Hallo, I would like to offer Kalmar Motorsport 5 speed dogbox kit with straight cut gears. Our kit is for standart casing of Skyline GTS-T R32,33,34 and GTR R32,33.

We produce this kit with:

- standart input shaft RB25/RB26

- 2JZ input shaft with transmission spacer

- SR20DET input shaft with transmission spacer

You can contact us via FB page: https://www.facebook.com/kalmarmotorsport

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.

Its for Supra 2JZ and Silvia SR20DET aplication 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.

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.

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 👍

    • I would try messing with friction modifier to see if it smooths it out.  Just keep adding more until it stops chattering or grabbing quite so much. If you haven't changed the gear oil in a long time you may as well start there too in case that has anything to do with it. You might want to also verify the initial torque is set to the lowest setting too. Requires popping out one of the CV axles first but that's not too bad. Once you're sure the preload is set to the lowest you can try adding an ounce at a time of friction modifier until it feels right to you.
    • It is possibly 55 degrees for the Nismo version. I had a look through the manual and the stocker has a breakaway torque of 2.5 to 3.5kgm. Supposedly the Nismo LSD goes down to 5kgm when worn in but it is pretty grabby even with very little throttle. Worse when cold. So I guess you have three things. 1. Shims. 2 Friction plates 3. Cams Would think shims would be the easiest but Ive no clue how many tenths of a mm shim thickness change equals how many kgm torque. Also not sure if the Nismo friction plates are similar/different to stock or if they are the most of the source of the diff being angry. Think I can write off the Nismo rebuild kit for the standard diff as not being what I want.  
    • Yeah, it was a bit of confusion with me, I rang and asked if they had a boot for a soft top, and then the paint shop when they rang and were asked if it had a hard top on it, which it does, just not a PRHT....LOL Meh, whilst frustrating for all concerned it isn't a war stopper and should be a thing of the past in a week or two In other N/A related news, car is booked in at the end of the month for the cams, springs, retainers, harmonic balancer and retune  I might even pull the lazy arse card and get them to do a full service on it whilst it is there
    • Factory LSD is supposedly a 2 way with a very conservative cam. If you've already tried adding friction modifier to the diff oil and it still locks up too much for your liking you might want to adjust the ramp rate on the cam to be more like OEM instead of reducing initial torque even further. People claim the 8 kgf-m disc kit for the OEM LSD is still very streetable but I've never been able to compare everything side by side on my own.
    • Oh man, at least it sounds they've accepted they stuffed up and not put it back on you...could see some confusion if they asked if it had a hardtop or not, and you've answered truthfully but maybe not answering their real question which is what roof did it have from the factory! Glad your keeping it N/A 2.5
