Turbo Heat shielding?

[tdz16]

I'm just curious, has anyone had any trouble with their turbos mounted up front and the heat coming from them? Like any adverse effects to the large concentration of heat at the turbo? Anyone use any type of custom heat shielding around it?

Also, I was wondering about the oil lines for the turbo, i did a search and didn't come up with much. Does it matter which oiling hole on the turbo is the supply and which is the drain back to the pan? And also, should the oiling holes be one on top, one on the bottom, or should they be on the sides, like so the center has to fill up a little with oil before spilling out the drain hole to the pan? Any help at all with this would be cool. Thanks.

long as anyhting that can melt is at least a few inches from it you should be fine

yes it does

And also, should the oiling holes be one on top, one on the bottom

as far as i know the oil MUST gravity drain back to the oil pan so yes it would matter... unless your using a sump to return the oil back to oil pan... but the oil still must have a clear route to escape or it will leak into intake and then you know the oil is not draining i think there is certain max angle the oil holes can be at

It really depends on what the turbo is close to. My turbo placement was described by some on this board as "Catastrophic" because of the proximity to the belt and tensioner pulley. Here it is, 6 months later, still on the stock belt with 100,000 miles on it. :D But, if you ever wanted to go with an added level of safety from heat, a shield for the turbo is never a bad idea.

Hey viper, I've been looking at a lot of your posts and what not, because I'd like to probably end up similar to you in the end. Not that that has anything to do with this post, just giving some props. So the oiling holes would be best, feed on top, drain back on bottom? How do I know which is which? I have a t3/t4 .50 comp a/r, .63 turbine a/r (not that that matters much either). If you could help that'd be awesome.

I was also looking into getting the retard controller you have for your setup. Have you used HP tuners to retard the spark at all? Or did you just go right to the msd retard control? I know that with hpt you would have to just go by rpm and thats not incredibly effective, but it would work. I'm just curious what you did with regards to timing. I'm lookin to keep this pretty cheap right now. I've got the turbo, greddy univ. bov, HPT, xs 35mm wastegate w/4psi spring, 2000 tubular manifolds, rx-7 intercooler(lil guy for now) and walbro 255lph fuel pump. I'm gonna get bigger injectors and spec 3 clutch after xmas. I think i've got a good basis so far, but not much money left. I'm getting a mig welder for xmas so then i'll fab the piping. I'm just trying to get a good idea of where everything will end up, so gimme some tips if you could, especially with regards to the oiling issue. Thanks.

What car do you have?
You will need to place it so it can drain back to the oil pan or you will have to make an oiling system with the turbos'own oil tank like my getto as h3ll oil tank I made.
The oil feed hole is going to be the one that has threds in it. The drain has a flange that can hook to it. That's the way all the turbos I have seen are set up.

I have a 94 camaro 3.4L auto, but i'm swapping in a 97 3.8L m5. So if I mount the turbo about midway in front of the engine like most the setups i've seen I should be good as far as drainage and gravity pull back to the oil pan. This should also help it as far as flow from the sending unit split. Sound good?

there really arent many other places you could put the turbo. I would recomend you look into forward swept headers if you want the best performance.

[tdz16]

Oh, well, there wasn't any question as to where the turbo was going generally. I always planned on up front. I just meant as far as height. I figured about mid-height is good for oil flow. Forward swept headers would be ideal but FFF's way looks a little easier to fabricate than headers. I dunno. I'm still deciding what to do with respect to that. I'm thinking the FFF way first, then in the future upgrading to the headers. Thanks for the input though, i really appreciate it.

I don't like puting them up high in frount.
I'm don't want to sacrifice handling for ease of construction by putting weight up high and forward. I was going for headers that look kind of like block hugers that go down some.
That is why I can not make them over here.
I got this hot tub water filter to jet line that is about the size of one of my primarys. It is cool stuff you bend it and it takes the shape, all most like a pipe form of modeling clay.
I can mount the oil tank realy low so the turbos can go lower than a normal engine that has a gravity feed to the sump.
You can heat sheald the turbo with header wrap but wraping the headers them selves will make them crack sooner. Unless you make them out of an alternative materal.

man its been like 6months since i seen my turbo but i think it has a in and a out labe for the oil

my project is on hold till i finally get in the states and can work on it some more

No ****! I know all about that.

sucks don't it :(

Have the exhaust manifolds and turbine housing ported/polished and get them jet-hot coated. the coating will keep heat in more, and the turbo gets 80% of the energy used to spool up from heat. plus, it won't clutter up anything in the engine bay.

i'll be using a heatshield, they are worth it.
