Lotus7 Posted October 20, 2005 Share Posted October 20, 2005 I am doing conversion from 1977 Z to Rb26dett. I got the engine in the car. I have an Rb25det tranny. I have to make my own driveshaft. Can some help & tell me what driveshaft spline I need? Is the spline of 240sx or the 300zx TT will match the Rb25 tranny input shaft?

Guest JAMIE T Posted October 20, 2005 Share Posted October 20, 2005 300ZXTT is the right one. Quote Link to comment Share on other sites More sharing options...
Lotus7 Posted October 20, 2005 Author Share Posted October 20, 2005 300ZXTT is the right one. Jamie....appreciate your help. Thank you very much. I will try to buy a used 300zxtt driveshaft and cut the spline and give it to the custom driveshaft builder so he can custom the length for me. Again thank you.

J Taylor Posted October 20, 2005 Share Posted October 20, 2005 Any shop that does driveshafts should be able to get the yokes for you. I had mine made locally and all they did was count the splines. JT Quote Link to comment Share on other sites More sharing options...

Ed260Z Posted October 20, 2005 Share Posted October 20, 2005 300ZXTT is the right one. Couldn't you just take the 300ZXTT driveshaft to the shop, and have them shorten that one to fit into the S30? Or is there some reason why that shaft would not work? Quote Link to comment Share on other sites More sharing options...
AKWIKZ Posted October 20, 2005 Share Posted October 20, 2005 The '87-'95 Hardbody and Pathfinder V6 manual 2wd use the same yoke as well. Just to open up some options for you. Brian Quote Link to comment Share on other sites More sharing options...

J Taylor Posted October 20, 2005 Share Posted October 20, 2005 Not sure why I didn't mention it before but I am going to be selling my rb25 transmission and driveshaft soon, as my th350 should be in the mail right about now. Want to try to sell them together first but I may end up seperating them. JT Quote Link to comment Share on other sites More sharing options...

Guest JAMIE T Posted October 21, 2005 Share Posted October 21, 2005 Actually, what I did was buy a racing one piece ZXTT driveshaft and I will have IT cut down. I did this because it had the correct yoke and flange for the ZXTT diff I am using. It has high quality u-joints and is real nice. Quote Link to comment Share on other sites More sharing options...

Just for records: I found out the correct yoke (spline)using RB25det tranny is from Nissan Truck Pathfinder. Quote Link to comment Share on other sites More sharing options...
Lotus7 Posted November 7, 2005 Author Share Posted November 7, 2005 I was able to install my Engine (Rb26) and also positioned my Rb25 transmission. Took me two days plus the fabrication of the tranny support. Thanks God, that thing is done before colds comes. The stock clutch slave cylinder from the Z is different mount and it will not bolt to the RB25 tranny. Any other clutch slave cylinder that I can use that is available here in the U.S. ? Is the 300zxTT clutch slave cylinder will work? Thanks Quote Link to comment Share on other sites More sharing options...

JT I asked you about it in another thread, but you didn't respond. I hear Pete has first dibs =P. I don't need the tranny but the shaft would be nice if you want to part.

J Taylor Posted November 8, 2005 Share Posted November 8, 2005 240Z_Master: Pete is talking about getting the tranny and shaft and if he does then he will get dibs. If not and they get split up, Joel has dibs on the tranny if he decides he wants it and I think you were the first to ask about the shaft......pretty sure.

JT[/quote'] Yeah, I just need the shaft. If Pete needs both let him, and if Joel wants the tranny, I'll take the shaft (pending price that is). But yea, no worries mate.

Matt (motorworx) is in japan and gets pretty good price foe it/.... if i remember right a new will cost around 12000-15000 yen. once you have one the 300 z slve rebuild kit will work.
