Isn't the RX3 a 12A motor?

the motor was a transplant i take it. kind of a bit of a hack job in my opinion. but the guys very enthusiastic about it. car is tubbed, turbo II trans, ford 9" rear, skinnies, full cage etc...i cant imagine the car wieghs more than 2000lbs. the engine has been bridged/ported?!?, he just put new rotors in it and wants to build up a turbo system...so i figured i'd ask. theres a ton of great info on that Rx web forum which he is researching. thanks again gang!

ps has anyone ever seen the method in which these rotorary draggers launch? its crazy...they dump the clutch w/ the motor spinning 8k+

I learned how to drive on a '75 RX3 Wagon. Huge 4 bbl carb that was a large as the engine. What a great site to outrun my frinds in their late '70's "musclecars" with my paintmixer!! (I think I got worse gas mileage though.)

Did he put in Low compression rotors? I assume it is a 13B 4 port out of an 84-85 GSLSE? Or is it a 4 Port 13B Turbo II Motor?

GSL-SE is a 6 port motor. The 4 port motors are either from earlier rotary vehicles like the RX-3 and REPU, or turbo FC's (second gen) and FD's (third gen).
