Hey all

looking at diffs for my r33 gtst series 2 track car.

The car is mainly for 200 meter runs. But also mucking around at drift stuff.

So im after grip and heavy acceleration!

Whats the ratio of the standard diff?

What would you recommend 1.5, 2way etc?

And what ratios for flat out acceleration?

Plus strength

cheers

Yes keep the housing.

If you get a Cusco one you can adjust it all the way from 2 way to 1 way according to your preference but most people seem to go for Nismo. Or you can get a 2nd hand GTR diff but then you have to make changes to suit the 6 x 1 bolt pattern.

Hey guys had a 2-way in my 32 and kinda got over the clunks/jerks and now looking to put the power to both wheels in the 33..

I'm unsure what to do with a stock auto diff.. do I still have 1, 1.5 way options in the ratios the auto uses?

Also it will have a shift kitted box with 250+, so I'm guessing a shimmed diff wont like that power for long. Trying to maintain good drive aswell as being able to have both wheels putting power down.

1/4 mile and cruising only.

sounds like your ideal diff would be helical. But that's another kettle of fish finding one. They did come in late model R34 manual turbos but rare as f**king hens teeth and wreckers wouldn't know one if it hit them in the head.

/\ ive found a S15 helical 4.08, which is a swap over using s15 6-bolt shafts also..?

I did that to my R32. Put it into R32 housing with R33/4 4.11 gears and S14 half shafts and driveshafts. It's a real bitsa, but it works. The only downside will be if I start finding the strength limits of the 3x2 bolt CVs.

      Weird compression after rebuild

      By dbm7 · Posted

      Yeah. air pressure leakdown test is where I would be headed next here, using one's ears to determine whether it's the valves or bores/rings leaking...

      More likely you didn't bed the rings in correctly and have glazed the bores. Running with misfires on a fresh build is somewhat of a no-no. Surely no-one "smoke tests" the combustion chamber? That's what a leakdown test is for. Smoke testing is, um, a bit of a wank at best, and only really useful for external pipework.

      Attesa pump mount options / ideas? R32 gtr style.

      By GTSBoy · Posted

      Well, obviously that kit is not a relocation kit or anything other than just the original isolators and the like. I would suggest that it should be a matter of just bending up some flat bar to build a mount over the top of some other diff, with the flat bar held to the back of the diff by the rear hat bolts. A little welding, a little thinking about how to secure the front of this structure, maybe some different hoses in case you can't get it in just the right place.

      Can you mount the ATTESA pump in other locations?

      By GTSBoy · Posted

      Pay diff/trans workshop to do this.   Nope. Z32 turbo ran R230 with 6 bolt GTR style axles. All other Z32 were R200. Basically same same as other R32 stuff. All were a viscous waste of space.

      So, I'm not a diff swapsies specialist, but I am pretty sure the 300zx ran an R220 not and R200 like the C34 Stagea, so I think it is of no use to you. As you said, all you need to do is get the centre swapped in the diff you have, which might be best done by a diff specialist. The current centre is probably desirable to someone to track so an easy path might be to swap your mechanical centre for someone with a standard centre (which is a viscous LSD, and almost certainly won't have any limited left). The only thing you have to watch swapping R200 internals between diffs is that the number of splines on your car's stub axles has to match the donor car, or you need the centre+stub axles and make sure they have the same number and pattern of bolt holes as your rear axles.  You swap your current ratio onto the new centre so you don't have to worry about matching the front. Alternatively, centres like the Nismo pro are much gentler (and have adjustable "tightness") so you could buy on of those from somewhere like Jesse Streeter or Nengun (noting it may cost you 1234% extra in tariffs by the time it lands)
