A lot of white smoke!

[assa 98gsx]

Went to the track today and on the way down the 1/4mile car was smoking heavily.
Pull the plugs - fine
car idles - fine
compression check - fine 190 across
loss coolant? - NO
loss oil? - YES!
Oil comes out from o2 housing? - Yes
Turbo shaftplay - Too much that I feel like ass that i bought the turbo!
A lot of white smoke - yesx1000

So.... my almighty dsmers! Did I blow my turbo? <-- got a used turbo 3weeks ago from a dsmtuner. Bullseye To4B.

It's definitely coming from the turbo, the question why/how before you slap on a replacement turbo.

1. Excessive shaft play.

2. Excessive oil pressure/volume.

3. Poor oil return capacity.

4. Excessive crankcase pressure.

5. Excessive boost level, possibly combine with boost leak.

Good luck.

okay, my old 16G turbo's exhaust fins were all banged up.. so i decided to replace the turbo with the To4b at a good price from a fellow tuner.
When i got the turbo, i checked the shaftplay, only minimum. I have the oil feed and return kit from bullseye as well.
I had the feed line ran from the oil filter housing just like the stock turbos do.

NOw, this is the catch. I ran 20psi on the track today when it finally gave up and I might have a boost leak somewhere because when I swapped the turbo, the car kept dying going from hi speed to neutral. It might be the high boost level and the boost leak that killed it, but I doubt it since I did boost leak tests after the turbo swap.

Now, I have a choice of going back to the banged up 16G, or another choice of a 50trim turbo. Any suggestions?

Well if you are a frequent track visitor than the 50trim will be the better choice for you in my opinion anyway but, if not than a rebuilt 16g will do you. Also since you have a FMIC a 50trim might be more efficient since it flows more air than that of a 16g.

yeah, i've already have dsmlink 750cc and all the supporting mods for a 50trim turbo. The problem is, i am so afraid to kill another turbo like this. I dont see how the exhaust side piston rings can be shot like that and the exhaust side fins are all chipped off like my old 16G. Makes me think that I have something flew out from the engine that hit the turbo. ( pray not to be the valves!)
Would you buy a used FP3056 or a brand new AGP 49T 50 trim turbo?
