Tuff "dog box" Wanted -where?

[Amaru]

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.

if i find out how much its going to cost you to get my one fixed would you be interested??

PurpleR32 on these forums has a Trust 6 Speed in the car he brought over from Japan he is looking to off-load.

If interested maybe send him a PM.

that OS Giken box looks spookily similar to the 'new' HKS 6 speed sequential box on display at Tokyo Autosalon earlier this year. same power rating too.

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

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.

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.

[R31Nismoid]

use an OS gearset.

If your nice it will last, if u abuse it of course it wont last

2 speeds... bah. thats not racing a GTR.

you aint driving a taxi

[Amaru]

If it were my car, id splash out the money for the OSG sequential (not the gearset)

[pnblight]

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.

pete

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.

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.

[pnblight]

what a ppg box worth and who sells them

cheers

pete

[Amaru]

$8,200 for a 5 spd dog box and $9,000 for a 6 spd dog box with selector forks.

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

[IMACUL8]

go the ppg dog box then use a sequential shifter made by www.ikeya-f.co.jp. U can really take advantage of cluthless gear changes then.

PPG are rubbish

[thechief]

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.

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.
