I bought the wrap from Summit, and am curious as to whether or not I should take the steel lines off the turbo and cut holes for them in the tape, or if I should just wrap them all. It's been so long since I've seen what the factory shield looked like, I don't recall what I should do. I assume that leaving the coolant lines and oil lines open would help them cool faster? What do you guys think. I have the turbo out right now, so it's not much more of a project to do it that way. Any comments?
Hi I'm doing a total rebuild of my engine bay and have the original heat wraps. I will be using the Summit 2" wrap and stainless ties. The oil + coolant lines are not covered, in fact the front part of the turbo covering stops at the valley there where these lines are. I would suggest the adhesive backed foil tape for the 2 fuel lines running over this area also.
No, you should wrap the turbine houseing with one piece and the compressor housing with another. Its intended to draw tight around the housing, not around the whole turbo. Its hard to explain, but the wires you thread through the edges will end up circling the center section and the downpipe on the back. Then I would use another piece and wrap the unbraided part of the downpipe.

also make sure you wrap super tight and do not wrap regular exhaust pipe because over time it will have condensation between wrap and metal and rust overtime. Your manifold and turbo are fine.
Leave it naked for everyone to see! :twisted: You dont even need turbo wrap. I just used heat shielding on everything around the turbo. The powermaster III already has that aluminum shield. You can get another one like it in a wrecking yard off an old olds quad 442 header or make one out of stainless sheetmetal and place it on the side of the turbo to shield 90% of the things you need to shield(battery, vacuum lines, plastic parts). Then Use orange silicone tubing with fiberglass lining(same stuff used on ignition wires near a header) for the fuel lines( disconnect fuel lines and take off the hold down clamp, slide on the tubing all the way up and over the turbo on the delivery and return line). Then cut some tubing open (lengthwise) and zip tie a piece on thr underside of the intake pipe and make it too long so it has a flap that goes all the way under the throttle body shielding it from heat. My theory is it is never good to hold in heat if you want your motor oil (not to mention turbo) to not burn up.
