Yep that looks like the one. If its a comp housing leak to atmosphere break out the copper rtv and see if it works.

Now don't take this as gospel since I dont play with BBs very often, but I believe that "oil restrictor" piece is what holds in the outer bearing race. To remove I think you thread a bolt into it and pretty much slide hammer it out. Remember to check runout on the turbine shaft after any housing contact. A guess on tolerance would be around .0005 inch or .0127 metric.

How many miles are on this turbo. I'm just curious as to the conditions for its failure. You know lack of oil, too much oil, ups dropped it (a lot), or maybe a noticeable defect that slipped past QC. If you find anything interesting please post a picture.

I personally would stay away from chinese bearings on something that spins so fast. Give garrett a call and see what they can do for you. Also maybe look on www.himni-racing.com they have everything you need and may do exchanges.

The oil seal between the chra and compressor back plate is all that keeps the boost in. If your chra and housings are toast its cheaper just to buy a new garrett with a warranty. Knockoff compressor wheels aren't worth it. Sometimes they're heavier to make them strong enough because of inferior alloys, and low quality control (think turbine overspeed burst).

I used to get compressor surge during cruise with the bosch valve so I mounted a Tial atmospheric and get much less chatter. They also make a nice recirculating valve. I agree the stock evo valves are pretty good, but if you feel the need for adjustability there are many quality aftermarket valves to choose from.

The oetiker clamps are nice but are not necessary. You can get specified fuel injection line clamps that don't mess up the hose too bad. Also as cheap insurance I would change the hoses, but only use 100psi hose it's much more robust. As for the tires look up the rpm of your current set and compare it to the ones in question. An example would be a 205/65-15 does about 820 revolutions per mile.

Thanks for the welcome I've been lurking for awhile. Mines an 86, I bought it from Bryan Cohn last year and have been doing mods ever since. I'm located in southern MD.

I recently replaced the in tank primer pump on my turbo with one from a 1990 VW Corrado. Pump is made by VDO and was a direct replacement.
