Im fully prepared to modify the tunnel in order to make the tkx fit. I was just trying to figure out what would be the best option to dump my money into first. Like you said, the wide first gear ratio tkx is 2.95 and going through all the gears should allow more consistent and ample acceleration.
Once I reach third gear in my 727 (final ratio of 1.00), it feels like it looses all of its power, I was hoping that the 5 speed would be able to restore that
