I hav naffed my gearbox in my S2 ESRT, and have been offered a FRST gearbox, will it go straight on and be ok with the S2?

 

the box will fit without 2 many problems but the frst doesnt have a limited slip diff. if your car as more than standard power, your'll struggle with traction not 2 mention torque steer. i wouldn't advise it mate.
