you would need a bank balence closer to the 6 figure mark to fit a rotory in to our cars
the manual swap can be done, but it is expencive, ive been lookin to do the swap 2 but i now have given up cos it will be to expencive and too much effort.
the easyest way i could think of doing it was to buy a half cut and just swapping every thing over in one go, as this is the only way your are insured u have every little bit needed for the conversion.
the other option is to sell the car and buy a manual, chicaboo did this
from what ive read i havent heard any problems
