I gather why gearbox mount, crossmember lined up on one car and not on the other, is the car the RB25 gearbox conversion was done on in first post, looked like it had a autotransmission in the past and was converted to manual. Why I think this, is they make holes for autotrans shifter that mounts on top of hole where gearstick for manual transmission goes and the holes are still there in the photo.

With auto to manual conversion on a R32 auto chassis, I think you need a S13? crossmember for rear gearbox mount. So the mount holes are in a different place on chassis for autocar (transmission might have been longer??). Maybe a R32 auto crossmember that's designed for a longer gearbox might have made it line up on the factory manual chassis or maybe S13 crossmember??? Also you can change the yoke on auto driveshaft for a manual yoke.

So i finally got my transmission and wondered about the r33 rb25 trans in the 20's place. I am wondering about the speedo sensor from the gtr, is there anything out of the ordinary stuff that needs to be done?

Also the cross member that will be used to hold the trans up what have you guys done to make this work will your previously manual cars? Anyways feel free to let me know as it will be a big help!

Thanks,
Chris

24. You CANNOT use the speed sensor of the RB25 since its electronic and RB20 uses a mechanical system. You need to get the one for the GTR. There is an info thread on this subject elsewhere.

I need help for this, anyone can PM me?
The GTR speedo fits in the RB25 tranny?

Thank you!
