Good stuff dude, love to see it!

Maybe I missed it, but what TB are you going to use for your DBW setup? Generic Bosch unit? What size?

Car continues to look best in class

Ended up with a deal through a friend on his lightly used G19 Engineering square top intake manifold with NC TB.

Thanks! The NC is looking fun as well!

Still progressing through the design of a new v2 bumper/airdam to keep the side pod coolers from dumping air into the wheel wells, as well as a v2 of the wing to have a spare, but also a few improvements. Lastly made some progress on the DBW mounting bracket for the NC Miata pedal. Should be completely swapped over to the LinkG5 ECU and DBW setup sometime this spring.



That fender oil cooler arrangement has been done before. Lokiel has a very neat solution, quick search didn't find it here, try his thread on the local MX5cartalk forum.

Appreciate it! Did some digging, but I didn't quite see the same setup. To clarify, I've been running the side coolers for a few years now, the change is the exit ducting from the coolers. Currently theirs seem to dump straight to the wheel wells as mine do, but the thoughts for the bumper revision are exit ducts before the wheel well on the sides of the vehicle/bumper rather than inside of the wheel well.

That is exactly how Lokiel did it, intake through the hole, outlet a slot at the front edge of the front guard. He's on here, you could try PMing him here, or through this build thread. I looked there but the site has had problems and the references/illustrations seem to be missing. From memory he used 3D printing for the front and rear halves of the cooler enclosure, that file would be a useful starting point ...

Ah okay, thanks! Yeah I'll skim through again, I must have missed that upgrade to their setup when I went through it the first time then
