How to make a turbo Heat shield.
By Danny/MAZMAN
----------------------------------
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.
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.
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.
