and you get the joys of no rwd transmissions bolting up to them
so, custom starter / modified bellhousing situation
for a motor that does , to the wheels, what a KA with intake and exhaust will do.
What a good choice! Lets throw the torque out the windows!
Be realistic, guys.
in order to make a motor that revs to 8000-8500 but with ap owerbgand only from 5500-8500 effective in a car like the 240sx you'd need to get closer ratio transmission and a much higher final drive, something like a 4.5 - 4.7 to make it nice and peppy. that's how the hondas work so well, is with gearing..
a taller first gear with much closer all of the other gears, and a good final..
too much work if you ask me; stop trying to reinvent the wheel.
