i have a 1990 gxl with a bad motor and a 1988 vert and i know the gxl has a 4.1 rear and the vert has a 3.9, can i just drop the whole pumpkin and swap them or do i have to open them up and change out the gears???
also will turbo 2 injectors work with the N/A fuel rail???
thanks
tommy

 

The diff should be interchangable, though your speedo and odo will be off.
The T2 injectors won't provide the right amount of fuel to your car. They already run rich and those will just make it worse.

 

i was looking at racing beats web site and they state that if you run a true duel exhaust with 550cc secondarys you can get a 15 to 25% power increase.
