heat wrap for up pipes

[zpd307]

has anyone wrapped their up pipes with heat wrap? i will be putting in new donuts soon and figured since the pipes would be out that i would wrap them up and keep more heat in for the turbo. it looks like it would be a little tight since it doesnt look like there is much room between the pipes and the block. i know keeping in all the heat will make the turbo work better. i wrapped the crossover pipe with heat tape on my old 90 that i turbo'd. just wondering if any had done this....

the turbo doesnt need any more heat than its already getting! unless you want to run the chance of a turbo failure.

i have to disagree, i have read many articles on better performance from the turbo after insulating all the exhaust components. one article highlighted the use of some special insulating metal shields and proven dyno and specific tests that showed how much better it worked. to put on the shields would have cost several hundreds of dollars, several years ago. as i said earlier, i wrapped the crossover pipe on my 90, which i turbo'd with a factory 94 turbo, with good reults. mainly a quicker spooling turbo.....

I am somewhat new to the Diesel world, but with anything turbo'd it has always been what I believe to be common knowledge that Heat kills components...

just did some more current reading on the subject..... think of it as this, what drives the turbo? hot exhaust gases. keeping the heat in the turbo spins the turbine wheel faster, which also expells the gases faster. which reminds me, does anyone know what style of exhaust housing the early 99s had, ie- t3, t3/t4, t6, etc. i see a bunch of different styles for sale, but need to know which style to get.
