240Z2NV Posted April 24, 2005 Share Posted April 24, 2005 I may be mistaken, and if so I welcome any clarification, but the axles are much smaller, the housing is smaller, I don't think that it is 'Viscous', and the gears are smaller (in heft)......

Guest zfan Posted April 24, 2005 Share Posted April 24, 2005 Clive, An r200 LSD with 3.70 gears is found in the 1987, 5th month to 1989 300ZX Turbo's only. You can't miss them, they have an aluminum finned rear diff. case/cover. If you find one in the bone yard like I did mine they can be had cheap. I paid 90 bucks for it with cv axles. If you go searching on Ebay you can pay 400-600 bucks on average. Mike Quote Link to comment Share on other sites More sharing options...
EvilC Posted April 25, 2005 Author Share Posted April 25, 2005 Thanks guys for all the info. I am about 90% sure I will go with the 94 Q45 VLSD 3:54:1. This is going from the info I got from MAS280. I guess my next set of questions will be about cv's and such.....but I will search first before I ask. A fair prive from the junk yard for the whole rear end unit should be under 200 dollars right? PS. I still dont know how to put the faces and animation into my theards =(..I don't wanna make faces anymore with the keys. LoL.

maichor Posted May 2, 2005 Share Posted May 2, 2005 It looks like it is all correct to me. I have a 3.54 R200 Q45 VLSD diff sitting in the garage. I have new seals for it. I was about to junk it. It sat open in the rain at JY for who knows how long and turns alright once you break the rust loose. I clean out the garage this weekend for the move. Does anyone want it?

Corzette Posted May 15, 2005 Share Posted May 15, 2005 Back to R200 ratios. I have ran the 354 and a 411. With these cars there is no need to worry about a 354 vice 370 unless you just want more top end. Tire size will tune that ratio as well. I was running a 411 with 27 inch tires and crossing the traps at 6000 RPM in third running 11.97/8s with 1.60 60s. I switched to a 354 R200 and went a best of 11.91 with two 1.59 60s but only crossing the traps at around 5600/700 RPMS Depends where you want the power to end up I guess. If you run an open diff there is no problem hooking with the right tires and suspension but you will eventually break the pin in the diff after 50 to 75 runs if your at 375/400 RWHP. I love the open diff and am looking at a way to fab a 4340 solid steel pin to replace the current ones. The pin seems like the weak link in those diffs but a cheap fix if I can find a way to fab them..... Terry Quote Link to comment Share on other sites More sharing options...
maichor Posted May 16, 2005 Share Posted May 16, 2005 My guess on shipping would be ~$50. Quote Link to comment Share on other sites More sharing options...
