Bumper will not fit, and stock numbers for HPand Tq are 155HP and 160LB-Tq. In actual terms it is usually 130RWHP and 135-140LB-Tq. The Ka is a very good canidate for building up. It is strong and with the displacement it gives good amount of torque. If you plan to turbo this is a good combo and there are plenty around to prove it...
