Hey guys,

I have done a few searches on this and have found out some info but am confused by some aswell, Through a twisted chain of events my r32 GTR has got a standard 4.11.... diff in the rear, and now as (completely installed) what appears to be a 4.364 diff in the front. NOT GOOD!

We are not exactly sure which diff it is in the front but from turning the shaft and counting rotations that what mechanic estimated it to be, around that.

What I was wondering is

1. Rather then change the fron diff, should I just leave it, and replace the rear.

1a. is there many compliactions with doing this????

2. Is it possible to switch the front diff without ripping engine out???

3. If the mechanic reckons the front diff ratio is around the 4.5 mark is there any other ratio diffs that it could be, regardless I he is gonna get in and have a look on the crown wheel, I'm just trying to see if I can start trying to source a new front or rear

If anyone has got an incite into this problem that would be a great help,

cheers guys

AsH

you really need to get in there and find out what the exact ratio is of the front diff. a common swap is GTS4 diff which is 35:8. if this is what you have in the front then I would suggest hunt down a GTS4 rear diff and use that crown wheel and pinion with your current GTR centre in the rear. then you'll have the same GTS4 ratios front to rear. if it is actually 4.364:1 I have no idea what it could be out of. I can't even think of a CW/Pinion combo that would give a ratio of 4.364. I would say it's most likely the GTS4 diff he just did some bad maths. :P

If i remember right the 4.3 final is the same final they used in the GROUP A GTR in japan, i've seen a few for sale on yahoo label nismo group a or nismo n1

group A cars used lots of different ratios all custom. they may have used a 4.3 for some tracks, but again I don't know what Crown wheel/pinion combo would give an exact 4.3 ratio.

ok..

Im re-hashing an old thread so as I dont have to start a new one.

I have an R32 GTS4 standard diff - 4.375 Diff ratio - Yes?

And is this an open diff?

Now, Im using it for drifting and im looking for a a cheap LSD.

An R32 GTR is a mechanical 2 way. Yes?

4.111 diff ratio - Yes?

Now, R200 refers to the crown wheel - 200mm - Yes?

Is an R200 diff a GTR diff?

What is the name of a GTR (Non - Vspec) LSD Diff?

Could I get a GTR diff center and drop into my housing?

Using google for "r200 GTR diff" I found some results and this site: http://forums.nicoclub.com/zerothread/243052 advises the casing's are different

All I found was "R200" diff and that its the shortnose version...

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
