if you dont mind topping out at like 120 to 125 on the four speed i would use it. oh and also filling up with gas like every four days or so. (depending on highway use, and how hard you drive it) I personally like my four speed gives alot of ppl a surprise when you stage it and launch. but also i dont know how much the four speed will handle either.
.. and is this from personal experience? How many miles are you getting per gallon with your SC3800? I go a lot longer than 4 days with mine, but that is with driving it only 25 miles per day... maybe even less than that. As far as topping the speed out at 120 - 125, I am not sure because I only had mine in the triple digits once, and I backed off the throttle at 110, but still had plenty of throttle left. I will tell you that 110 is more than fast enough without other mods to vent air from the front end of the car.
Ask anyone that has something other than a stock engine mated to a 4 speed and you will know that the four speed will grenade itself.
Mine has not yet, but it should at any moment now.
On a serious note, if you want the best 1/4 mile times, stick with the auto that is stock with the SC3800. It is stronger than any Fiero transmission, and will shift faster than a manual.
Also if you want to go any smaller than a 3.4 pulley, plan on other mods like a cam, rockers, intercooler and the like to make the engine breathe better.
