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...

      High temp brake fluid?

      By Komdotkom · Posted

      This has been covered a bazillion times but google wet boiling point vs dry. Motul is only good when it's fresh, once it absorbs moisture it gets pretty average very quickly. So as above, make sure you change it if you're going racing. I run the Endless brake fluid in mind, but only because a mate is a distributor and it's cheap. It's not quite as good as SRF but I'm running 380mm rotors on a Skyline so it's not like they get hot.

      Does 98ron contain ethanol?

      By Kinkstaah · Posted

      That's the thing, they still add it and it makes fuel cheaper, implying adding 10% of it drops the cost of 91 by what, 5c a liter? I remember when it was barely half the price of 98. Because you know, 85% of what is in the fuel is way cheaper than 91 fuel is by volume.

      Need AC Compressor for R32

      By GTSBoy · Posted

      Auto electricians that do repairs on automotive AC systems can source service kits. I don't know where they actually source them. I do know that there is one available for the R34 comp that I would need it for. If you have to pay someone to dismantle, clean and do needed repairs and fit kit contents, then you'd probably end up spending a good fraction of the cost of a new one. I would not be paying for that, because I would be doing it myself. My mechanic (bro-in-law) will happily source what is needed. Back in the day (like in the 80s and 90s), rebuilding an AC compressor was the standard approach, same as for starter motors, alternators, etc, because new replacements were v. expensive. After the China manufacturing boom and the rise of the disposable approach to everything, people just started throwing broken/worn stuff away and not rebuilding things.

      Is rebuilding it even a thing? Where would the shop find parts for it? I looked at some off these local online stores for my r34 and suprisingly they had brand new aftetmarket ones for $600-800 I think. I guess r32 might be a bit tougher.

      I remember the days when E85 was priced in according to the $ per km outcome. Sure E85 was about 35% cheaper, but you also lost about 35% range... now it's fked..
