I agree. I have contemplated the 6 speed swap. I was told by some redneck guy that he swapped the internals out for those of a

Tercel 5 speed

? Something like that.. But I wouldn't try it. I'm not sure of the ratios, but I would look into BT/ST 5 speeds, or possibly GZE transmissions. It's not for beginners, but FWD transmissions can be converted to run in MR2...
