So I saw a friend of mine posted his old Miata racecar for cheap and it was pretty much exactly what I was looking for. So I went there and got it for even a bit less (cause I wasn't going to scrap it and it was going to a "good home"). Picked it up with my grandpa's sweet old 530 turbo diesel: Small caveat:
It's missing: the engine, gearbox, diff, driveshaft, fuel pump and the cluster. Oh, and the brakes are shot. Great stuff for a project car! I still have a 1.8 NBFL "big brake" kit which needs a rebuild, the drivetrain will come from RusEFI car #19 and the fuel pump will need an upgrade anyways.
The plan (theflyingdutchp has already had a big spoiler ):
- Twin GT1752 spooled sequentially (parallel, not compounded)
- up the compression, aiming for 10.5-11
- run as much passive cooling after the turbo's as possible to keep IATs low (and high IAT during cruise)
- use water - ethanol during boost
- experiment with cooled EGR (optional)
- a big want: mount an LPG setup (because cheap fuel and high octane)
Goals:
- Flat torque curve from 2500 to 6000RPM
- Cruise fuel economy: at least 14km/l (33MPG)
- Good drivability --> decent NVH, workable in slow traffic (which my turbo Smurf isn't....)
- Have two turbo's on a 1.6 Miata!
