I was searching on RPW's website and came across the throttle body section for our 64 motors.
Rpw sells not only a 59mm unit but also a 63mm unit...
Has anyone ever purchased one of these?

I know it would prob. be more cost efficient to buy the 1g tb and just swap but I was just curious.


Also, I've heard that in some nissans/mitsus..removing the balance shaft yields 15-25 hp depending on the car. Has anyone ever done this to the galant and if so what would be the downside(s) of doing this modification?
