Gearbox Re-conditioners ?

[Dohmar]

Yeah thats a good idea Dohmar, But Oosh im not sure what you meant by your comment.

He's referring to the gearbox gear ratios. The OS Giken kit has a different ratio. I'm not sure whether it revs out easier or not, but I'm suspecting its for drag racers? The OS Giken stuff is one of a couple of rebuild kits. Either that or you buy a brand new OEM box for $3200... or find the bits and pieces you need as components and assemble it as new...

-D

[Shadex]

Id rather just by a complete box -_- The OEM ones come built? But are they any good? O_O

[Oosh]

It's a taller gear, it'd be like taking off from the lights half way between 1st and 2nd gear, more clutch slipping so not good in stop start driving but a more usable gear in low-speed corner on the race track where a road 1st would be way too low.

Shadex you still haven't mentioned what you intend to do with this car, is it a tough streeter, dedicated drag or track weapon?

As good as brand new. In fact, I believe they sell the Series 3 R33 box for that same price;

Check that shizzl out... Genuine Nissan Gearbox - Nissan Skyline BCNR33 Genuine Nissan Replacement Gearbox - Nissan Skyline R33 GTR (Series 3)

$3200

Which will be fine for a certain range... I think if ur gonna do over 500hp then you *might* be looking for a rebuild kit (I really dont know jack about power levels for boxes or rebuilds, perhaps someone out there does and can let us know when the time would be to consider a rebuild, cause I'd be interested).

I know I'm aiming for 400hp or so and the GTR box will easily cope with that, so I'm not gonna bother with a hardcore rebuild. Maybe if I get a 2nd job pimping and have a spare $100k to lash out on rebuilding a '32 racecar for targa tassie >

ahh well i can dream, cant i?

-D

[Shadex]

Yea dreamings good lol, But yeah i have seen the brand new box before, i thought you meant a after market stronger box lol.

Oosh, eventually i would like around the 350+ rwkw range, But saying that im not going to go out and do that by the end of the year. But in the next few years i would like to have built a mean street car. Thats the plan anyhow.

thats under 500hp, and I know plenty of people who are running that sort of power with stock boxes and theyre not having any problems. If you can get yourself a good 2nd hand GTR box then you'll be laughing. No rebuilt boxes are necessary for that sort of power provided you're not going to abuse it, or race hard..

If you can afford the 33 GTR series 3 box then get that and fit it. Otherwise look out for a good 2nd hand one of those

Not sure what you men by that. Do you mean Rebuild box's wont take being raced / abused but GTR ones will? Is that what your getting at?

No.

A rebuilt GTR box will have more strength and better ratios for racing or dragging, depending on how you build it. (As in, if you replace the gear sets and put in stronger bearings/synchros) But if you're going to have a maximum of 500 horsepower then I personally don't think it would be necessary to rebuild a GTR box (for street use), as a stock GTR box will suffice. If you get a GTS4 or GTS-T box I don't know what sort of power levels they can cope with by default. This is why oosh wants to know what exactly you're going to use it for. A gearbox for the street is not the same as a dragging box or a racing box, or a drifting box. Different boxes for different jobs.

I see. Well manly it will be just a street box. But what im getting at is i want it to be out to cope with abit of pressure/stress.

Thats a hard one. A std GTR box is tough to begin with, but no box is indestructible. It all depends on how you drive it, what sorta power yr engine puts out, whether or not the clutch is going to help or hinder the drivetrain. For my 2c, I'd just get a 2nd hand GTR box in good condition. If it dies, get your old one reconditioned. Sadly, gearboxes are labour intensive and so will never be cheap to get done, but rather $2000 than a $7000 box if you're never going to need that much...

Not if you brake something

Also see Japese import spares, as they got me a brand new 350z box for about 2/3's the price of the one from nissan and a lot quicker to.

in saying that.

i wonder who makes the 350z gearbox's :S

[Shadex]

Yea but just cause somethings new doesn't mean that its going to stay strong lol, Id rather spend the extra and have something that im not going to have to replace a year so down the track.

I've gotten 18 years out of my current box. Its the same one that came with the car when it was released. Only now do I have to replace it, and even then I'm just taking the cheapest option instead of replacing the synchros. Seriously, unless you're going to go over 500hp, stick with the stock box. Nothing, even a $7000 rebuilt box, is indestructible.

-D

[Oosh]

Stick with stock, but just don't put a stoopid hard clutch in and your gearbox will thank you, think of your clutch like a "fuse".

Remember it's far cheaper and easier to replace a burnt-out clutch than a lunched gearbox.

great analogy

[Madaz]

1. its Getrag

2. i'm led to believe there is no difference between RB25 gearbox and R33 GTR gearbox

lol. you're lead wrong imho. 33 gtr gearbox is an upgraded 32 gtr gbox, meaning it has the same xfer case but stronger input shaftand if its an s3 33 gtr box it'll have tougher synchros. the 25 box is tough but lacks an xfer case (and possibly other stuff, unless theres a rb25 4wd variant? aside from stagea, and even then I doubt they'd be the same as the GTS-4 has different ratios to the GTR so I see no reason why other boxes would be stronger...)...

Caveat - I know sfa about boxes. I could be wrong

-D

[mid life crisis]

Am I glad I've got a Gehtrag!!!!!!

lol u wont be when you have too lift it out for a clutch change :-)

[Madaz]

well shaun at boost worx told me they were basically the same possibly different ratios for some of the gears i dont know

as for

that statement is clearly wrong as R33 cant pull the fuse due to pre-load on the transfer case

33 gtr gearbox is an upgraded 32 gtr gbox, meaning it has the same xfer case but stronger input shaft and if its an s3 33 gtr box it'll have tougher synchros.

you do realise they bolt on and off

the 25 box is tough but lacks an xfer case
