If not JE then what?

JE's not good on boost? I dont know who you have been speaking to but I would stop talking to that person. JE is one of the better manufactures on the market today and Forged pistons are well suited for the job of boost. If you need help building the motor I work at a 39,000sq foot engine builder in Inverness, Fl not too far from you and you can ship real easy if you didnt want to take the drive. Give me a call...

see thats what i thought, but my pistons are less then 600 miles old and already under mid boost 10-15lbs it will start smoking until i downshift and let off the boost.... i know it not the valves because i just had them redone less then 3 months ago when i bought all stainless and titanium upper end parts any ideas

Oil rings have gone bad.
My compression rings from JE never seated properly. So im stuck with boost leaking into my crankcase.... yay.

JE does not have my vote as far as high quality.
600 miles and 15psi is well... not something I would run until they're broken in.
What is your setup? Your turbo seals could also be the issue.

Sounds like a pretty good setup.

Sorry to hear that its smoking on you though. Assuming nothing is majorly fucked up I would also be guessing its improperly seated rings or turbo seals.

There is also the possibility that it may not be oil smoke if your fuel setup may be going crazy rich under boost which could make your engine appear to be smoking.

well i know for a fact its oil because the smoke is white...but i just had the turbo fully rebuilt (all bearings, seals and shaft) and balanced... so i think its got to be the pistons...

You're running a motor under boost before your rings seated thats your problem..Was the motor overly rich during the break in process,how did you break in the motor?How soon did you boost on it?
