will a series 4 engine fit perectly in a series 4 car and a series 5 in a series 5 car. how much must be done to transplant

 

Yes and yes, povided they are both TII's to start with. To transplant, remove the wiring harness and unhook all the lines from the old engine. Remove the old engine. Remove the partial harness off of the J-Spec (If you buy it from us) and install the J-Spec into the car. Reinstall your harness to the motor and install the lines and you are set.

 

thanks alot fc3s
