the definitive GTR transmission thread.

[Dragon Humper]

Mine is still holding up. Will need to upgrade soon though if I want to drive it like I need to to go low 10s. Me thinks PPG or PAR is going to be the only way to go. At least I can use the trans and clutch I have now and not need to convert to a pull type.

anybody experiment with cryo treating or similar?

PPG is nice. They have kits that are around $8000 so it's pretty cheap compared to others.

Gear----Normal----OSG--- OSG+gts-4 diffs

4-----------234------234----------220
5-----------312------284----------267


Also, an AWD rb specific Quaife sequential is "only" 11,000 right now because of the low UK pound. Once my OSG 1-5 explodes, this will be my next tranny

shiet mang, what do you do for a living? That's a lot of cash to be throwing around when you talk about switching from one beefy box to another. Is that 11k US+ install?

Yikes........who quoted you that. I talked to PAR on the phone for about an hour and a full 5 spd kit (dog/straight cut) with billet forks, input and a brg kit was only $5200 AUS dollars. Once their money drops back down to the .90ish range to the Canuck Buck you are looking at only $5300 including shipping, taxes and duty.

HOWEVER, $11000 CDN for the Quaife tranny sounds interesting, I'll have to do some research to see how much power they can handle. If that is what they used in the Jun Super Lemon (the new Brit owner) to upgrade the OSG geared R33 tranny that was in it when it showed up in the UK then it should be good for 1000hp.

I'll do some poking around, if someone has a link to the Quaife, pls share. Found the site, looking for user feedback.

On that page there is a Quaife diff for the front of the R33 and the R34 but no R32, is there a difference?

Anybody try the 98.5+ fairlady gears? Apparently stronger and popular with the 300zx crowd.

[NismoS-tune]

PAR is not PPG lol PPG is better according to many AUS guys and most who crushed their cheaper PAR boxes to move onto PPG or quaife. Now, don't forget, Helical is CHEAPER than Dog gears and that does not include the billet input shaft, no billet selector forks or labor to install the parts into your gearbox which you'll need. If you want to know prices for other parts needed (bearings and what not) and install, you'll quickly realize that 6600AUD is far from the right price. Here's what I got from PPG directly, months ago when I started shopping and crunching numbers (cause I'm one cheap and finance aware mofo):

Hi Franc


Thanks for your email.

If you have a look on our youtube channel PPGEARBOX ,you will see a video of the managing director of PPG driving a 1-4 helical dog set in the shop GTR on the street. It is a common misconception that the dog sets cannot be driven on the street. It is different to standard, but something that once got the hang of is in essence, very easy. I have attached a brief word doc on driving the dog set. Main thing to remember is gear changes need to be quick and decisive.

The helical cut will also give you the quiet street operation, unlike the straight cut gears that make the definite “whine” whilst driving.

In terms of pricing then the GTR 1-4 helical dog set will retail for $6600 AUD + shipping

We don’t actually provide the gearbox casing, only the internals which need to be installed at your end.

Cheers, let me know if you have any further questions.

Used trannys are less than $500 and you could go through about 8 of them before reaching the cost of aftermarket gear sets. I guess if you don't like swapping transmissions on a regular basis though...

I don't like swapping out transmissions, no. 10 days of overtime goes a long way if I change the tranny 1 last time

[Dragon Humper]

I've read alot of feedback on the UK Skyline site that they are feed up with the PPG gearsets too and are going to the OS-88 box, Hollanger or the Quaife (not much feedback yet on the Quaife except for 1 guy who has one in a 500hp car).

I did an online virtual tour of the PAR man. facility while I was on the phone with them, they aint fvcking around, it's huge and they have about $5mil. worth of equipment, all less than 3 years old.


Really it comes down to money, I know that the PAR stuff is much better than stock and more affordable. I haven't blown up my stock box yet after 2 summers of abuse so I know the PAR gears will do me just fine. If I want to go crazy and spend close to $10,000 I'll just go for broke and get the Quaife box or the OS-88 box for $14,500USD (including clutch) from these guys......

or them....

Vex Performance (sound familiar.....LOL).


The UK guys are raving about the OS-88 box and it's half the price of the Hollanger, parts are easier to get too.

hi guys, just thought i would add an option, i had my late 33gtr box stripped, then a giken centre plate fitted and all the gears, input shaft and layshaft cryo treated.. car produces 640 @ the hubs and 580lbs @ the hubs from an rb330 with a gt4094r on the side. done 4000 miles in it now now issues, even done the nurburgring. i suspect an 7k launch would break it, but hey that would break anything.lol

[GT-RJules]

what about this liberty viper tranny for 5k? whats the gearing like? and the weight over stock?

[hozer]

PAR seems to have the best prices for the set... what kind of cost is incurred in having someone assemble those pieces? Also have a bone stock tranny with 550whp and regular track days with almost no issue
