20B Single Turbo 3rd Gen RX-7

i noe this engine puts out alot of power but what did u do about the tranmission did u leave the stock 5 speed tranny

The car was built by RotorSports Racing and they used the stock FD transmission.

wat does 20b stand for

The 20B is Mazda's 3 rotor engine, based on 13B geometry. The "20" means two litre, the B is to indicate it is the 2nd generation 3 rotor. Actually that's a bit inaccurate since there was no 20A and the 20B is based a bit on the 13G. But at the time Mazda was playing a bit with designations. The full name of the 20B is "20B-REW". "REW" stands for "double turbocharger" in Japanese.

Well since each rotor has a displacement of 0.654 liter, you have:

2 rotor x 0.654 = 1.3 so you get a 13B
3 rotor x 0.654 = 1.96 ( rounded off to 2.0) so you get a 20B
4 rotor, 2.6 = 26B you get the idea.

stock fd3s gearbox can handle up 2 600hp, just need a good heavy duty clutch

depends on how its modified and tuned. even std they drink more than your average V8.

Holy crap! My bridgeport gets better mileage then that. What A/F ratios are you running?

On a good run it's not so bad, it's just the first 10 minutes seem to drink fuel as it's warming up.

Have you ever run your bridgeport on 4 10 minute journeys a day? If it gets better than me, then I'm going to cry.

I think you might have to cry. :-) I use my car to make service calls all the time and often make a lot of short trips in one day. I'm at about 200 miles per tank in the city.
