Cost is very reasonable....and I assume if I do it it should be exterior only...Would it be better to leave them as they are, jet-hot them or wrap them? Looks do matter somewhat to me.

I have stainless longtubes and I coated them - stainless *will* still rust, just not as much/easily as mild steel - even if only for looks I think it is worthwile.

Coating seems to be the best thing to do. Any heat/exhaust energy that you can keep in the exhaust will help the turbo.(quicker spool...)

definatlly worth it, keeps away from rust, a good way to keep the heat down with out the thickness of wrap (might have clearance problems)

I coated inside and out, if it flakes on the inside (worring bout turbo damage) it will flake on the outside and you alread have a bad problem if it flakes.

Jet Hot 2000 will take the turbo heat without flaking. The stangard Jet Hot or a generic ceramic coating from a local place will crack off when the EGTs get in the 1600+ range.

On my new setup I'm getting the turbo exhaust housing done in the 2000 coating so it doesn't get surface rust like my last one did.

when I had my piping from the intercooler to the intake jet hot coated it droped my IAT 15* so i`d definatly say its worth doing the manifolds, downpipes and up pipe.

Neat reply myturbot/a, I was skeptical of the idea of coating stainless but if you saw a drop of that much that's a good thing.

I don't think stainless rusts that fast though.

Ya it gets pretty hot on the driver side of the engine it will actually melt my wire loom after a while, I have to replace the loom every 4 months or so. so i think i`m gonna do the turbo manifold as soon as i take it off again.Thanks.

So you guys seem to agree coating both the inside and outside of all the metal plumbing and the turbo housing id good idea?..is that what I am to get from this. Just like the input...thanks!

dont coat the inside of anything before the turbo.

Thats what I was thinking!

MYTURBOT/A

I`m not an expert but i don`t think you should coat the inside of the turbine housing. once you spray it won`t the tubine wheel rub because of the tight clearances between the housing and wheel? just a thought don`t know for sure.

i beg to differ, i did mine and every thing is fine. something would be terribley wrong, like egts past 1800*, which by then your engine is already gone.
alot of guys coat both sides.

RyanJ

oh well. I have no personal experience, just heard it can flake off eventually and kill the turbo...
