Early and late R200's

[discopotato03]

I got some links from the forced induction section on the internals of short and long nose R200's . They say the carrier dimensions are the same but the crown wheel bolts are larger again . I know that R200's DR30 style can have 10 or 12mm crown whee bolts (turbo or non turbo according to the Nizmo catalogue) but not sure about the later short nose variety . Anyone been inside them and know what they use ?

Cheers A .

Did some research and found that the late short pinion R200's use the same carrier dimensions as the early ones . The crown wheel bolts may be larger but this is easy to fix . They can be drilled as the crown wheel locates on its inner bore not the bolts themselves . Lots of options ie Torson 3.692 (manual S15) for RB31DET in R32 .

Im pretty sure you have to use the gears off the long nose onto the short nose centre when used in a long nose housing but dont quote me on this.This is normaly done by using some sleeves so the smaller bolts fit snug in the short nose centre.Im pretty sure the torsen diff uses 13mm bolts.

I would use the S15 differential complete in an R32 if it fitted . I can't think of any logical reason why Nissan would change the pinion offset for the late R200's . I think you'll find the late ones are short because of the cradle type multilink IRS vs the semi trailing arm IRS with its cross member . Obviously pinion support on the short version is not lacking if GTS25T / GTT and GTR performance is anything to go by . I have a DR30RS 3.9 LSD with a good centre and wanted to know if it fitted the short type R200 . The 3.692 (3.7) would work well with the 3100cc's low down torque .
