possible swap solution, alot of work but it can be done- gt4 gearbox can hold 600hp stock http://www.clubprotege.com/forum/showthread.php?t=43964

cool, just be a matter of getting the parts then

Think it would bolt into our cars?? Would need to find some sort of bellhousing adaptor I guess. I also wonder if the toyota unit is stronger than the nissan. I see how it is stronger than the Mazda.

haha I just have a spare gearbox cheaper and drops right in!

it takes about 4-5 grand to make the gtir box stronger, gears,lsd-. after that you still have to deal with the case. if you can fabricate a bell housing adapter, or other mods it can work. as far as drag racing the gtir box is weak, the hardest part of this swap is sourcing the parts
