Rb25 Gearbox Conversion

[filo_a31]

Can someone who has done this conversion please tell me how long the tailshaft ends up being so i can cut and weld the rb25 yoke onto the cefiro tailshaft?

not sure on lengths, but I was able to simply swap the yokes over to suit... length wasn't altered I dont believe...

oh ok, i was told that the rb25 box is longer than the rb20 box, so i thought it would need to be shortened

i think the rb25 yoke is shorter, so you just need to bold the new yoke to the cefiro tailshaft.

i think off hand mine ended up being 10mm shorter basically where they cut off the 20 yoke and slipped the 25 yoke back into the shaft.

If car has ABS it will have to be shorter, ABS diff has longer nose (GTR not included) from my experience.
