Heat wrap/turbo blanket for twins?
Is there a thermo blanket or a product (heat wrap) for our stock twins? It seems like there should be a better way to keep heat out of the engine bay.
I did a search for heat wrap but only came up with Downpipes...
Edit: This thread talks a wee bit about people wanting one for the stock twins, any updates or ?? https://www.rx7club.com/showthread.p...hlight=blanket

I've never been a fan of exhaust wrap. It's a messy (and itchy) way to tackle the problem.
There are some ceramic coatings that can take the temps. You can have the manifold and turbine housings coated - I'm pretty sure Rich (GoodfellaFD3S) has some coatings that can do the trick.

The twins are packed in so tight I just can't see any way to wrap it with them on the car. Or do any other form of blanketing.

I just read a thread the other day here in the forum (somewhere, I forget where, maybe Mr. Links knows) where an FD had an underhood fire due to a small oil leak soaking the turbo blanket, and then the blanket caught fire.
Lesson: if you have a turbo blanket, it could hide a small oil leak, and the blanket should be removed periodically to check for leaks. Easy enough on a single, pretty hard with twins.

Sure you can insulate the twins + exhaust manifold, and it works great. I made blankets for my BNR's using refractory insulation blanket for the exhaust manifold and turbos and fixed it inside of the oem heatshields. Additionally, I also lined other clearance challenged heatshields (& turbo lines) with a thinner wrap type insulation (similar to the downpipe wrap), about 1/16 thick. See attached pics.
This thermal management has been in use now 3yrs, 30k+ miles and the effort was very worthwhile. There have been no know ill effects so far. Please note that I have no fluid leaks, but I do think its a valid point to avoid saturating any insulating material in the interest of safety.
NOTE: While ceramic coatings have their place, refractory insulation is a much, much more efficient and effective way to insulate than any ceramic (barrier) coating; hence blankets are my first choice for this application.

Pettit Racing has this:

and Turblown.net has a LIM heat blanket. I have the 20B version:

Which can stay and then you add the extra heat protection.
I don't know if the Pettit kit works but somewhere I recall Pettit posted up nice decreases in AITs. I can attest to the value of the turblown LIM heat blanket. Keeps the heat from the turbo away from the engine.

I did exactly the same thing using the Thermo-Tec aluminized 1500 degrees sheet with the OEM heatshield. It has held up fine over 6 years and 29K. I tried lining up the area on the fender opposite from the downpipe but engine movement caused the downpipe to tear apart the lining on the fender wall. What I have done now is to partially wrap the downpipe as it comes out the turbos to the area near the cat.
