I had a 1980 Mazda GLC grocery getter that I did an engine swap on.
I swapped in an RX7 rotary and tranny.
The thing went like a raped ape!!!!
Scary on the highway when you opened it up.
She started to get light as you passed 200 kph.
Wish I had known about ground effects back then as it was still pulling hard at that speed and I still had a gear to go!!!!
Drag racing it was dang fast too. Once raced some guy that had a sparkling new Indy Pace Car Camaro.
Beat him by 1/2 dozen car lengths in an 1/8 mile.
The dude was really pissed!!
