The FWD Galant Swap should be simple. it will use all stuff from an Eclipse or Talon. they have the exact same subframes. all the mounts will work and axles from an eclipse. you will need to do some extra wiring before a 91-94 turbo ecu will work in that car. need to wire in the injector resistor box for the turbo injectors. need to add wires for knock sensor and need to wire in the extra wire for turbo MAS. the rest is just drop in the motor and go. ..... this all on the assumption of the Galant you swap is a 2.0NA... if its not then just get a wiring harness from a T/E/L
