Neat don't yet make the CWP for the 34 vspec A-LSD. I know this because i was talking to them about it last year. They were looking to source a Vspec diff to get the measurements

33Vspec diff direct swap. No other modifications needed to the 34 rear end. Initially, was hard to source the 33 vspec diff at a reasonable price. I found 1 at JustJap. Otherwise Yahoo auctions, or go through an importer like ImportMonster etc

I now have 4.11's - But, not a straight fit for the 34 Vspec. The 33/32 CW&P does not mesh inside the 34 A-LSD diff housing (different wheel to pinion thickness) In order to retain the A-LSD, i bought a 33 Vspec rear diff. Front is the same across 32/33/34.

Pretty self explanatory. Looking for an R33 GTR speedo sensor. Can't buy them new anymore. DM me if you have 1. Thanks

I've been told that the R33 GTR speedo sensor will fit into the Getrag, but you just need to modify the adaptor plug to suit the 34. But in saying this, i've also been told the speedo is still out by 3-5%

Noted and taken on board!

Yep, ok got it now! Took me a while 😵‍💫

Right, not sure if i explained myself correct. So wire in as below? *edit, use accessory power to turn on the unit, i'll prob use the cigarette lighter etc, not pin 29 (ign)

Thanks @GTSBoy - So pretty much i dont need to wire in the "Speedo Out" wire on the Jaycar unit. I.E : 1. Power 2. Ground 3. Pin 19 on 34 cluster to speed input wire on Jaycar unit 4. Leave Speed out wire disconnected. Or ground?

Hi guys. Still trying to find some info. Having replaced my Getrag 3.54 diff ration to 4.11's, my 34R speedo is out. Am planning to use the Jaycar Speedo corrector kit. https://www.jaycar.com.au/speedo-corrector-module-for-cars/p/AA0376?pos=1&queryId=88be0ef7c2dc84f96cf96bd17b61361f&sort=relevance&searchText=speedo Whilst i understand the speed "input" is pin 19, I need to clarify what pin "30" and "31", that being the speedo output, does to the cluster. Jaycar's instructions are: But the 34 cluster has both 2 pulse and 8 pulse output. Ay ideas?

I recently did the 4.11's in the 6 speed Getrag (34 GTR). I already have a responsive setup using a GTX3576 gen 2. I actually agree with you on some of this. YES, It makes a difference, but it's not some magical thing like Motive make it out to be. I still think it's worthwhile, and im glad i did it, but it's not this crazy WOW moment.

Massive thread bump. Anyone know if the speed signal input/output wire (pins 30 and 31) is the same for a 34 GTR ? Have recently changed to 4.11's in the Getrag.

Pretty sure i've posted my graphs in the past on a thread about GTX3576 VS GTX3076 or something. Note - Hub Dyno. So an approx conversion at say 1000 axle rpm speed x 1:1 gear ratio x 3.54 diff ratio (R34 Getrag) = 3540rpm or there abouts for 21+ psi of boost. In the real world, im not sitting there staring at my boost gauge while driving, but i've had -9's in the past too, and i prefer the single.

I'm in Sydney. Im sure we can try figure something out. I'll more than likely be at this years GTR festival and *may* do Motorkhana.

I was told to go a GTX3576R Gen2 on my 34 - Stock RB26 bottom end but with a refreshed head, baby HKS Cams, flex tune, usual mods. Have a 4 inch dump, 3.5inch exhaust running through 2 massive Reaper engineering mufflers. Very very quiet, until the wastegate and screamer come on song (which i love). I couldn't be happier with the boost threshold, transient response and driveability. My goal was to try and compete with R35's for street duties (R35's are still quicker down low compared to my setup). Cant do much with my tune locked... But datalogging, doing a few pulls in 4th gear, last years winter, E85 and on flat highway loading the car up from 2400 rpm or so. MAP sensor showing 155.8 kPA at 3569rpm -which by google translation is 22.5psi of boost. Pretty responsive if you ask me. Tuner said on the dyno was getting full boost (around 26-27 psi by 3800rpm)
