You guys are pretty on top of correct info, so here it is set to the experienced. I have two r200's out of a 76 and 85 both being 3.54 and found out its not going happen finding 3.9 r & p gear anywhere. At least I have the turbo cv shafts now . So now im on the prowl for a 3.9. My 260z late model is going be cruise, fun, proud car to own, not track or drag. It's going have the ls1 t56 or auto tranny. I see that one guy has a pretty cool bolt on set up for a ford 8.8 irs but going keep an eye out for a r200 for now. May even just grab a 80-83 MT NA r200 pumpkin being they are all 3.9, just not an lsd. ....So here is my question. I have read sites saying the r200 ratios for the 87-89 300zx NA being 3.9 and the turbos being 3.7 lsd...as the link from this site send you. Another site says they are all 3.7. The 4.11 would be fun but might be too much for what im going do with it. I realize i can just pop every cover off every one i see in the yard and check numbers on gears, but rather not until i think i have the right one..lol Save me from the insanity.
So I've reached a point where my research capabilities are failing me. I want to use an OS Giken Superlock in my longnose r200 (I know there is some mention of bushings to match bolt sizes? Not sure, but my diff builder said it was no issue). I know they have one for the 240Z R180, but there is no specific mention of one for the R200 from the 280Z. Are there any other long nose R200s that are identical such that a posi made for it would work in my current housing? I will be running the AZC suspension/brakes all around, 19 inch wheels in the rear with 305/30/ZR19 Hankook RS3s. Thus, I am also trying to figure out which rear end gear ratio to use. I'm rebuilding this diff right now and I want to do it right the first time. I should be making around 600rwhp (HCI LS7). My plan is to use the 2.66, 1.78, 1.30, 1, .8, .63 T56 Magnum (I think the taller 1-3 ratios will help with traction). The car will be a fun HPDE car for road courses, but will make the occasional trip to cars and coffee (Performance is more important than low cruise rpm). The car will not see the drag strip. I know all of this requires a stout rear end setup, so I figured the OS GIken + AZC setup would be a good start. Any other recommendations are welcome. Not sure exactly how crazy I need to go axle-wise to avoid issues. Thanks in advance for the help -- I'm trying to do this once and do it right!
