I remember seeing a gear calculator on the forums where you type in some numbers and it tells you what size gear you have...i tried the search function and could not find it. I would really appreciate it if someone could find it for me..im just making sure i have what i think i have because i dont want to get new gears and have it be the same. Thanks.

 

RPM=(336*ratio*MPH)/TireDiam

Ratio is the current drive ratio combining the tranny and rear end ratios.

 

Yikes, all that was kindve confusing. At 2K RPMs in first im at 15 mph with stock tires (not sure of tire diameter, 17 inch rims with maybe four inches on either side??? dont really know) is there anyone that could tell me the rear end gears??

 

Actually...i think i found the calculator, but could someone give the gear ratios for a manual (t-5??) I think its a t5, its stock on a 94 gt. THanks.

 

You can figure it out using this calculator if you work backwards. Enter the tire size, enter the tranny, enter the speed, enter a gear (like 3.73) and see if the speed matches up with the RPMs for your particular setup. Then depending on the RPMs you cna change the gears up or down until they match. Should take less than 60 seconds to figure out what you have.
