Let me ask a retarded question. Is your fan definately blowing in towards the motor when on and the blade is on the right way? I reversed mine inadvertantly on my last car and didnt check it when I installed it. The car ran crazy hot. I corrected it after the first ride out with it and it was perfect.

 

How close to your rad is your exhaust?

 

DO a leakdown!

 

Don't give up!!

 

It was kinda close...but my fmic was pressed right up against the rad. I took the entire turbo off and just slapped a gsr mani on there for the time being. Took it for a drive and drove for around 45 minutes...no overheating. I even took it to redline in 4th, and the guage never even hit the half-way mark...just a hair below it. Granted the car was much slower than earlier today, but it was such a joy to drive. Now if I can get the topend of the rpm range to breathe a little better, then it won't be too bad. B16 auto cams blow. :P

 

Your headbolts are stretched...your getting head lift while in boost. That would be my appraisal. Exhaust is slipping into you water jackets/coolant passages. How much boost again?

 

It was at a max of 10psi for one day, then I lowered it back to 8. It did it regardless of whether it was at 10psi or 4. It's a good possability though, this is the 4th turbo setup on this particular stock b16. It's seen 17psi, and it's also seen the 300hp threshold for a brief moment, so more than likely it's getting tired.

 

Heatwrap your exhaust, problem solved. Mine was the same.

 

doesn't sound like ambient heat is causing this though Minor. If it saw 17 psi I hope you have arp headstuds?!?

 

Exhaust was heat-wrapped on the dp on back.Nope...all stock motor...100% stock It didn't see over 17 for long and it was on a smaller t3. It probably was leaking through the hg under boost, so far all night last night i was beating on it it never overheated once.
