I did the math ratios and here is how went (calculations are with FD multiplied in)


KA / FD of 4.093
1- 13.559
2- 7.765
3- 5.340
4- 4.083
5- 3.098

Z33 / FD of 3.54
1- 13.416
2- 8.227
3- 5.735
4- 4.496
5- 3.540
6- 2.796

Trans swap
Z33 / FD 4.083
1- 15.474
2- 9.488
3- 6.614
4- 5.185
5- 4.083
6- 3.226

LMK if you find any errors in my thinking. Gear ratios is new for me.

It seems its going to Accel faster and possibly use a bit more gas in top gear even with a 6th. So I think after having a little fun with the more acceleration I'll have, Im going to swap out the FD for something a bit longer.

Doesn't the J30 diff have a longer FD? what car has a 3.7 FD?

I'll make a post about the project when I start it sometime later this month.
