question
 

what can i do to my auotmatic transmission to get it faster without putting a 5 spd. if i put a r200 3.90 diff in it will it be quicker or will that only work with a 5 spd

Re: question
 

normal engine mods will make it faster, headers intake etc. I i'm not sure about the diff, but I see no reason why it wouldn't work. Could cause problems with cruising.

Re: question
 

shorter gears equal better acceleration but worse gas mileage and lower top end speed. For every 1 turn your wheels make, your drive shaft will make 3.9 turns with an r200 3.90 gears. you will also top out in each gear at a lower speed than before. but yes, you will be quicker. if all you're planning on doing is swapping gears, then swap in 4.11 gearing

Re: question
 

Modifiying the transmission to shift harder will increase your acceleration as there will be less power-loss during shifts. A slightly higher stall speed will also help out, but a the expense of more initial 'take-up'.

A _mild_ cam will also help, but you may find that you lose power if it's not installed & dialed in correctly.

A shorter diff will probably help the most, what ratio does it have currently?
