i have taken apart my my rb26dett transmission and did a bell housing swap but i am wondering if it is possible or worth changing all the gears from the rb26 trans to the z32 all i have really found is topics about rb25 z32 swaps that go that deep in to them

Just want to be clear...

You have a RB26 Bellhousing on a Z32 Trans case correct?

Both are FS5R30A's...

Z32:1st - 3.2142nd - 1.9253rd - 1.3024th - 1.0005th - .752

GTR:

1st 3.214 2nd 1.925 3rd 1.302 4th 1.000 5th 0.752

I understand the input shafts are slightly different in length but not by much with a 25 so I'm not sure about the 26 but wasn't an issue going buy the guy's post below:http://forums.hybridz.org/showthread.php?t=119041

Hope this helps...

Might consider a spacer plate (have one cut with a water jet... shouldn't be to expensive depending on how well you can source the material/labor)... just make sure you have enough thread length and don't make it to thick...

Let me know if you need help finding a water jet or material...

the input shaft thing has been covered 10x over.

Just bolt it together and be done, its no big deal.

Not if you keep the same tail section on........the linkage setups are completely different
