Homemade Heatshield
Hey guys, I'm new here and I'm in the process of piecing together a used Greddy kit. Just for some background, I formerly owned a 323GTX and a 92 SE-R with a GTi-R engine swap with about 250whp, and I've had my Miata for about 2 years, but I really miss the power of my SE-R.
Anyway, I had some free time so I fabbed up a DIY heatshield for my Greddy kit using a SS 1qt pot as a starting point. I only have the one pic from my cell phone camera, but I thought I would share and see what y'all thought. I still plan on getting some wrap to protect my master cylinder and various hoses, but I think this should help. Not bad for a $7 SS pot from Walmart...

Clay, that looks totally legit man, nice job. I totally love **** like that!!!
You're gonna want to expand on that though to protect the most vulnerable part under the hood... the brake reservoir. To have a really effective heat shield, you've gotta protect the brake reservoir and your heater-core lines from both the turbine housing and the DP. The Greddy top-mount design makes perfect sense to leave room for PS/AC and makes it easier for the stock crossover pipe to mate up, but placing it that high cooks the hood and a few other things.
You're also now focusing the majority of the heat off the turbine forward right onto the oil-feed line.
I've got a Begi manifold, but check out my heat shield and see if you're interested in fabbing up something like it. I tried to make it so all of the heat was focused down. No matter what we do, the hood is still gonna get hot-as-****, but when I run my hand over the hood, starting at the windshield and sliding my hand towards the headlight, it's super easy to tell exactly where the heat-shield ends as it goes from mildly warm to !!!HOT!!! directly above the compressor housing. I used existing holes in the inner fender lip to mount the bottom half, and the top half uses the valve-cover bolts.

Thanks for the tips guys. This is just a 1st draft sort of thing, but I wanted to get some input. I'm definitely planning on more protection than just this shield, but I had the parts and all it took was a little time with some tin snips and jigsaw playing around. I've got access to lots of scrap sheet metal, so I may try something more along the lines of samnavy.
BTW newbsauce, not sure if you knew, but this is your old Greddy kit. I bought it off of the guy you sold it to a few weeks ago.
