I'm thinkin about importing a 3000Gt from Japan. importing laws in Canada restrict me from getting anything newer than 15 years, so I'll be getting a 1991. now I know it has a 2 bolt crank and I do know that the 4 is better, but I only plan on doing mostly just some simple bolt on mods(underdrive pulleys,clutch,etc.) and some tuning. What I basically want to know is will the motor be able to handle this? I mostly wanna know what can I do without having to do the 4 bolt swap or tearing aprt my internals.
