can someone fit a 3-rotor into my 280Z?  That would be fun!

I think it would be cake to put a 3-4-6 rotor into most anything.

My question is: are these 3 and 4 rotor builds always custom or are there kits available?  For as much work as the guy in that first link I posted has gone to, I can't imagine many would follow in his footsteps.  That leads me to think there are kits, or some easier way to produce these fire breathing monsters.


mazda used to offer the cosmo with a 3-rotor configuration (20B) in the early 90s, but i think most of those have dried up.

there are stateside companies filling the gap with the 3+ rotor crankshafts and housing kits.

didnt you get rotors in the states ???

youtube pac performance , been around for 20+ years , 7 sec quarters in rx3's are scary shit

suzuki made a rotary bike back in the day

i dont care if you have been a mechanic for 10 years doing something for a long time does not make you good at it, take my gf for an example shes been walking for 28 years and still manages to fall over all the time.

Suzuki had the RE5, and there was another rotory powered bike too, maybe a Guzzi?

I gotta come back to this thread when I can get somewhere where I can watch video. Probably at my home computer where I have the Bose linked via bluetooth.

I'm sure it could be done. There's a video on YouTube of a 4 rotor rx7 build that would give you an idea as to how long the housings are. I doubt it's much longer than the I6 block in a datsun. 4 rotor builds though are crazy expensive.

I, on the other hand have been craving a datsun 280 to put an rb26dett (r34 skyline engine) into.
