Just a standard 33 box in a 26, but I haven't got the torque that you will have, no where near. The torque is what should be considered rather than the power. Just something to investigate anyway. You don't want to be smashing the box first up and have to wait to get one built if it's your dd.

I had better do some homework, thanks

XGTRX , I have looked some more and you are right there is a bang waiting to happen :/

Starting to find out a few things and one of them is change the Quad for something a bit softer and more forgiving on the box.

This is why I joined the site, to get help with things I do not know about or fully understand. It is a learning curve, it is easy not to look ahead at what some changes will make with something else, bloody cars, haha :)

Thanks Pete

Make sure you are looking up the Getrag box and not the Nissan 5 speeder, the 6 speed R34s have the Getrag box

HI Mick ,I understand that and I thought the Getrag was a beefy box but I guess when the type of torque I will have kicks in when driving hard, something will eventually give out.

Paul suggested to dump the quad and look into the Coppermix C Spec.

Looks like I have got myself into something, but all good :yes:

These boxes are pretty strong but no box will take abuse for long with this sort of torque, that said as long as you don't go slamming it throw gears ( especially at high rpm ) and don't drop the clutch for the floor boards it will hold for a while

Edit: and run the right oil, PM me about that :thumbsup:

Really comes down to how you drive it, a bit of machanical sympathy goes a long way

I have a triple plate in mine at the moment and other then the rattle its not that bad but I always load the driveline before giving it the sauce, a good twin plate would be nicer on the box and to drive, what Paully suggested or an Exedy Hi-Torque twin would be good

The Nismo 2-way is the tits, just look into a Quaife ATB LSD for the front

I do not drop it anymore , I did when I first got the car there are blokes on the forums that say build it and step off, but 5 minutes here listening to some blokes that had a brain I stopped that and always load it first.

Not sure if I should see how the box is with the quad clutch or bite the bullet and just go for one that is not as hard on the box.

you won't break a gearbox in daily driving, 400kw or not. they only break when being abused (racing, drag racing, hectic skids etc)

I do not think my driving is a real danger to the driveline. I think with the new set up I am sure I will give it some but not like a boy racer.

But one never knows, I thought my last mods would be enough but it was not , so here I am again talking about a bigger build, got me stuffed??

Yeh , just been kicking back with a red and thinking I might go with the build as is but do the Quaife Diff and see what happens, if something goes pop, fix it. I do not want all of these leftovers sitting around the garage :yucky:

Or pull out the weak links while they are working and get good money for them and get something to cope with your setup. Don't kid yourself you will abuse it once in a while and with all that torque it will go bang. Just search the forums and see that this is the norm.

Oh, I believe there is no doubt that will happen. :yes:

Trying to nail down exactly what I want and then what I need. I will try to do it smart by using all of the info you blokes give me and running it past the builder and I hope for the best outcome :geek:

  • 1 month later...

Hi Mick, those OS88 look like the real thing, wonder what they are like on the street, I guess not too driver friendly but you get used of things after a while and seems like the norm :unsure:

Have all the parts ready to get the build going.

Decided to go with a Nismo Coppermix twin Comp Spec clutch , some of the boys said they are a great clutch and will be a little more forgiving on the box.

Also swapping the front diff with a Quaife ATB Helical.

Just waiting for them to get an RB30 Block and it can get started :yes: Stuffed if I know what is taking so long to get one :unsure:

Hey Pete,

They look pretty easy to drive, I have driven an Albins 5 speed and that would be ok as a daily if you can handle the whine of the straight cut gears, just gotta remember to get into first before you completely stop :D

The OS88 is helical cut so no whine :thumbsup:

The quaife is a good thing, I have one up front of my 34 and you don't know its there till you get up it then it flawlessly in-gauges and pulls you away

There is a dozen RB30s on eBay at any given time and some even come wrapped in a car :D

Taking long enough, this should have been well under way by now :(

Good to see this is still going ahead

So you cannot drop down a gear or 2 if you are not moving? I thought they would be like a bike? At least I will not have to worry about that but I love they way they boot through the gears :woot: Some of the boys there are going for the OS88 and it will be interesting to see how they like them.

I am looking forward to using the Quaife along with the rest of the build.

Never chased second hand parts for a car and to be honest I would not know a good RB30 block from a heap of crap :unsure: I will have a look on Ebay, but maybe I am looking at the wrong thing as I have typed in RB30 block and get nothing?????

It has been 6 weeks since I gave the go ahead for the build, I have everything ready, so I will just hope for the best BUT reading some builds on different Forums I am sure mine will be done and dusted long before some that started 2 or 3 years ago, shit I might be dead if I had to wait that long,haha :woot:

  • 2 weeks later...

With the OS88 6 speed sequential, bear in mind that there is a 2 to 3 month wait on them ex-OS Giken as they only put them together after they have been ordered (and paid for).

I like what you are doing with your 3.2L build. Should be an awesome street car.

There is a guy on here in Perth with the forum username "chavey" who has already completed a similar build to yours in his R32 GTR but uses a GTX3582R turbo. ;)

  • 4 weeks later...

HI Charlie, going to have a look at Chavey's build, thanks

I see Piggaz is just ordering the OS88 box , cannot wait to hear how they go as a DD and Paul's car should be a good test and I believe he likes to drive hard as he keeps braking things, sorry Paul :)

I dropped my car into the workshop on Tuesday and now the wait starts :(

After listening to you blokes I ended up confirming some changes to the driveline and will see how the Box goes or when it goes before I change it.Better start putting the $$$$s away

Gone with the Coppermix C Spec Twin(over 700HP), Nismo slave cylinder, Quaife front diff , modifying the Trannie and already have a Nismo 2-way LSD /back.

The boys said to try the Unigroup 260 10.8 cams as they will give me more air, Better springs and retainers, cleaning the head up, oversized valves. Staying with the PT6262 B Turbo (over 700hP), maybe a larger back housing depending on the results.

Just waiting to see how the Walbro 460lph goes when the tune is being done and work off the results

RB30 Block has been modified. Plus all of the other part to go with the Nitto 3.2 Stroker Kit to make it a strong motor all round.

Going to have to make it stop now, Piggaz suggested I look at the Endless Brakes as they are strong and still work OK cold for a DD.

While they are doing the job I am having the Haltech Flex Fuel Sensor tuned in with the build , just in case, well you never know what you are going to want in the future, I was happy with the way it was, well for a few weeks ,haha

It will be around 400awkw, no big turbo/s or big cams, response and linear power from the start to the limiter, well :/

    • I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.
    • Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too. 
    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!
