[QUOTE=thecheese429;3926826]If you already have an auto in there, you could put the same money from a swap into building up the auto. Tight torque converter and aftermarket valve body, and you have a transmission that can stand up to the 12v once tuned. A built auto is inherently faster than a manual because they shift so fast compared to a standard which takes a while to shift.
I say that because I have a NV4500, and while I usually like manuals, this one is definitely not a "performance" transmission. It has synchro problems (either design or user error) so you can't speed shift without clashing, and for towing, good luck with 5th gear. Not to mention that if you tune up your 12v to gratuitous amounts of power/torque, you can snap a shaft just by rolling onto the go pedal (as I understand it).
I agree with this. I was considering the swap too but after i priced out a standard tranny, better clutch to handle the power and all else needed, i could have just built my auto up to handle the same if not more power. Figured that would save my left leg from pumping an aftermarket clutch all day when i had to make the dreaded drive to the city lol. I guess its all your decision though if you like standard and know what you are doing with swapping then it would be worth while.
