Huh? Me?




My oil feed comes off of a T block on the oil pressure sensor.

Re: Say good bye to rusty turbo housing
 

i dunno about the bbq paint, but the VHT manifold paint works really well. i did my wastegate housing and valve in that, and my manifold, and no signs of any issues after a good thrash with the valve in the wastegate the wrong way around. (to ensure there was no boost) a mate of mine has done his turbine in it, and i intend to do mine too. its good stuff.

Ceramic coat is the best. especially polished like a mirror, but for a cheaper coating to prevent rust, i like to use DEI paint. it makes your turbo a nice gloss black that doesn't scale off with heat. Looks very much like your holset turbine.
it's supposedly illegal here in Canada but who cares, I have some. ;D

Re: Say good bye to rusty turbo housing
 

Yeah I used that in "aluminum silver" on my down pipe... I ended up wrapping the down pipe! It keeps it from rusting until it gets scratched but it isn't nearly as durable and ultimately fails.

Re: Say good bye to rusty turbo housing
 

yah i've tried a variety of things now. vht flameproof, bbq stove, and por-20 2000*. Daily driving kills all of them eventually. they just aren't durable over long term. :-( and yes i am very thorough when it came to prep work.

someone please find the ULTIMATE high temp coating pleaseeeee hahaha

except where is hmt ?

Re: Say good bye to rusty turbo housing
 

i tried both the VHT and the DEI and I found the VHT is more powdery and remained porous so you are sure it will get dirty by the time you're done installing the manifold! The DEI covers very well in a single coat and looks smoother and shinier. normal since it's designed to "freeze coat" the DEI thermal wrap.
on the manifolds and turbines i treated with it, it did not fade away with heat like barbecue paint does.

Re: Say good bye to rusty turbo housing
 

Been driving it for a while now, running awesome. Exhaust out the back, intake is about 2 feet in front of the tail pipe. Haven't noticed any issues, runs smooth at all RPM's. I'd prefer to feed it cooler air that didn't pass by the engine first and off the hot ground but haven't figured out how to run it somewhere else without looking like garbage. I could go up into the trunk but that's not exactly cool air in there either.

Oil is from a sandwich plate up front, The short braided line you see attaches to some tranny cooler line coming from the front of the car. The thing at the end of the braided line is a check valve to prevent oil from draining into the turbo from the line while parked. The check valve requires .5 PSI to allow flow. It's not to prevent backflow. I used the stainless line at the turbo to protect it from any heat. Check out my "94 Q45 rear mount turbo" write up for detailed photos.
