Nice craftsmanship. Looks like a great drag race setup. Any timeslips?

Maybe this is the solution bbundy has been looking for. Haha.

patsmx5, next project to go with your compound turbo?

First tim I've seen someone use a proper auto Trans behind a miata engine. Would probably be really fun to drive with the manual shift mods. My dad's corvette has a manual shift turbo 400 Trans and it's a blast to drive.

We are lucky here in Australia the same auto was in a turbo 6cyl that people build so the parts are available only 2 issues we hit machining the rear extension housing to fit the bigger shaft and having a stall made apparently mazda's design is odd not enough room to fit parts needed but they sussed it out and frankestiened one from another converter

In the 6cyl turbo they claim 350rwkw all day so i think a 4cyl will be a little more so iam keen to turn it up next concern is diff and axels

This is interesting! Liking the coil setup and good craftsmanship it will be a blast to drive! 300wkw is around 400whp right? That sounds crazy fast. Subd
