xx.jason.xx Posted April 10, 2006 Share Posted April 10, 2006 how strong is the 350z tranny and will it mate to an RB26? I really really want a 6 speed and an RB26 in a 240z and am looking for a good combo.... Quote Link to comment Share on other sites More sharing options...
mtcookson Posted April 10, 2006 Share Posted April 10, 2006 The 350Z 6-speed, from what I hear, isn't all that strong. Any particular reason you want a 6-speed? If you absolutely want one you could go with a T56 with a custom bellhousing. Might check the gear ratios though to make sure it matches the RB26. You might have to go with a Cobra T56 as it has a .62 or so 6th gear compared to the GM T56, which uses a .50 6th gear. Depending on your rear end, that .50 top gear could make the rpm too low for the RB to be able to cruise efficiently. Most importantly, you need to make sure the gear changes are within the RB's power band. If the rpm drop is too much it'll be slower than having a good 5-speed that matches the RB. The T56 should work pretty good... but double check to be sure. Here's a good page for calculating all of that: http://www.geocities.com/z_design_studio/transmission_300zx_tt.html Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted April 10, 2006 Share Posted April 10, 2006 There is a kit that sells an adapter plate to mate a supra 6 speed to the RB 26. Do a search in the RB forum and you could find it. Quote Link to comment Share on other sites More sharing options...
BirdmanZ Posted April 10, 2006 Share Posted April 10, 2006 castlemaine rod shop is the company that sells the adapter to mate the supra six speed to the rb26 Quote Link to comment Share on other sites More sharing options...
xx.jason.xx Posted April 11, 2006 Author Share Posted April 11, 2006 I emailed Castlemaine about the adapter and they said they dont make an adapter or a bellhousing for that combination, hence the question... Maybe I got someone who didnt know what they were talking about. Quote Link to comment Share on other sites More sharing options...
xx.jason.xx Posted April 13, 2006 Author Share Posted April 13, 2006 Interestingly enough, I have found that both the R34 GTR and the 1993-1998 supra use the Getrag 233 transmission, which makes me wonder how the power is transferred to the front wheels in a skyline. I cannot find a photo of a skyline transmission, and therefore cannot find this answer... Quote Link to comment Share on other sites More sharing options...
