I take it we wouldn't get charged VAT, so for us Aussies over here around $7600AUD + plus shipping plus import tax / import duty / GST etc. is about $10k AUD before installation. That's a hard sell mate compared to a locally available PAR or PPG H pattern gearset. You'd have to give SAU a pretty good run down of all the technical info ie. Ratio options, gearset material and construction, selector fork material and construction, additional treatment / finishing processes. Get my drift ? Fill us in on the specifics if you will.

In saying that, last time I looked PPG were charging over $15k AUD for their gearset before shipping. Hopefully they will give us more details, I'm interested at least. Blew up my 3rd gtst box last weekend, HMU if you want to discount me a gearbox for testing 😀

Ok no problem.

Our ratios are:

Constant 1,411 24/17

Gears (ratios including constant recalculation):

1. 2,62 26/14t

2. 1,72 22/18t

3. 1,27 18/20t

4. direct 1:1

5. 0,856 17/28t

All our gears and shafts are made from billet steel with carburising and heating process. 

Selector forks are also made from billet steel with tig welded shifting part (pin lock inside just to be safe :) ) with nitriding process on the end.

Constant and 5th gear are specialy machined to be more quiet.

We have now more than 5pcs in stock so no waiting for production.

We are always keeping around 5 pcs of every part of our dogbox kit in stock for fast delivery to customer in case of problem (short time before the race etc).

Is this enough? :)

How does your gearset compare to Speedtek's gearset for $3,650 AUD?

Why would you even bring that up ? Mate, the Speedtek is a wannabe OS giken synchro helical cut gearset , this is a straight cut dog engagement - you can't really compare the two can you ?

@martym10Ok on paper this sounds not bad, thanks for the info ! For comparison the same sort of thing is a tad under $10k from PPG with similar ratios.

$15.5k from PPG gets you installation including the extra billet centre plate and billet main shaft.

From the photos I would be correct in saying that this box is assembled on the standard centre plate using the standard Nissan main shaft, standard 5th/rev selector fork and standard shifting interlock barrel ? Also what's up with the transmission spacer ? Why would you need to do that ?

Just saying, because no one is going to be putting a high $ straight cut dog box gearset onto the extremely weak standard centre plate. Do you have your own solution like a billet centre plate ?

I also strongly suggest you make an input shaft in the 26 spline, 28.5mm configuration as per GM / Chevrolet specification as most clutches for RBs can come with this clutch hub centre spline size option.

Not sure about this gearset, but we offer dog box kit (not synchro) with straight cut gears (not helical gears) with roller bearings on shafts. This setup produce less stress on casing. Larger teeth on the gears can hold much more power.

Yes like is on picture, our dogbox kit uses standart main shaft (which needs little bit of machining modification on one place), standart 5th fork and main shifting rod and finger (if you mean that). We don't produce centre plate, but if someone have bad feeling about that, can buy billet centre plate from PPG. I have two these sets on drifting cars. One S14 with 660ps/780nm nad one 350z with 2JZ engine 590ps/800nm. These cars are on standart centre plates.

Its for Supra 2JZ and Silvia SR20DET application with skyline gearbox. In fact, it's not even as much a spacer as an adapter. Another block needs another matching face of bellhousing of gearbox if you understand me.

Gotcha, I thought it might have been an adapter plate but it wasn't made clear with the input shaft options. At first I thought you might have been doing a Toyota JZ 21 spline input shaft for an RB application like Quaife in the UK have. So what I was getting at is most people in the RB circles move to a 28.5mm GM 26 spline input shaft for RB applications, instead of the much weaker 25.4mm Nissan 24 spline input. All Australian performance box manufacturers like Holinger, Albins, PPG, PAR for example have this much preferred option. Its that common the Japanese like HKS, ATS and OS giken actually refer to it as the Holinger spline.

Anyway I'm sure someone will take the plunge very soon. Good luck with the gearset release 👍

    • Far out, people still post here occasionally!
    • I still await Startrack for my Balancer. In the meantime, my lovely girlfriend sold her Turbo MX5. Her criteria was "Something Japanese, Fun, but a hatchback" (cause she doesnt like 100kmh highways in a MX5, and tends to go to bunnings a lot) Basically my Megane, but Japanese. Because she is blessed, not cursed, this is now in the driveway, 1 day later. Bonus Extras (that she and seller didn't notice, but I did) Genuine P1 Buddy Clubs Genuine Mugen Wang Short shifter of some sort (shifts amazingly, def not stock - we test drove a few cars) Aftermarket Helical LSD (Quaife?) One of the other ones we tested had an Intake, for max VTEC sounds. So we're getting one of those. As for how it drives, I have now experienced 3 different cars in this household I should primarily drive around instead of my R34. I googled bolt on supercharger kits for the K20, which was the inspiration for my mate's supercharged BMW, and found that when I overlaid a video of someone doing a 50-250kmh pull, and my own video at Sandown in the LS Skyline... they were identical in acceleration. Every frame of the entire thing. It was eerie. My lovely gf is extremely happy, and I am too. They really do drive excellently, and the fit and finish and interior is just awesome. I am more excited to drive this thing around than my own car, which I hope to high heaven is just because it's new to me and a great deal/hilariously good buy. However this completes our household change from Turbo life to N/A Purity!
    • Yeah, it's a real thing  But isn't that what hobbies are for
    • Yes, a brand new box needs to wear in a little, and the "big box" is actually pretty beefy compared to most. Just treat it nice for 500klm then change the oil, see if it improves
    • Just put in a brand new RB25DET big box, auto conversion. Last time I drove manual was my 260Z, 15 years ago. But this box seems a bit notchy shifting up. Are new gearboxes like this? Do they have a break in period? Also noticed a vibration on the clutch pedal when shifting close to red line. It is R34 box, with a pull clutch. I installed a new Nismo sports clutch with a slightly lighter flywheel. I am running Penrite Pro Gear 75W-90. Cheers
