toxo Have also just bought a phenolic inlet manifold gasket. This acts as a heat insulator between the head and the inlet manifold, preventing heat transfer. This in turn means the inlet manifold and throttlebody should stay cool and not heat up the inlet charge as it travels through.
Heard only good things about them from various forums:thumbup1:
After all this work it will be interesting to see another dyno run. Just to see what a very good service does.

Dan_Turism0 does the '2 engine bay suffer from high heat due to how compact it is?
Yeah and the lack of airflow!! The more work I do on them the more I think they were never designed to have the turbo engine in and it was just plonked in there from the Celica for the hell of it. I've messed about with it from stock a lot as well remember, it has no side fan anymore and it has the chargecooler sat partially over the top of the turbo heat shield which is a bit backwards.

Well there are a lot of them available for Rev1/2 engines as they simply replace the TVIS plate with a big thick Teflon spacer instead. Rev3+ doesn't have that luxury! The only one I've found is a Gizzmo one (yes the EBC people) but they're not rocket science. It's ordered now anyway.
And the main reason I'm doing this is because I did 2 dyno runs a month apart and lost 30bhp! Hopefully once it's done the power should be back up to ~290 like it was before.

All the exhaust path, downpipe, midpipe, manifold and turbo:

This gasket is mangled, you can see the hole around the bottom left stud, and it's broken at the top about 1/3rd of the way across. You can see the split gasket and black soot around it.

Took the actuator and the exhaust housing off. The advice I got for separating the 2 parts was using chisels... it took 5!!

Split the turbo apart today to find more blown gaskets.

Bob found chips in 2 of the compressor blades and some rubbing on the exhaust wheel, so that's new shaft & compressor wheel (they are one piece on these turbos) but the exhaust wheel should balance out. Off to universal turbos for balancing now... and definitely not back for JAE.
