I bought a standoff to mount the rear side of the shield. I may shorten it a touch as it crowds the heater hose a little bit.










Starting the turbine/downpipe shield...I wish I had sheetmetal tools to make this. It will basically be a cut and splice process. I used an old mandrel bend and cut it in a quarter to use as the front corner of the shield. Will probably mount it to the turbo using the 2 bolts around the oil feed.












Going to try and keep the gap around .5" around the turbine housing. And fasten this fabric to the underside of the shield.

 

Very nice man!

Have you looked into ATP covers out of California? I think that's their mane. The owner is Miguel. They are inconel covers they custom make for turbines and things. Very nice stuff and what I use on my turbo.

 

Thanks! I did send information to "turbosource" a while back about some shielding and never heard back from them. I didn't check with ATP though.

At this point I think what I'm doing will work well enough for me. And being a little cheaper than inconel is nice. I figure inconel shielding on a manifold, downpipe and turbine housing would run me $1200-$1500.

Also I have gone too far into this shielding.







Making a front plate to fit to the radius of the shield. I needed more of the radiused section so I'm just bending the front plate to continue the radius.





















Here is the mounting plate that is going to connect to the turbo.











Setting up the 2 pieces and tacking them togeher. Then extending the mount to cover more of the shield to make it a little more sturdy.













Cut a 2.5" strip out and manually bent it around the turbine. I don't have a slip roll so it isn't perfect.














Texture mod applied to most of the shield, then welded the seams. I had trouble seeing the puddle and the seam some of the time. My hood was either too bright or too dark in between a 9-10 shade.
















Now I have to make standoffs on the downpipe and run the shield down to that point. Easiest way to make the rest of the shield is to buy a 4-5" mandrel bend. But I don't want to spend the $70-100 that is probably costs, so I'll just keep using the .050" sheet metal I got.

 

Holy crap, That turbine shield is mint. Did you use an English wheel to get the curve?

 

I wish I had the tools. I used a piece of wood and pushed the stainless against it with my hands.

Its only about .050" thick, so it is fairly easy to shape.

 

So impressive man! That cover is sick.

BTW, dropped my S off with Carey Bales yesterday to get everything finished, should be completed by spring. I'm super stoked he is helping me out with getting it done. He is a super good dude.

 

Nice. I'm looking forward to seeing how it does with strong parts. I feel like he has built half of the fast s2000s lol.

 

Almost got the shields done except for the insulation on the inside. I went ahead and split the shields so one is on the turbine housing and one on the downpipe section. This will make install the shields a little easier/possible.


The current turbine shield is shortened and another radius from a tube was added to the outlet side. Then the inner flat was mocked up and transfer to metal. There is about a .125"-.2" gap from the inner flat to the turbine outlet (beside the cutout on the bottom.









Standoffs for the downpipe shield. I may add a third that will be on the valve cover side of the downpipe.












The middle strap of the downpipe shield. The sides will made from a split 3" 90° elbow. The radius matches real close to the strap.









Tacked together. The section bent perpendicular will slide under the downpipe. Most of the shield will cover the vband clamp.










Gapping the downpipe shield Also shows the radius piece I had to add at the bottom. Also test fit it in the car. Luckily it clears everything it needs to. I may not even need to make a shield for the heater hoses.














Spacing on the inside of the shield. The insulation should take up about .30" of space.







Cleaned up the outside for the final look/welding









And welded. Also added a small piece on the outboard side (still have to gap it to the dumptubes). I will probably leave this as is and not cover the dumptubes. I don't think I'll have much in that area that will be really sensitive to heat.

 

A true work of art.

Here we go again, more heat shield stuff. I hope it pans out and works decently and doesn't crack etc. I'm getting tired of messing with these lol.


Finally finished the front mount of the shield. Installed nutplates to bolt to the bracket I made. Space was tight on the inside....I should have located them further apart, but it will work.











Making inner shield out of stainless "foil". It is about .005" thick. I folded the edges to give it a little strength and help it not be as sharp. Then backing straps were made and it was riveted together. The riveting came out rough lol.















Also weighed the turbo/wastegate/downpipe/shield assembly (40.2 pounds). I guess that seems about right. The manifold is around 18lbs.....so a total of about 60 lbs hanging off the head. Mocked up the turbo to see how the intake will be. I'm going to try and make a filter box with ducting to the front bumper. It makes more sense putting the filter in front of the strut tower. Probably way easier to make it fit in the center of the bay though.









Or maybe I cut a hole in the hood.








Here is the insulation and inner shield. Mimicking the outer shield made the most sense, but is a pain. The insulation is like a ceramic blanket. It forms decently, but will break apart when overworked. I wore a respirator, but should have wore throwaway coveralls too....stuff is itchy.











The shields are going to be held together with copper rivets. I made spacers to offset the inner shield from the outer. The rivets are a touch short, but I don't see anything that will stress it to break the shields apart. If I have issues I can swap rivets later. It was temporarily put together to check for fitment/installation issues. I will have to trim the inner shield in a couple spots, but its working out so far.

















One of the reasons I used rivets and not bolts/screws. The clearance to the dumptubes is a bit tight and the rivets are probably the smallest option.

Also shown is the installed clearance between the shields. It should work nicely keeping the insulation in place.










Turbine housing insulation will be last part of the shields hopefully.
