Has any one attempted putting a 3rd gen twin turbo 13b in one of our first gens, i have heard of it being done but i have never seen one.

 

There are one or two here that have done it.
The TII swap is FAR easier,cheaper and can be just as powerful with a few mods.The REW swap is unique and would be very responsive but itd also be more abusive to any FB drivetrain components you retained, due to its lowend torque output.The TII tends to be more forgiving since its torque doesnt hit so hard and low in the revs.
