold

    So i may have sorted the smoking on deceleration issue. I installed a new turbosmart OPR40 oil pressure regulator and the car didnt smoke at all on a test drive.

    Heres a pic of my standalone oiling setup. 1 pump to feed oil pressure to the turbo with the OPR40, overpressure bleed line to top of the reservoir and another pump after the turbo drain to return oil to the reservoir. Next step is to do a road tune and get the fueling lined out and we will go from there.

    Ok so the smoke is still there but not nearly as much as before. There still seems to be some in the housing from before so we are going to clean it all out and re-mount my lower pump to be lower than the turbo.

    Seems the stock TT pump is dead. Anything over 4000RPM and 7psi leans out. Left the car with my cousin and hes wired in my walbro 480 fuel pump and will re mount the lower scavenge pump.

    Walbro fuel pump is in, no more leaning out. Drove the car around a bit last week, its very fascinating how quickly the 42R can be forced to come on. I'm going to experiment with bypass valves and a smaller big turbo in the future, my current setup is dropping the small turbos boost by whatever the 42R runs.

    So at 15psi total boost if the 42R runs 5psi the remaining 10 is fed by the stockers. I'll be aiming to run more boost out of the 42R and have the stockers drop to 2-4psi. Enough for them to contribute and not be "in the way" like they would if i dropped them completely.

    I have had this setup at 26psi without touching the 42Rs wastegate pressure.
