Here are the gear ratios for the P10 G20 and the NX2000

P10 G20

1st 3.063
2nd 1.826
3rd 1.207
4th 0.926
5th 0.733
Final Drive ratio 4.058:1
Reverse 3.153:1

Nx2000

1st 3.333
2nd 1.826
3rd 1.286
4th 0.975
5th 0.756
Final drive ratio 4.176:1
Reverse 3.153:1

I am wondering if when I install an NX2000 tranny into a P10 if these ratios (NX2000) will make any performance improvements.
Could be a stupid question but I'm only good at installing parts the numbers screw me up sometimes

Yes, the NX box will improve the performance. The ratios are shorter which will help with acceleration.

You can! I am going to post all the details and maybe even some pics. This will be the second conversion from auto to manual that I will be doing on a 93 P10 except this time I could only find a tranny from an NX2000...G20 parts are hard to come by here.

Thanks P10DET for the info about the ratios. Should be interesting to see. I guess if it gets better acceleration I better swap out MY tranny too Lucky me I got a G20 tranny for mine.

It looks like the NX2000 tranny only helps if you take your car to track or do lots of highway driving. The advantages are only really noticable above 100 mph and in acceleration from 50 mph.

Your right about that. The NX box gives considerable power on the high end which has yielded an obscene stock top speed. I do want the car to have this cuz I intend to do a little more "professional" racing. Low end will need some work but it's nice and I am satisfied.

And for us canadians Posi trac will be indispensible if I use the car this winter.
