How important is it to use heat shields on the stock series 5 turbo? I will be using this turbo in an 85 gslse but don't have the heat shields. I have a series 4 turbo as well that does have the heat shields but would like to use the series 5 since it's better.

Does anyone have any series 5 turbo heatshields they would donate to my project? Or sell for a small fee? I'll pay shipping of course Thanks

 

I dont have my heatshields on my s5 turbo in my s4 car anymore. Haven't noticed any problems. Its been that way for over a year.

 

Very important. Not using the heat shields will cook all the rubber in that area (eventually).

 

Agreed, and the wiring could also be cooked aswell.

They came from the factory with a heat shield for a reason.

 

Yup that's why I want them, I was told that the series 5 turbo on a first gen sits pretty close to the idler arm bushings.

 

That should be the only reason you need to keep it

Not only does it prevent the rubber/wiring from hardening/cracking, it keeps the intake charge running through the intake manifold from absorbing the exhaust manifolds heat.
Its far from a weight saver, not to sure why you would want to remove it there wanked. Or maybe your like me and your too lazy to put it back on

 

I'm not going to say the heat shield is a bad thing but I don't have mine because a)I'm to lazy to put it on and b) because I've taken my turbo off about 4 or 5 times already and am about to do it again so I don't want any more work than it already is to take the turbo out. If I where smart I'd keep it in but oh yeah there is a c) mine broke the first time I took it out. Keep it, it's the smart thing to do.

 

well the consensus seems to be keep the shields, or in my case find some and use them! Do you guys know if they are still available at the dealer new?

 

Keep them!

That turbo glows....best to keep that heat out of the intake manifold if you can help it.

 

If your shield is broken/missing or whatever, and if you can find it at the dealer, I wouldn't be surprized if the damn thing is 100$ or so... Point being, buy yourself some thermal wrap and do a better job than the standard heat shield.

 

New shields....expect 50 bucks each.....

There are three.

Ouch...

Be cheaper to buy one of those turbo blankets...

 

You can always make your own. Go down to your local metal store, get some sheets of stainless and a pair of sheers. Not hard.

 

yeah, I think I'll wrap it or use a turbo blanket. Thanks all!

 

Post a WTB over in the parts section. I found mine for 45 shipped. Well worth it IMHO. And yea I have about 1/4" between the shield and the idler arm.

 

damn, that's close! series 4 turbo wouldn't sit as close would it? I have both but was going to use the series 5

 

THe turbo blankit is so much more superior if you have a spare 100$ or so. It will cover the entire surface area of the turbine housing, and keep the heat, going straight out the downpipe. With the shield it will protect the intake from immediate heat from the manifold/turbo, but the air in the engine bay will heat up quick and heat the air going into the filter, and heat up the intake manifold eventually (not nearly as bad as without the HS).

 

sounds great, can you recommend a brand?

 

Can you tell me what gauge of stainless steel would be minimum to use.
Thanx,
