Haha "ONLY" 250kgs... Correct me if i'm wrong, but isn't that over a third of the weight as the WHOLE ENTIRE CAR!?!?! lol. You want a perfect engine for your corolla, shove a 13B turbo in it, it's been done b4 with no probs, and it'll propell your little Corolla into the 8second 1/4mile bracket un-tubbed... that's if you're prepared to spend the same amount as rotorworx did on theirs lol. By the way, Australia is producing 13Bturbo rotaries with over 900hp now, i'm sure that is enough to satisfy your chassis-twisting needs... lol
