in some european countries(not sure which off hand) but you can't excede certian hp figures. not sure if it's a flat # for all cars, or if it's a % of the cars stock hp, or what, but it is true. after certian mods you have to have dot approval that your car isn't but so fast. we joked that if the dot would dyno your car for inspection then that'd be a cheap way to dyno tune, but i doubt they do. perhaps the mr2/uk guy could explain since he says that's his reason.
and if you(mr2____) could "easily afford" to do a motor swap, why not do some head work, cams, lighter internals, etc? oh yeah, the mr2 is perfect off the showroom floor :rollseyes:
