oil return idea

[weejohn]

ok so from what i read the only difference in a turbo block and a ranger n/a block is the oil return hole. if one didn't feel like drilling a hole in their block could you put a hole in the oil pan and weld say brake line to it and run that to the trubo?

Yep. Pretty popular solution.

yes, but brake lines aren't usually 1/2"+ ID. you need to have a big drain line and little feed line.

usually if you can pull the oil pna off you can install a bulkhead fitting with an -AN thread on it so you can get a decent size line going to it.

that's what i did.

Yes - should've read that a little more closely. I didn't catch the 'brake line' part the first time around. Turbo's cycle a surprising amount of oil for no bigger than the inlet hole for the turbo is. You'll need something that can support alot more flow than the skinny metal brake lines.

Weld a decent size fitting in and run substantial line to it. If it can't drain fast enough you're going to end up with a helluva leak. Turbo bearings don't like backpressure.

just tap a hole for 1/2" npt and use a -8an to 1/2" npt adapter

the turbo block is basically the same as a NA block, just has an oil outlet port for the turbo. the main difference between the two is the forged lower compression pistons contained in the turbo block. if you're going to build it up to 300hp, and if you have a regular 2.3 block, I'd just use that and get the other parts you need from the aftermarket or something, you're going to want it to be stout, but stock forged pistons(from a turbo block) should hold up, but they're at the newest 16 years old...
