n/a rx7 track car

[Maxt]

Finally getting about an hour every odd day or so to pick away my track car(for which track I don't know now).

Car: 1988 Turbo II Fc3s
Engine : 20b peripheral port
Weight target 2000-2200 lbs.
First project is putting the driveline together, then spot stitch weld all the body seams, Cage, bodywork/kit install, then fit the seats and wire it.
This thing will be louder than all hell, but it's going to remain street legal in terms of lighting and what not, and will be occasionally street driven.

Car is just a rolling stock TII shell right now, it's going to the body man in a month or so. The kit is the full genuine Tamon widebody kit, to kill the weight , I have carbon doors and lexan hatch for it. The rear hatch has to be over a 100 lbs just by itself..
The kit:

Centering mandrel machined

[Maxt]

Trans adapter layed out

This is where I wish I had a CNC mill instead of manual hand cranker.

The leftovers from 3 hours of manual machining.

[Maxt]

The semi finished result, FC bellhousing mounted to Viper six speed sequential dogbox.
I have to trim the corners down yet and give it all a clean up, but hard part is done.

Next is the engine, as it sits now, I have to get back on the mill and make the manifolds/piping for the individual throttle bodies, and then fit it to the car.

I can already tell this is going to be my favorite build on beyond.

3 rotor peripheral port? Sickkkkk

[texasnick]

Wow cool build.....never really knew the potential of N/A rotaries until I saw that yellow FD on best motoring.

Good luck! It's going to be a beast.

This build is going to be awesome, keep us updated regularly!

Hmm, well ultimate goal would be 400 at the wheel, but anything over 375 will suffice. The power is in the exhaust and intake tuning. It takes a fair bit of trial and error and dyno time to find the right resonant lengths in addition to the diameters. The 2 rotor version of this engine made 238 rwhp with no real time spent tuning the intake or the exhaust, plus it was built out of sweepings off the shop floor, so I think a fresh 3 rotor with some dyno R&D should be able to make a fair bit more.
It's easy to make pretty big power from a turbo rotary, but the linearity of the n/a motor is far better on the track, and on top of that , less thermally loaded than a turbo motor. I think my n/a 13b car was actually faster around race city than my turbo car, even though on the straights, the turbo car was astoundingly fast.

Yes it is, waiting for the clutch to arrive now, along with a bunch of other stuff..
