Hello people. I finally got my car this Saturday! It's a 97 GS with a Hahn Stage 5 turbo kit.

You might ask, why the dissapointment? The S20G has broken seals :( I can see the oil comming out of the air inlet. Its broken seals or too much oil preassure that is forcing the oil out. The smoke is just terrible.

Has anyone had this problem with Hahn turbos? Anyway, I left the car at the shop. Besides the smoke, it runs great at 15psi! I loved it for a couple of miles. Any help or comments are greatly appreciated.

Who's car was it that you bought? high oil-pressure shouldnt make it leak there though....

1997 Silver RS
Wiseco 8.8:1 Pistons(back to low compression!)
Eagle Rods
T3/T4 Turbo
Custom FMIC
Greddy Exhaust
440's
Most current 1/8th mile time: 8.3@90mph 2.015 60'(Nitto Drag radials, i suck)

Just curious but what all do you have that you call Stage 5?? and the car wasnt smoking or leaking when you bought it? All of a sudden it just started leaking and smoking? damn. Doesnt make much sense...

Stage V. Maybe Stage 4. LOL. I bought the engine and turbo kit from Greg from this forum about three months ago. I upgraded the turbo from a S16G to a S20G. This is what I have installed in the car. I'was reading Maximum Boost on the section where it mentions oil flow and preassure requirements. One of the paragraphs mention exactly what my car is suffering from. It suggested that the oil preassure might be too high. Anyway, I tested it for like 10 minutes before it started to smoke. Any suggestions?

yo u got me soo scurred! whe i saw the subject "what a dissapointment". i thought u was talking about the car with the stage 5 itself! phew! now i can keep going.

No, the setup is great. I've never driven a turbo car before. I loved it, the sounds of the BOV, everything is great!! I'm going to send this turbo to HRC so they can inspect it or something. Don't worry about it. Later

welcome to the world of high maintiance :7

I'm glad Greg's car is still around, especially when it's owned by someone on this forum. As for the turbo, I wouldn't send it back yet. Call HRC tech support first. They will help you diagnose the problem. When you said oil is coming out of the air inlet, do you mean that there's oil in the intake pipe? If so, then you are probably right about the broken seal. Another thing to check is the oil inlet. When I removed and reinstalled my turbo, I used teflon paste on the threads and it just burned, causing oil to leak from there and running down the sides. I currently use teflon tape and that seem to have solved the problem. Maybe that's not the case with your car, but it's something else to check. Call HRC first.
