Gear ratios are best for efficiency in the HX tranny, worst in the EX tranny. Finding an HX tranny might be a good idea. Regardless which tranny, be aware that the Input Shaft Bearing is a common point of failure and you may want to replace it while you have it apart.
Yes, but is it possible to use the EX engine as an HX engine with the HX ECU? I think the pistons and cams are different, but otherwise the motor is the same.
