Diff Diferances Na-turbo

well as it so happens, i was an AE86 drifter for many a year.

My AE86 had a Toyota Racing Development 2way LSD and about 85 kw at the tyres. The difference being that it was a live axle arrangement. My 86 was very oriented toward going sideways rather than going fast. And therefore a flick of the wrist in 2nd or 3rd gear would result in a drift being initiated. This was more to do with the pinion angle and the rose jointed rear end than the diff.

If you wish to go fast point to point, even in an NA skyline, first spend your money on some 9 or 10 inch wide rims and good tires. I firmly believe a viscous LSD from a turbo skyine will be adequate as your unlikely to overcome the ability of that diff with NA power. But if you can get that 1 way mega cheap, then get that.

from what i was reading earlier in this post, why would you want to change to a turbo vlsd diff, the diff in my na at least is a vlsd na diff, with the shorter ratio it will accellarate quicker and its still the same viscious lsd set-up.

Definitely..

Run decent tyres with VLSD and you can get away without having to run a better diff. Run crap tyres that break loose easily and it will single spin and just not hook up.

i already have a set of track rims with 255 tyres, and have some semi slicks in the pipeline as my wallet allows me.

thanks for the insight andy - looks like i'll be making some enquires into this diff.

some na skylines didn't come with an lsd - so swapping to a vlsd using their standard crown and pinion to maintain their short ratio is an upgrade.

Depends what you mean by Na diff...

An R200 is an R200 all the same strength.

The diff centers, one being the weaker N/A the other being the tough but single spinner VLSD and in the GTR's case Mechanical clutch LSD.

So either way your going to have to spend another couple hundred having a diff specialist (Boss Automotive here in SA) setup the ratio with your LSD, he also shims up the vlsd crap while your there.

I have a 4.363:1 ratio for $100. So it will be a 300-400 exercise to swap ratio's with backlash etc all setup nicely.

hey i own a 1992 r32 type m gts25 and i dont think it has a lsd but anyhow its starting to make clicking noises when taking off gently from first and also in reverse, im wondering how bad this is and if ther is a solution for it, it doesnt help that the idiot at the tire shop put 245's all round from 215-225's, i was thinking of swaping with a gtst diff but now reading this with the ratios maybe i ought to find a na lsd 1.5?

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.

      And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.

      No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.

      Ahh. Well the block damage is a problem, you really need to run a tap or thread chaser through it to see if the threads can be saved, but any chips are likely to be bottom end bound which is bad. Earls seem to have what you need if you want to stick with mounting direct on the block: https://rceperformance.com.au/parts/earls-straight-adapter-1-8-npt-male-to-1-8-bspt-female.html, but as I said above I'd recommend remote mounting the sender

      I'm not quite understanding or I'm missing steps here, (I appreciate people are trying to inform my brain but I am of the dumb, especially today) - All I want to do is mount the male BSPT of the OEM sender into the system somewhere without it snapping the adapter via vibration. The Nissan sender has a male 1/8 BSPT output. The block has a (very destroyed) 1/8 NPT input. I'm not really sure how a lathe assists with that, and also don't know anybody with a lathe, nor specifically what I would want to buy. I'm not really sure how adding additional adapters creates a better, more leak proof resilient seal here.
