I wanted to add my 2 cents here... as you can see, earlier in this thread I posted about my fear of the blanket. I've been running a blanket on my TD04 since day one but it was mostly street use.

It turns out, after a couple of lapping sessions, the car started to smoke really bad on idle (blue smoke)... no issue on boost. And when I say really bad, it was really bad.

After a bit of troubleshooting (compression test + leakdown) and with the help of this thread I decided to go ahead and rebuild the turbo in a local shop since the engine was looking okay.

Bearings were black. Overheated. A lot. (I suck, I forgot to take pictures)

Looks like my bearings didn't like lapping session with the blanket on.

No longer smoke on idle since I installed the rebuilt turbo.

Made a heatshield to replace the blanket.

So I learned, blanket for street use. Heatshield for track use.

I like your heat shield, just leave it that way.

Heat shield period. If track car, nothing else over there to fry but maybe the mixing manifold anyway. And hood vents. If I use a blanket at all it will be over the brake and clutch masters. Except not because brake fluid is horrible flammable caustic crap and a spongy blanket of it catching fire right by an open driver's side window is not a fun exit drill. It would probably be slightly worse than dripping brake fluid down the firewall and catching it of the exhaust under the car.

Shield plus vents wins because it does not fry the turbo (helps it) and it protects all the other stuff in there and lowers the overall temps. Evo's are setup this way from the factory.

The rubber heater/coolant hoses will get brittle and fail, too.

Is it a recommended practice to switch to silicone hoses?

I couldn't find a silicone heater hose for the nb. So I just wrapped them in a lava heat wrap.

Ehh, interesting to find this thread.

I currently have my turbo exhaust housing in a PTP Blanket with begi downpipe wrapped in the lava heat wrap.

It DOES cut down on heat, but it also holds in that heat on the turbine. I've noticed I have been leaking oil from my compressor side, not sure on the exhaust but I wouldn't doubt it.

I just put fire sleeve over mine, which did require disconnecting it on one end to slide the sleeve on.

The Mishimoto 94-97 silicone heater hoses fit and work perfectly in an NB, ask me how I know.
