I bought the kit(sts w/ gt-67) used w/ 3K miles I think and just had it installed.. ...... everything is on and was ready to do a dyno run when its spits oil out the exhaust... the garage says ill prolly need the turbo rebuilt.... but is there something i should know or ask them before they tell me it needs rebuilt?? i dont want ripped off...

aside from that... sts said with the gt-67 and a stock 02 ss my car should put out close to 500.... what will i be looking at hp wise? its an a4...

I wouldnt say turbo rebuild yet. You may need a oil restrictor in your oil feed line. Is your return oil pump working also?

back when i had my custom rear mount i had to put a check valve in the feed line. Check what hunter mentioned above and you should be good. Turbo rebuild should be the last option i think. good luck

as far as i know the return oil pump is working... as i was tracking down where my kit came from... its been through 4 owners.... so... i've already spent 600 bucks on parts that it was suppose to come with but didnt...

Thats what sucks about buying kits second hand. I had to spend over 1800 on custom and extra parts on my TTI kit that i purchased off a guy that said that every thing was there. I agree with the check valve it would be the first place i would start since it is far cheaper then a rebuild. If that does not fix your problem then i would consider a rebuild or replacement. For horse power a lot depends on your set up and how much boost you are running. I dont know a hole lot about the STS kits but with injectors and a good tune i would say 500 should be in your reach. A good cooling system (air to air intercooler or chemical cooler) might also be a good upgrade if you dont have them already.

Never crossed your mind as to why it's been through 4 owners with only 3k miles? I'll bet they had the say issues as you and got tired of it and sold it. Scavenge pump set-ups are a PITA. First check the drain line/pump and ensure thats working properly. Possibly replace the return line with clear line, i found some at Home Depot to use temp. so i could watch the oil flow. After that possibly try a restrictor in the feed line. If not, oil it probably just blowing through your turbo in need of a rebuild. Best of luck getting it squared away.

As for power, all depends on how much boost it sees. If it ends up around 8 psi, i would say you'll be pretty close to 500 on a dynojet through your A4.

check out the STS threads, lots of info on fixing this problem. Are you sure the pump is running? I had a problem where the wire you tap into from the pcm didn't have enough power to always trigger the relay.

get a new check valve and see if that fixes it

+1 on that and also put In a restrictor.I also run my pump on high all the time.

Also make sure your return line from the turbo to the pump has the loop like a P trap exactly like in the manual.

Replace both the wire harness relays. +2 on the check valve, The reason I say replace the relays they collect water inside them and go in and out even when driving the car.
