Not much difference between a 2.6 or 16v gasser and a 2.5 turbo in torque, if you leave the turbo stock. Steve doesn't have any trouble with his overdrive turbo, except it's rather sluggish off the line with no torque converter and 2.65 final drive. In my case, I've got a 2.3-16 with Getrag racing box, the clutch will start slipping long before the tranny feels the strain. The reason the factory didn't make any manny turbos (or none that I know of, and certainly none for US market) is that you it can take a long time to get the boost going from a standing start without a torque converter, and you lose boost every time you lift throttle to shift. Autos can shift under full load. If you replace an auto with a manny, you will take longer to hit 60mph. I intend to port my head and adjust the ALDA accordingly. End result with a 2.65 final drive should be at least as quick as a 2.5NA with 3.07 final drive.
