Turbo Heatshield

popup · Post by **popup** » Sun Jul 08, 2012 6:13 am

So, I don't have a heatshield for unknown reasons and I'm going to fabricate one up out of some 1mm stainless sheet. What do they usually mount onto? I've seen from other photos there is a close one that covers the exhaust housing of the turbo and a "wall like" one that zig zags around the side.

If you have a factory manifold it will be easy to mount the shield using the horizontal holes in it. The shield bends 90 degrees up and over the exhaust section. It's probably more beneficial making the shield for the clutch & brakes - unless it's a left hand drive. They mount using a bracket on the firewall near the clutch master and another one near the strut tower. It's a complex shape, probably best to purchase one of those babies.

I have a feeling it was removed due to a custom downpipe so I'll get some photos. In the service history it was noted to investigate temperatures and it said it was OK, but I'm not so sure. Just had the wettest June on record so not great for working on cars.

Well, turns out the turbo is a Garret T3 off a Cosworth and the downpipe and (I think) the manifold are not standard! Need to upload photos. I see the bracket still there on firewall and maybe yes theres one around the strut tower.

Starting to wonder if heat wrap the downpipe and one of those heat covers for the exhaust housing will be easier and better for servicing? Downpipe is stainless steel so no worries with rotting it out. Opinions?

Heat wrap is good with one proviso...don't get oil on it or you'll have an external combustion engine!

Much the same over here ATM :(
i would still recommend the hydraulic resivour(spelling??) stock shields remain in place whatever you do.

Ceramic coating. Spend the money on it. You'll love it.
My mate had his extractors ceramic coated one of the best things he did under the bonnet to control the effects of the heat.

Sounds expensive, just a quick google on ceramic coatings is about 300-400 AUD!

Think I'll fabricate a metal one. I'm guessing the stock one was removed because of the Turbo conversion and it didn't fit back again. I'd say the downpipe is about 3cm away from the big part of the master cylinder!

Thanks for all suggestions, glad I didn't heat wrap as there is a leaky problem with the turbo oil return pipe!

Anyone got any good photos of this area so I can see what stock heat shields look like?

you can see in the photo the bracket where the heat shield connects to at one point next to the master cylinder there on the firewall.

Thanks! Its not looking easy. I see the other bracket now, needs to go up and over the hard brake lines.

Decided to build a heat shield, I don't think the stock one would ever have fitted back without cutting big holes in it. Will update my build thread tomo.
