You'll be grenading 44s left and right with that kind of torque.

all but the tach
and there is some info on the web about it.

I have a 4 cyl harness and computer so... the stock flywheel has 4 notches 20 degrees apart then 180 degrees another set of 4 notches...
since the 4cyl tops out at 5 and redlines at 6... the 4BT as of now its max is 2500 or HALF of 5000....
so if I trick the computer into thinking that the motor is turning twice as fast as it is then at 2500 rpm of the motor the dash will show 5000 or the full range of my gauge.

but there is no room on the flywheel... so will use the bottom pully of the 4BT to make my notches

Love the choice in color! I would have really rethought the whole 6 speed tranny though. I have one and I can tell you right now that they suck. There are lots of problems out there about them popping out of gear and such.
