Turbo set up/oiling I been trying to figure out the most logical place to locate the turbo in my ongoing project. I've decided to go with the t76 but im looking for the cheapest place to purchase it. Any ideas???? The next F'n issue is the oil supply to the turbo. I've noticed that the STS system is getting its oil right before the oil filter. Ive also noticed that there scaveging pump for the oil return is boost sensitive (the more boost/vacuum, the pump speeds up on the return line). I think it runs off of vacuum. If I did an underhood install,what would be the most logical location on the motor to tap off of for the oil supply for the turbo. Do you guys think the return line size makes a difference? Any recomendatons??? Im trying to build the least expensive kit/most efficient kit. Everyones help is greatly appriciated.
Thanks, Im off to have another glass of Johnny Blue(xmas gift from the woman)

Get the high pressure supply from the same place. It's about the easiest to get to.
As for the return, use the largest ID hose you can. Something along the lines of a -10 or -12 braided hose (1/2" to 5/8" ID). Place the turbo high enough that you can gravity drain into the pan, front cover, etc. A well placed and large drain line will eliminate alot of headaches. Keep the drain above the oil level in the pan, this will prevent any drainback issues if you have any crankcase pressure.

Right now it has the 8.1 marine injectors in it (~ 40 lb/hr)
It was a little laggy with the stock converter, more so because of the low stall. I'll know more with this turbo when i get the 80 swapped in, I've given up on the 4l60 at this point
I will be going to a GT40 this spring, simply because I know this turbo will not feed my addiction

ok i know its not done yet, but its best to see the oil lines in this pic.
im using stainless steel brades -4 lines for feed off the oil filter and using -12 for return lines. i just tig welded aluminum fittings to the pan and threaded in the steel fittings off the line. turbos seem to be fine when the truck is running. havent gotten the new motor over 3000rpms though...
hope this helps
