johnc Posted December 7, 2008 Share Posted December 7, 2008 Spend some time reading the Drivetrain section on this site. Its all been discussed before and there are lots of examples. Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted December 7, 2008 Administrators Share Posted December 7, 2008 Here is a hint. This pic is real, no photo-shop. Nitrous, dual quad, supercharged small block and this R-200 diff is stock, other than welded spider gears, and runs 9.2 @ 153 MPH! The half shafts are your weak link, and being semi trailing arm rear suspension that weak ink is exaggerated. Stock Datsun Half shafts were used in that car pictured above and did hold up, I seem to recall they did bust a few, though the JnJ boys spent some time to be sure there was no angularity of the U-joints during launch, (that is the secret to getting the half-shafts to survive abusive launches, which is more difficult with the ZX semi trailing rear suspension). Those gentlemen that own/race that Z eventually upgraded to the 300ZX CV half shafts. Hope that helps. Quote Link to comment Share on other sites More sharing options...

woldson Posted December 8, 2008 Share Posted December 8, 2008 U-joint axels or cv? That car has cv conversion if memorie severs. Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted December 8, 2008 Share Posted December 8, 2008 IIRC it had ujoints at the SEZ that I went to cause I saw them change them out. I think they would get only a few runs on the ujoints before replacing them. Later I think they converted it to the CV's. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted December 8, 2008 Share Posted December 8, 2008 I found that the stub axles on my Zcar were the weak link. I would brake stub axles regularly at the track. I am currently running a beefed up R200 LSD with CV axles and MM 39 spline stub axles. My car is nowhere as fast as some of the others, it runs 6.40's at 110 in the 1/8th spraying a 175 shot at the 60 ft. mark. Quote Link to comment Share on other sites More sharing options...
