That's far more reasonable than the numbers that I have heard for the OSG deal. I am interested, but I am in the very beginning of my money pit and nowhere close to needing to start the engine guild at this point. But it's nice to know it will be available when I am ready. I can't wait to see the numbers one a max effort turbo build lays down!

So, I guess I finally worked up the nerve to ask: How much is this going to cost me? Or is it still at the "If you have to ask what it costs, you can't afford it" phase? I dream about two "Baby" EFR turbos on this setup. I am just happy someone is giving OSG some competition, you've done an awesome job Derek!

That's about as nice as you will see from Garrett, it'll do just fine. If it were on a billet comp wheel, then I would worry.

The side gap should look more like .0015-.004 range, that shaft shows a ton of wear. I would imagine that the compressor side of that unit is in pretty sad shape as well, it may be time to make a move to a new turbo. Check your PM's.

Your turbine side piston ring (oil control) has probably collapsed. You should be able to find a rebuild kit for less than $50 as long as there is no damage to the pistong ring groove or the piston ring step on the center housing. PM me if you have any turbo disassembley or re-assembly questions, I'll be happy to walk you through it. Be sure to pay careful attention to the orientation of the wheels and balancing cuts on the compressor nut. This can cause noise and/or bearing issues after re-assembly. Also the compressor nut is probably a left hand thread, so righty tighty, lefty loosy isn't always correct when it comes to turbo chargers. EDIT: I just re-read the thread and saw where you had already re-built the turbo. Did you measure the gaps on the piston ring on the shaft (side clearance) or the end gap (while the piston ring is not on the shaft and pushed into the bore of the center housing? Start with those measurements and I can probably give you some guidance.
