TRX: from Tyrannosaurus RX, the small block Ford powered '79 RX I was driving when I joined the forum.
One track day I drew an instructor who raced a rotary RX in some SCCA class. I think he acquired V8 envy about the third lap...
There's even a Hitler video about V8 RXs:
https://youtu.be/zxsY4lEGRBIAH: "All our RX-7s will meet just outside the city where we will take on all comers... I have no fears. Steiner has installed a new LS2 in my car."
Jodl?: "Mein Fuhrer... Steiner... Steiner was instructed by us to put in another rebuilt rotary. We couldn't de-soul another fine car."
AH: "...what the hell were you thinking? ...not another rotary. I was going to show my taillights to that idiot with the big block Camaro SS... This will be the third rotary in two years. I barely paid off the last one! ...I wanted some torque!"
