I also noticed that your wheel wells are not the stock M Roadster ones, the ones with the brake ducts, as well as the intake tube on the driver's side (not needed in this application, obviously), but is there any particular reason you switched to different wheel wells? Just wondering.
See, I'm just looking for all the help and wisdom I can get with this turbo project. I used to be a Mazda guy with a couple of Miatas that I turbo'd myself, ground up, but those seem like a cakewalk compared to turboing an S52. Those engines (early Miata 1.6s) were made to be turbo, as they were in the 323 gtx. Piston oil squirters, sealed off oil feed and return points for the turbo, the lot. I ran TD04Hs on those, but I'm going with a T3/T4 on this car.
I'm not looking for the 500+ whp you pulled off, just a nice round 350, see how that feels and then maybe step up to 400.
Thanks ahead of time for the help!
