Quaife or Nismo front, same again in the rear and extra few friction plates in the transfer case, commonly known as "the transfer case mod".

Prob looking at $1800 ish to do the front, around the same for the rear and $600 for the transfer.

^parts prices only, right? The quaife front LSD goes for around $1850 without install or bearings or seals.

The setup Piggaz has suggested would give a great setup for OPs application though.

Was also thinking a billet centre plate in the gearbox is not a bad idea. This would prevent shock loading and shaft separation in the gearbox on hard launches at Collingrove. I see you're in Adelaide - feel free to contact us if you'd like any further info.

Centre plate is for the gearbox. No need to change the other gearbox internals if they're working and you're not making spastic power. If eother of those are not the case, then you have a bazillion different upgrade options out there, ranging from $100 for different oil to $20k for a special special box.

What's OPs application?

OP's purpose is "Hillclimbs mainly and the occasional time attack ", OP.

I'd also leave the box until you need to change it, and when you do get a dog box in there for the quicker shifts :)

Jimmy anyone can modify the transfer case, it involves adding the correct number of additional clutch plates to preload it. Award did mine.

The stock centre plate of the RB25/6 gearbox can flex in high torque, high grip situations such as aggressive launches or high speed cornering. When it flexes the shafts (mainshaft and countershaft) come out of alignment and the gears destroy each other. The billet centre plate improves case rigidity. It's basically a full rebuild to install, so would be done with a bearing and seal refresh as a minimum, check synchros etc.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
