Ebay idk of quality but I bought one and it looked just like the parts I pulled out.

Eye ball they are the same. I didn't mic them and took like 2 days to get to me.

I would take the intake hose of the turbo and check the turbine shaft play for sure! Especially since you said there were some turbo oil feed line issues. And make sure your intercooler hoses and clamps are on tight, no tears/ cracks. You may have a boost leak. Listen to any whining or any whistling sounds when youre boosting. Any sounds of pressure leaks. Your BOV also may be the problem, try to take it of and do a test run. I would start with that.

The shaft does have lil play but spin freely, no chip on both compressor side and exhaust side . also I'm pretty sure there is no leak according to my boost gauge (idle at-20).however it does have whinning sound when boosting ....back to the ebay turbo rebuild kit , not bad for a $60 rebuild kit, lets c how long it could last :D

I measured ever part. They are all perfect. So in the future I will happily buy my turbo parts from eBay user (turbos_r_us)

If you want to rebuild it you need a way of measuring.

As far as balancing the rule of thumb is to mark it. The turbo is very easy to assemble I think a 5 year could do it. Hardest part is the clips lol.

Anyways you need to disassemble your turbo before ordering parts. They machine/bore turbos @ .005, .010, .015 so you need to know where you are first before ordering. Ebay kit is stock unless specified.


Basically remove a old bearing and measure it. If stock it will measure .625 when you measure the turbo housing you should get .627

Now when you measure the inside of the bearing you should get .394 and when you measure the shaft should get .392

After you have your measurements if you want post them so you can buy with confidence.

But now that you have your measurements and know where you are look for scratches. Use your fingernail on the shaft if u can feel it....it needs attention. If it's smooth all the way it's perfect. For the housing use like a ink pin or a tooth pick.

If it'd rough n has issues let me know and I'll tell you how to go about fixing it without a arm n a leg. Any machine shop can do it they just don't know the specs.
