Z-Dreamer Posted November 30, 2018 Share Posted November 30, 2018 Question, I have a R200V Q45 FY33 – 3.692, will a S15 Silvia SPEC R Helical LSD differential work in the Q45 case and would I be able to use the Q45 gears and 6x1output shafts / stubs?

I've been wondering the same thing about the stubs. If yours are out, take measurements. I've got my S15 helical and stubs on my work bench and can compare.

260DET Posted December 28, 2018 Share Posted December 28, 2018 And so we have another 'I will do' fail. Quote Link to comment Share on other sites More sharing options...
Z-Dreamer Posted January 8, 2019 Author Share Posted January 8, 2019 No fail, I've just been gone for the holidays! I found out that the S15 Silvia SPEC R Helical LSD differential will indeed fit in the Q45 case. Unfortunately even though the Q45 stub axles are also 30mm and 30 spline, like the S15, you will have to use S15 stub axle shafts because of the difference in length, or modify the Q45 ones to fit the S15 LSD unit. Here is a useful site I found. Quote Link to comment Share on other sites More sharing options...
