Early and late R200's

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 .

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
