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)?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
