Best gears for 2.0L N/A.

I'm planning an LSD in the near future and was thinking about going to 3.94's when I do the swap. I know going from 3.55's to 4.10's in my truck made a huge difference in acceleration, do you think it'll be the same for the Neon or should I just stick with 3.55's? I'll be running at the local 1/8th mile track. Thanks.

3.94's will help a lot in the acceleration department. You will also loose some in the MPG department.

seems like N/A people go with 3.94's and turbo people go with 3.55's

Same as N2O guys run higher gears as well. Guess the extra boost from the turbo or N2O helps to add torque so they don't need to multiply it as much. Before I do any other mods I really need LSD and gears along with a light weight flywheel so I can run a non-modular clutch and pressure plate. That way I can change out clutch discs and not have to buy a new pressure plate if it's ok. Where do ya' think I can find a set of 3.94's for the T350 MTX?

The reason n/a cars run the numerically higher gears is because they typically rev higher and don't run out of gear at the top end due to revving higher. Turbo cars are tyically lower-revving and with a numerically higher gear will run out of gear before crossing the traps.

The more torque you have by Turbo or N2O the less gears you need. On an N/A car you have to multiply the torque more because you don't have as much pressure so you don't make as much torque.

this is about transmission, so I will move it to that thread...
