    I would GUESS you can order a factory oil cooler line from an HD or something, that would come with the plate/line you need. Then just route the line to the turbo instead of to the radiator...
    blown transmissions are about as useful as 97% of the guys on this forum

    Just remove the flange above the oil filter and buy a 1/8" to -3an (jic) 45deg fitting.

    Also, with your setup and power you're looking for, get a Transgo Shiftkit and vette servo, mine live for a long time with 5psi.
    As soon as I turned it up to 10psi, the output shaft broke.

    yep were pretty much done with the install. we did remove the flange and tap it with a npt fitting and worked great. only things we have left is the booster T fitting, a few hoses. and need to buy about 3 ft of pipping.

    one question since my kit does not have the buzzer for the oil pump, can i run the two wires for the pressure switch on the oil pump to a light or something to tell me if it fails?

    Anything less than 10 psi is boring. with that in mind, get you a built tranny with the billit input and output shafts. Get you a good posi unit in the rear end.
    60# injectors. You will also want an sd tune, because when it rains it will suck up moisture, when your in boost. Once the maf gets wet it will run rough until it drys out.

    If your oil pump is really noisy, it's a good bet it is on it's last leg. I spoke to the STS tech guy and he said the oil pump will be noisy when it's about to go. Check the tailpipe for oil. If you find any, there will be oil in the intake pipes as well. This pump was recommended to me as a replacement.

    Check your intake pipes for oil. If there is any, it will cause the MAF to read less air. If you get it early, you can clean it and it will still work fine. Happened to me
