AC meltdown lookin for a place to happen?

FWIW, there WILL be a nice blanket over the turbo. I have been assured by the installer that this will not be a problem. However, i do not believe him.

Why don't you believe him? John has sold more than a few manifolds and I am sure he gets feedback from customers.

Ceramic coat the exh housing and over it with a blanket. You want to do the same to the downpipe.

I suspect you will have no problems on the street. Run the car for 20-30 minutes on the track and it may get hot under that hood.

i assume you are talking about John Volk? the guy who made the manifold ? he did make the manny, but he's not the one installing this setup.

maybe i should clarificate:

basically, the deal is that my installer already 'relocated' my AC lines, and i honestly think they too close to the turbo housing. Actually, i think they might be closer to the turbo now than they were in the stock position. I am a bit worried about the AC lines getting too hot, but have been assured that it won't be a problem. I've never had a turbo car, and I have no idea of the relative effect of a hot turbo housing on AC lines less than 1 inch away. i'd assume it's not good. However, if a turbo blanket will solve the problem, of which i have been assured, then i am willing to take the chance.

just looking for a 2nd opinion.

It seems stupid to relocate them that close. I thught they were in the stock location.

i agree. thus the purpose of this thread.

what would be helpful is perhaps to see some pics of what other people have done if and when the time came to relocate their AC lines.

You would probably be alright with some good heat shielding. I melted a spark plug wire track when I swapped out my plug wires. The car sat for maybe two minutes before it had melted and begun dripping down over the exhaust gaskets. Its the direct heat from the turbine housing that really burns things up. You could make a little aluminum heat shield that blocks the lines from direct heat off the turbine.

Those lines are still in the stock position. Note the stock clamp holding them in the stock position on the side of the strut tower. I hope they didnt charge extra labor for the "relocation". They didnt move jack.
