I can tell this is going to be a big learning game...I'm sure I'll catch the curve, but I guess it's a different way of thinking: gas vs diesel... (for turbos I mean).

Ok, so here are a few more questions. I've seen guys wrap their headers in that heat insulating tape/gauze and say that it helps turbo spool because it's not letting heat escape...i.e. less heat lost to the compressor side so more efficiency.

Also, since I'm going to be building the motor before putting it in the vehicle (remember I'm the moron who wants to put a little bitty 617 in my Range Rover)...what is a realistic boost level that you should see on these for long term use that will not harm the internals (pistons/rings)...

Forced Induction, are you from the superturbodiesel site?
