Guest Anonymous Posted December 15, 2000 Share Posted December 15, 2000 What is the difference between the R-180 and the R-200? What year Z can the two types be found in? Do they all have the same gearing and how can you tell the two apart? Im currently looking at a 77 with a 5 speed What is the gearing in this car? Did they make different gear ratios for the same modle year Z- such as a 77 280Z with options on gear ratios Please let me know Im planning a Z project and need all the info I can get. ------------------ Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted December 15, 2000 Share Posted December 15, 2000 Thanks Pete. In your opinion witch is better R180 or R200? I will be installing a 350 with either a 5 or 6 speed. I should have around 350-400 hp. This will be a daily driver. ------------------ Quote Link to comment Share on other sites More sharing options...
Drax240z Posted December 16, 2000 Share Posted December 16, 2000 There is no question, with that kind of power considering a R180 would be sheer folly. Plan on going with an R200 from the start, and you won't have to worry about it again! ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html Quote Link to comment Share on other sites More sharing options...
pparaska Posted December 16, 2000 Share Posted December 16, 2000 What Drax said - definitely go with the R200. Of course it'd be best to go with a Limited Slip Differential (LSD), which came out of the 87.5-88 300ZX Turbo. Hard to find and pricey though, compared to an open R200. ------------------ Pete Paraska - 73 540Z - Marathon Z Project pparaska@home.com Pete's V8 Datsun 240Z Pages Quote Link to comment Share on other sites More sharing options...

I have read the many postings regarding LSDs. This may have been discussed, but I could not find it. 1)I know it is an expensive option, but what would be wrong with purchasing from Motorsport Auto the LSD assembly they have in the catalog for a '77 280Z, PN 22-4002 77-83 Non-turbo? 2) Would it "fit" without any modifications? 3) Does anyone know who makes the Motorsports LSD assembly?

Danno74Z Posted December 28, 2000 Share Posted December 28, 2000 As Pete mentioned above the turbo LSD is becoming rare, pricey and if you do find one chances are good its seen lots of miles with a clutch replacement due when you start hitting it with the torque of a V8. As an "alternative" below is a site you might find interesting and some prices for there LSD units. Get yourself some CV axles, pop them in to your new LSD and follow Pete's technical article on doing the LSD swap at the companion flange end and you should be good to go - both rear wheels. This is not a cheap alternative but the Quaife LSD is to my understanding bulletproof.

Guest Anonymous Posted December 28, 2000 Share Posted December 28, 2000 I assume the LSDs MSA sells are just NisMo LSDs repackaged or whatever. You'll still have to have a diff built, as the LSD assembly is only the gear carrier and the clutches - you still need a gearset, bearings, and a diff housing. And the labor to assemble it(and it's highly unlikely that you can do it yourself). The NisMo LSD assemblies are around $700 I believe. I'd get a quaffie if there was budget for it, it is pretty much wear-proof if taken care of, has no clutches to wear out, no viscous fluid to get old, and requires no special gear oil. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Mikelly Posted December 28, 2000 Share Posted December 28, 2000 ...and I got a price quote recently from MSA about gears... about $650 per set for my LSD R200... Not sure what they run for a regular R200... So factor that in as well! Mike Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted December 29, 2000 Share Posted December 29, 2000 Mike those shouldered 10mm12mm bolts are sounding better and better all the time! Actually, the cheaper later model diffs sound the best! Good ratios, strong, and they aparently damn near fall out of trees. Kripes, I wish there was one in front of me so I could see just how tough it would be to adapt. What's the sticking point, mounting or shafts?

Guest pauli Posted December 29, 2000 Share Posted December 29, 2000 can the r180's and r200's out of 4x4 nissan trucks be used? Quote Link to comment Share on other sites More sharing options...
