I am thinking about buying an R200 R33 viscous diff to put into my S2 Stagea, which doesnt have an LSD, one question, as the ratios are different, can my gears be swapped onto the LSD centre so as to keep my original ratio ? cheers

yes.

I'll be doing the exact same thing when I can get around to it. I have a spare 4.1:1 S14 Q's diff,and an S14 Viscous centre sitting here spare.

I'll only need to swap the diff cover out of the wagon,and use my driveshafts.

my ratios in my stagea were 4.3 and gtr diffs are 4.11, they are interchangable, and i installed the gtr internals into the stagea diff housing so all the attessa pump brackets remained as gtr have theres mounted elsewhere. the gtr and stagea housings are identical in size/shape except the mounting points for the pumps, etc. u can either use the larger gtr backplate or the stock stagea one, i had to modify the xmember a fraction (about 2-3mm) to allow the gtr backplate to fit on without touching the xmember.

ask away if u need any questions answered as i did the conversion about 14 months ago.

to answer your question, yes the ratios are interchangable.

I have just picked up a complete S15 diff. I want to fit just the centre in my housing and retain my ratios. Would it just be a matter of disassembling both units, swapping crown wheels and slotting it into my housing and using the stub axles from the s15 diff? I'm assuming I may need to mix and match the spacer washers to get the crownwheel alignment correct? Possibly trying the ones currently fitted to my diff at the moment and going from there. I will try and take plenty of photos and create a thread for my experience once I get around to it.

Did you get a helical or viscous LSD? A viscous, especially an old one, would seem a waste of energy! Also some S15 diffs are 4.083 same as the Stagea (although there are a couple of other S15 ratios too).

I got a helical one. Pretty sure the ratio is 3.69 but I'll double check. Wanted a good street lsd. The kazz 2 way I had in my 180sx was far too agressive for daily duties

Yep if its a 3.69 it should be a helical. Should be a good open road cruiser. You won't find a front one to match - have you decided to stay 2wd (removed the front driveshaft)?

      help to make a 9.5 ratio on a 3.2 rb30/26 block stock

      Which is a thing done by no-one ever. Not even remotely a good idea. I would run an engine with 10:1 these days. Good management and fuel compared to the early 90s when these boat motors were designed & built.

      r34 GTT Excessive fuel consumption on stock Rb25det neo

      I think you misunderstand. This was Greg driving from Melb to Syd (or return) at a constant 100km/h on the highway. Very little throttle movement, very little accel/decel. You should be able to get 8.5 l/100km under those circumstances (which is effectively what he reports - 50L for 600km is 8.3 l/100km). I drive my car to & from work every day, in traffic, on a mixture of 50, 60, 90 km/h roads (and therefore at up to 110km/h!!) with traffic lights and freeway sections. 28 km each way, so about a 30-40 minute drive depending on day, direction and traffic (which is enough for the majority of the drive to be "fully warmed up". I typically get flat 10 l/100km every single week. OK, maybe 10-10.5, every single tank of fuel. RB25DET Neo. It is easy to get acceptable economy. I won't say "good" economy, because modern cars are doing 5-6 l/100km in the same conditions.

      Stagea Suspension

      By GTSBoy · Posted

      Superpro are fine. There are some applications (R32 FUCAs for example) where they are no damn good, but typically for any normal suspension bush, they are fine. Some people will complain of them making noise. Some people will complain of them collapsing. But many of those can probably be traced back to not properly lubing at install or other installation problems, or possibly other problems elsewhere in the suspension that put additional load into particular bush. And for the legit complaints? Meh. Deal with it. I had to replace the poly bushes in my R32 FUCAs every year. The real issue is that I am sold on the idea of adjustability of at least upper arms. So I only have spots for poly bushes in lower arms these days, as everything else is either hardened rubber or spherical steel.

      Suspension really is complicated.... All these considerations are making me over think it all. Again. I reckon I'll wait for SK's response on his coilovers, and go from there. Though if I go MCA, I'll have to decide on whether the extra $600 (voston comforts $1890, mca pro comfort is $2490) is worth it. Just something soft and comfy, yet firm enough when required at the track or a casual old pac drive for a pie... Otherwise, anyone have experience with SuperPro bushings? Needing to replace the bushings on the suspension department... Will probably keep the oem uppercontrol arms etc, and just replace the bushings.

      yes you are right, indeed it is for information only.  there is not much difference being at 9 or 9.5 or 10.  but when I see that you have to plane the block by 2mm if you have taken (example) CP piston which means that you end up with an 8.2 with the rb26 cylinder head.  hence the question I ask is what would be best to achieve what he is asking me.  take pistons in 9.0 or 10.0 to avoid planing a famous 2mm on the block knowing that I worked on the dome of the cylinder head which became total hemispherical
