Hey,

Is there anyone out there that are using a custom transmission with a close-gear setup? I've been doing a lot of research and think I've found a pretty good gear setup for what I'm going to be doing with the car. It is primarily used for auto-x and road racing. My new motor is a fully built sleeved turbo-d and should be easily making 250whp. Here's what I've come up with (D16z6)

1st gear: 3.083 (SPM)
2nd gear: 1.9 (stock ex/si)
3rd gear: 1.565 (MFactory)
4th gear: 1.25 (stock ex/si)
5th gear: 1.0 (MFactory)
F.D. gear: 3.722 (stock hx)

This is at 7800 RPM shift speeds:

1st gear: 43 MPH
2nd gear: 74 MPH
3rd gear: 90 MPH
4th gear: 112 MPH
5th gear: 140 MPH

And of course you have to factor if you still drive it on the freeways and higher speeds for long distances which was a big concern for me, I want to be able to drive it to the races.

65 MPH = 3620 RPM
70 MPH = 3900 RPM
75 MPH = 4180 RPM
80 MPH = 4450 RPM

This is the best I could come up with for an all around good close-gear ratio setup with gears that aren't hard to find. Any suggestions on this seutp. The other setup I was thinking was just changing the FD to a 4.9. I would like something to be an all around close-gear setup. BTW this is the gear calculator I've been using, http://www.autocrossing.com/cgi-bin/gearcalc.cgi. Does anyone else have one that's better?

Thanks,
