Thread: g20 gear ratio

Is it just me or does the g20 transmission have a super tall gear ratio? Going 70 i am at around 3400 to 3500 rpms is that normal? I have it bolted to a sr20 in my b14 with 205/45/r17s. When i had my ga in the car i did 70 at about 3000 rpms. I feel like im losing a lot of highway mileage because of the rpms.

What year G20 transmission is it?

I believe it's a 2000. It's a LSD too if that helps at all.

Its longer than any se-r tranny. Click the link at the bottom of the first post once you open this link.

Ya I actually looked at that before I posted this thread. Would that minuscule of a difference in the fifth gear make a 400 rpm difference? That just seems crazy.

keep in mind the tire sizes on the chart and on your car may be different.
