But playing by rotary rules instead of trying to put it into piston perspective, it's a 1.3 litre. 2.6 litres is just to make piston people feel better about themselves. :-)

i doubt you have a supra... especially an 879HP one

@aaroncake less gass more power?

[aaroncake]

@jeppoification We have different logic. ;-)

[jeppoification]

@aaroncake please read my statement again, logic dictates revolutions of the e shaft

[aaroncake]

@jeppoification Well, technically no. Remember that the rotors are geared 1:3 compared to the motion of the eccentric shaft. Each rotor fires three times per rotor revolution, but only once per eccentric revolution. So eccentric shaft wise, you get one power event ever half shaft revolution like a 4 cylinder (assuming a two rotor). But rotor wise, you get 3 power events ever rotor revolution. So it depends on how you look at it.

[jeppoification]

@aaroncake it fires the same amount of times per revolution as a 4 cylinder

@boardinrider I think they chose it becuase it was almost the same width as the FC. There have been FD dashes installed in the FC before, check the RX-7 Club. But it was a huge amount of work. It is far from bolt in.

@aaroncake oh god No how could he do that :( I was hoping Fd I plan on doing it if i ever find a LHD dash

[aaroncake]

@boardinrider I think 240SX.

[boardinrider]

I have a simple question... what dash is in that FC

@aaroncake i like the flutter screw the bov
