No. The "H" in R200H stands for helical. Those are a rare beast.

Standard viscous LSD Skyline diff is R200V. Doesn't matter, because the CW&P set from one type of centre bolt onto others readily enough. Example. I have 4.11 gears from an R33/4 viscous diff bolted onto helical centre from an S15, all stuffed into R32 GTSt housing.

also doing some thinking.... can i just take the 4.11 ring and pinion out of the GTT rear end and fit it to the R34 GT-R rear end??? reason for not wanting to use my r34 GTT rear end is the spider gears are welded and the inner half shafts are 5x1 pattern and wont fit to my 6x1 axles in the R34 GT-R rear end

There are one or two small errors in that diff table. All GTRs (non active diff ones anyway) prior to the R34 were conventional mechanical LSD. I haven't paid enough attention to R34 GTRs to learn whether that helical entry in the Nismo table is accurate or not. I suggest an extensive google search for you to try to find out.

As I said in my above post - CW&P sets can be moved freely between R200 centres. I'm sure that there are likely to be one or two cases where that won't work.

Be aware that if your diff centre is in fact helical then they use different half shafts to the other R200s though. Different length on one side. So no easy swappsies there.

But, and here's the thing......you do not have a GTR rear end anyway, right? It's Stagea. Right? So no discussion about helical or GTR diffness is of any value. Right?

here is the Rear ends i have....

R34 GT-R (3.454)

Stagea (4.083)

R34 GT-T (4.111)

the motor and trans I put in my GT-T are from an R32/33 GT-R. so the front diff is 4.111, and i want to stick with 4.111 due to having the 5 speed trans not the 6 speed.

I got front and rear subframes from a R34 GT-R (this is where i got the R34 GT-R rear end and this is why i need to swap the gear ratio)

I cant directly run the R34 GT-T rear end due to it having 5x1 bolt rear axles

I cant run the Stagea rear end at all due to 3x2 bolt axles, 30 spline shafts instead of 32, and 4.083 ratio. -this rear end is basically useless to me

I cant directly run the R34 GT-R rear end due to the ratio not being what i need. however i like everything else about the rear end, its already in the brembo equipt rear sub frame, most likely has a good LSD in it, has 32 spline axles, the entire assembly is in awesome shape and has good abs/wheel speed sensors

-so i want to run the R34 GT-R rear end housing (its cleaner that the other R200 housings i have)

-I need to run the inner half shafts due to them having the proper 6x1 axle bolt ratio

-I need to run the R34 GT-R "centres" as you say due to them only accepting a 32 spline shaft which is the axles shafts that will be inserted into it

-I am need to run the 4.111 ring and pinion from my GT-T rear end to get the proper gear ratio i am looking for

I am hoping the parts above will join

If you can get the GTT CW & P to fit in the R34 GTR centre you're halfway there. Did you get any axles (half shafts) with the R34 GTR rear end? Axles of the right length may be your next challenge. And making sure all the wheel speed sensors are compatible. Are you trying to replicate the whole Atesssa set up with ECU, central sensor etc or are you copying the English model of just using a stand alone controller (as in another thread here)?

    • Mate you saved be from dying in the Perth summer. AC wasn't changing direction and just going into diagnostics mode fixed it. You're a legend and I would shout you a beer if I could!
    • Unfortunately effort gone to waste, you will have substantial issues with how the manifold and wastegate have been integrated. You would be so much better off with a modified stock manifold like this: https://hypergearturbos.com/product/rb25detexgatedmanifold/   OR literally just getting a off the shelf Sinco or 6Boost manifold as myself and others have mentioned.  
    • Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!
    • Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.
