SellOut Posted April 27, 2017 Share Posted April 27, 2017 If I go up to 35's would I have to regear? If so what ratio would be best? I do less than 200 miles a month on the freeway so I'm not too worried about my top speed being over 75(as long as I'm not going 65 at 4k rpm) Sent from my HTC6535LVW using Tapatalk Link to comment Share on other sites More sharing options...
adamzan Posted April 27, 2017 Share Posted April 27, 2017 With the 3.5L you are probably okay. I would try the tires and see how it feels. Link to comment Share on other sites More sharing options...
hawairish Posted April 27, 2017 Share Posted April 27, 2017 If you've already got the 4.636 gears, that's the lowest you're getting. If 4.363, your only option is to jump to the 4.636. Link to comment Share on other sites More sharing options...
Citron Posted April 27, 2017 Share Posted April 27, 2017 Why not the 4.9s? Link to comment Share on other sites More sharing options...
mjotrainbrain Posted April 27, 2017 Share Posted April 27, 2017 Why not the 4.9s? From what I understand that only works in the rear diff, not the front for some reason. He could do 4.9's in the rear and an SAS with 4.88's in the front though! Link to comment Share on other sites More sharing options...
Citron Posted April 28, 2017 Share Posted April 28, 2017 Huh, weird. Nismo doesn't have taller gears for the r50? I think I can get 5 something for the wd21. Link to comment Share on other sites More sharing options...

Every other model uses standard cut gears, and there are front/rear options up to 5.14 available. 1 Link to comment Share on other sites More sharing options...
fixinto Posted May 8, 2017 Share Posted May 8, 2017 going up a few inches in tire size will simply make less rpm on the interstate at speed. less torque or pull at lower rpm range but it wont be drastic like you cant move or anything. 3 inches will probably give you somewhere around a 3.8 or 9 i know 1/4 mile guys that run 3.73 so you should be fine. back in the day of 3 speed transmissions 3.08 were common in the rear. short version you are fine. less rpm on interstate, speedo reading wrong.

Comparing old school v8 with a 3.08 and tall gears in the transmission is apples to oranges to a modern V6 with a 5 or 6 speed. Gearing is really based on an engines torque and hp curves.

neilca Posted May 10, 2017 Share Posted May 10, 2017 Why not replace the transfer case gears? I have seen gear sets for the TX10 for about $1200. Expensive but reduces the gearing front and rear at the same time. Link to comment Share on other sites More sharing options...
mjotrainbrain Posted May 10, 2017 Share Posted May 10, 2017 about $1200. Expensive That's why. It's also a lot easier to get at the diffs than they t-case. Diff gears shouldn't be very expensive if you can find a set of 4.636's at the junkyard. Link to comment Share on other sites More sharing options...
mjotrainbrain Posted May 10, 2017 Share Posted May 10, 2017 I also saw a post on my Instagram the other week from some company that makes Nissan truck parts (it's a big company, just can't remember what they're name is for some reason...I think they do a lot of WD21 stuff maybe?) and it said that they were selling reproduced NISMO gear ratios for R50's. Might be worth looking into if I can remember the company. Link to comment Share on other sites More sharing options...
