The OSG sequential is meant to be the strongest of the bunch rated at 1500hp, but its a relatively "new" product so theres not many good/bad stories about it yet. The hollinger is a nice box, but a few rumors I hear of having a very low service life and they can and do break on high hp cars. Hollinger also do not make a H pattern box anymore, only sequential.

A friend of mine is running an OSG sequential and it was chosen over all the above mentioned boxes, as it "looked" the strongest and was rated for the highest hp out of all of them (and the workshop that built the car have seen some Hollinger failures and reccomended the OSG... very big workship in Sydney btw :)). The car is very fresh, ill see if he can post in here once he gets some good use out of it.

Why dont you tell us what hp you are running, then im sure some people can make some better suggestions. Youve already said the Hollinger is out of your price bracket (20,000 plus), and buy the time you grab a brand new Trust H pattern with the uprated input shafts and postage etc, youre going to be coming damn close to the price of the OSG box from Otomoto. If youre running 650hp and under, id suggest talk to PPG (Pfitzner) and get one of their dog sets and uprated shafts.

Ok, stupid question 101:  does the OS G gearset simply fit in the existing GT-R gearbox case?

Cheers,

Lucien.

Basically...

But why are these gearboxes braking? Just because you can do clutchless gear changes doenst mean you can do flat changes without an ECu momentarily cuting ignition?????

Does it come down to a certain extent that ppl dont shift correctly...which brings me to the question. :D

Does anyone actually have any 1st hand experience with these boxes and how you are meant to shift with them?

Gentlemen,

i will be running around 850 hp at crank. RB30 bottom end and 26 head with extensive mods to both, Innovative turbo etc etc..

The chap with Purple 32 and a dog box for sale has already contacted me and we are still talking.

Mashrock i contacted you 3 weeks ago about your box but you replied that it was not for sale at the time.

Now you guys will all hate me for this but i am staryting to lean towards some engineering fabriction time and putting a bullet proof tricked up 2 speed behind it and maintain the 4wd aspect.

It appears that it costs alot for gearbox's that still BREAK, i only want for strip not track.

If you still talking to me , any one with experience here?

I saw Mick featured in ZOOM mag with a two speed, any one know how i can get hold of him for advice.

Still not sure exactly what direction to go in. Simply looking for bullet proof performance.

I know this box isn't in the same league but has anyone seen a 6 speed getrag break as was talk to the tuner of markr34gtr cars and his opinion was they were a pretty good box there not running it now in the 9sec drag car but they used and abused it for sometime with no problems. It just i'm considering going this way as my requirement arn't at suggest a high hp level and it seems the getrag is strong than the std 5 speed.

ps anyone wants to unload a getrag let me know cheers

pnblight:  You mean the one that's in the R34 GT-R?  I fairly sure Troy (ylwgtr2) managed to mangle his.

Lucien.

yes i believe they ran the r34 pretty hard for awhile then got to a point where they transferred the motor to the r32 as they didnt want to cut a r34 gtr vspec to go drag racing. And do you know what broke in the getrag etc and at what hp level he was running.

cheers

I can't find the post anywhere, but I distinctly remember a post by Troy with pictures of the busted gears. Maybe PM him.

I have used the ppg dog box in my car for about the last 18 mounths and have had no problems at all.This box has been abused(me learning to drive it and drag raced) as well as a lot of street driving.I lent this box to a friend for a while and they ran a 10.6 second pass in it as well.I run 600rwhp and my friend ran 700rwhp he now also has brought a box and runs 799rwhp,neither of us has broken one or had any problems these boxes are great ,easy to drive on the street the only down side is they are a little loud.Parts are in stock here in Australia and they are very helpfull.Iwould recommend this box to anybody.Hope this helps.

the v161 getrag that the supra and the R34 GTR use is a steaming pile of poo...... 3rd gear especially.....there noisy and notchy...there fine when you get them into gear....but its getting them into gear thats the drama....they like to strip the synchro meshing teeth off the gears....nissan dont sell parts to rebuild these gearbox's but fortunatly toyoya do....ask snowman....he has broken his...twice

The 5 speed getrag in the 32/33 gtr is stronger than the 6 speed in the 34gtr. The best of the bunch is the 33 series 3 due to the larger syncros & hubs. If you're running a 34 its not just a case of throwing in the 32/33 box as the diff ratios are different.

I've heard of a few trust dog boxes destroyed at around 500rwkw but not OS Giken gear sets at this power level, bonus is they are still a heli cut gear set so street driving is more pleasurable.

PPG are rubbish

What is this comment based on? Anything to explain why you said this as i am sure everyone is curious why you are claiming them to be rubbish, i sure am.

I don't know anything about these gearboxes so i am just interested to find out like most other people here.

Also, about the ikeya shifters, i read in hpi i think that they are slower shifting and more awkard then the stock shifter, great idea but just seems they didn't get it 100% right.

Oh and not that it really means anything but I WIN is running a Pfitzner gearbox in his 33 GTR now, might be worth asking him how its handling the power. If you want to pm him his username on here is MR33.

    • How's everyone going? Just a shout-out introducing myself. I'm James, I live on the north side of Brisbane. I bought an R33 that had been left to rot in someone's front yard for 14 years. Apparently, it has immobiliser/fuel issues. Long story short, it's suffering from a seized engine, plus whatever else turns up once it runs. The car is pretty good considering it sat for so long. It pretty much died after being imported. It has a bunch of Jap parts and a full Top Secret body kit. It's painted Fiat Turchese Festival, or aqua blue if you're not French. Another project to throw money at!
    • So the clockspring is responsible for the indicators cancelling on their own? I thought that was the function of that white thing in the center (any idea what it's called?)
    • Can you log IAT? Whilst WTA coolers have their place, doing any sort of sustained run is not one of them There are fixes that slow down the heat soak, like ice boxes, which don't last that long, and interchillers, which are fairly expensive, up grades to the WTA cooling radiator, which may require a bigger pump, and upgrades to the reservoir size,  and upgrades to the cooling fans, but, it all still heat soaks, and takes ages to come down in hot weather  For a turbo, that isn't locked into WTA like my PD blower is, can you not possibly swap to a nice air to air intercooler????, it would be better for sustained runs then, and have alot less things that could go wrong in my opinion 
    • So, the other thing I've sorted is a baseline dyno run up at Unigroup's new location. The auto trans was a little unco-operative by both shifting down when the throttle was floored on the dyno (so Mark had to ramp it up more slowly than in a manual) and also by shifting up at 6,000 even in sports mode instead of the indicated redline of 7,000 Still, on a hot day it made 240rwkw at 16psi which seems about right for 300kw (400hp) through an auto at the wheels.  The shape of the curve is not quite right because it was not full throttle to about 4,500 to stop it kicking down, but until I can get a tune on the auto trans control this was the best we could do.....full boost will be well below 5,000 once that is sorted, I'll get some data logs when I can to confirm For comparison, the R32 made 255 at 12psi (at 4,500) on the same dyno with tune, n1 turbos, cam gears, big exhaust but otherwise all standard so the v37 is likely a little better out of the box. One thing that is very clear is that the standard water to air intercoolers are not up to sustained use at full throttle in warm ambient temps. After about 5 runs (so only a few minutes full throttle), it was pulling boost and timing and dropping 10-15% power. Unfortunately I didn't get that printout and the Unigroup guys are away at the moment, will try and get hold of it on their return. So, looks like a healthy engine to start modifying and the only real area of concern is the w2a heat exchangers which the aftermarket has plenty of solutions for    
    • I maintain it actually looked really nice in person. So much so that I thought "No, this is illegal" but there it was, clear as day. I think we can easily call the wing and wheels/height to be transformative. Not saying it's better than the GR Whatever, or the 86, or the WRX STI or anything of that sort (the internet says it all bolts up so you can buy best of all worlds?) but it's still at least a thing and not nearly AS bad as people say.
