How TO: Build Turbo Heatshield
Ok, here is a very good do it yourself heat shield that anyone could do, and the end result is fantastic, just as good as the real deal if not better,
as there is no welding on it, and wont cost you an arm and a leg. Go to the usuall shops like k/mart, big-w, target ect... where you will need to find a large bowl, made of stainless steal. I used a stainless steal bowl of 0.3mm, already polished. its thick enough to not flex/vibrate/bend, but thin enough to cut easy. Look for the design you would like and the shape of it, its up to you to find a look that you will like, i bought a plain and simple design, with straight walls, no bends or funny shape design. You can get aluminium ones, coppers ect... but i think stainless does a better job and ends up looking the best. You will also need to measure your rear exhaust housing diameter, so as to not get a too small one or too large. My turbo is 210mm o/d and the bowl i bought is 220mm, so i have a gap of 10mm between my housing and my shield. http://i34.photobucket.com/albums/d1...an808/Pan2.jpg http://i34.photobucket.com/albums/d1...an808/Pan1.jpg Once you have decided on your bowl, you will need to make a template. I just used a thick cardboard to make my shape. Bend it to the shape you want, and sticky tape the other side on, so as to have the nice bendy/oval shape(see picture). Put it on your housing and try to get the best possible bend and the look that you want. Remember to get the width that you desire as well, and the lenght. On my turbo (gt42) i had small threaded holes on the rear part of the housing, so i shaped the cardboard and made the holes that you see behind it. This is where i will be bolting up the shield to the housing. I understand that every turbo is different, but if you have these holes at the rear of the housing, you can measure them yourself and drill the holes to match your housing. http://i34.photobucket.com/albums/d1.../Template2.jpg http://i34.photobucket.com/albums/d1.../Template3.jpg Now that you have a template to make your shield from, its time to cut the bowl to suit. So measure up your template, put it against the bowl and make the required markings where you will cut it off. You will be cutting of the head of the bowl(the top part where the handle is), and leaving the bottom part of it so you have something to bolt up to. I used a cutting wheel on a grinder, taped up the bowl section with masking tape on the part i will use, so not to scratch/damage it, and cut my shape. http://i34.photobucket.com/albums/d1...808/Cutpan.jpg Once cut,i used a fine file to get rid of the sharp ends, and then used a fine sanding wheel to get a smooth finish. I cut the lip at the front of it just a bit, to make it look more professional. Now all that you are left with is to put to template against the shield and mark the holes where you will drill, remember, put the template on the inner side of the shield when marking(not on the outer side), this will make sure you dont stuff up your measurements. Once you have drilled the holes, again, sand down the sharp edges that the drill leaves (tip: drill from the outside of the shield as this leaves edges on the inner shield where you dont see it). http://i34.photobucket.com/albums/d1...8/Template.jpg http://i34.photobucket.com/albums/d1...808/Pancut.jpg Now to find the correct bolt size and thread that will match your housing thread and bolt it on, and your done!!! Then enjoy the mighty fine look it will give you as well as helping all that heat under your bonnet. On the australian/RHD, our brake master and clutch master is very close, it helps greatly with this shield. I couldnt be more happier with the end result. I paid AU$26 for the bowl, and did the labour myself, so that cost me nothing, In the shops, they are asking AU$250 for this piece. I have higher resolution pictures, but due to size, i needed to be fair to everyone and made them smaller. http://i34.photobucket.com/albums/d1...anonturbo2.jpg http://i34.photobucket.com/albums/d1...anonturbo3.jpg http://i34.photobucket.com/albums/d1...Panonturbo.jpg Credit to Bosshog, not me. |
This is a cool idea.
|
wow, great idea, add'd that to the walmart list
|
thats awsome.
|
wow!!! make me one!! lol, i got a GT42 also.
|
hrm.....
|
looks great.....but I'm still laughing a bit knowing what it actually is :) Still great idea though.
|
haha, awesome.
|
I'd have left the handle on for lulz. Gread idea btw.
|
This is awesome.
|
Great idea, you could sell a $10 pot for $500 with very little effort. Just use use both halves.
|
^ sad but true... looks good.
|
this is epic, must do when i do single
|
wow, looks great.
|
tricky tricky
|
just wait until your wife finds out what happed to her missing pasta pot...
|
man that looks realy good lol
|
nice! got an otyer walmart goodies to show us? :)
|
now thats ingenius and penny wise at the same time ...
|
awsome job.
that's a great idea |
We used you're technique to make a heat shield for my brother's 60-trim srt-4. Turned out great!
|
Eric, nice choice of SS pots.
Have you considered reversing it and shielding the 360º of compressor housing from the radiant heat of the turbine housing? Barry |
That's awesome! I'm gonna do this. I have already been constructing a makeshift airbox from a coffee can and some heat shielding to go around my filter, and hoses coming from the headlights (once I do a headlight conversion). This is so cool though!!!
|
This is some creative thinking:P
|
very good idea cant even tell its a pot

Thanks to this thread I made a turbo heat shield from a 6 quart stainless steel pot from target. It's a little big but it worked good, see pics, it was the best thing I could find, I also checked Walmart, lowes and kmart, and looked everywhere including dog bowls lol. With this 1.32 a/r turbine housing there is even less space between it and my lower intake manifold so I could not fit my turbo heat blanket. I also had to rotate the heater hose pipe so it sits down below the turbo now, this was easy I didn't even have to remove the hoses, just the hose clamps, and I made a long bracket to secure it. I have good heat reflective tape on the lim and I might also try to make a heat shield for that and I need to put my exhaust wrap on the new 4" downpipe.
|
Haha I forgot all about this. I never did try this because I couldn't find a pot the right size.
1.32 turbine? That's pretty large. |
Yep, it feels the same on the street as my .96 undivided. Ya you might have to use something different than a pot to make a smaller one.

And here is the heat shield I just made for the lim. It's a thin piece I was using to make a template, then I just decided to use it instead of making a thicker one which would be alot harder, I could do that later, this one works to block some heat as I confirmed with my little torch :nod:.
And earlier I tested out the stainless steel pot turbo heat shield and it works great :icon_tup:. And here is some more pics. Exhaust wrap going on the 4" custom downpipe next. On a side note, my new setup (with the divided 1.32 a/r turbine housing, the turbo heat shield and 4" downpipe and midpipe to my greddy 3" catback) has better boost response and hits 10 psi of boost significantly quicker (about 300-400 rpms) than it did when I had a open undivided .96 a/r turbine housing with a heat blanket and 3" exhaust. Once I get a 4" catback made for it or just remove the 3" catback, it should be even better. |
3 years later and I'm barely seeing this. Great ingenuity Viking.
So how is the heat shield holding up now? Give us an update. |
^If you're asking Viking, I'm pretty sure he sold that FD and bought the NSX in his avatar.

Excellent idea, that's called using your head 8)
