Are you blowing gears or making loads of power? Standard GTS-T and GT-T boxes are very strong...

No cheap way about it if you want to uprate, will cost you a few grand for an uprated gearset...plus reconditioning and installation...are you prepared to spend that kind of money?

Give it up fool. Third gear is a common breakage in GTR boxes even in standard vehicles. Pushing 400kw with a heavy duty clutch during motorsport and you expect a non run-in reconditioned gearbox to hold up to that...you're dreaming.

Gearboxes and life expectancy are the length of a piece of string - you could get away with 600kw through a standard gearbox if all you do is drive to the shops and dyno days. Give it some stick and it's another story.

For the record GTS-T and GT-T boxes are known to be stronger than GTR boxes (excluding 6 speed) despite sharing similar internals.

GTR & GTS-T boxes are pretty much the same.

They are not "weaker" as such, it's just the big RPM launch + 4WD = death with the added stress and usually 2nd or 3rd gets stripped.

For a daily driven GTR, that doesn't get treated to nasty launches and driven with some mechanical sympathy there is no reason you can't make 380rwkw and be fine.

That said, you never know the condition/life of the gearbox half the time so inherrantly you might not treat it poorly and it will still give up the ghost anyhow.

Given we are talking a GT-T here, my first post stands.

We are not talking about GTR's of which the answer isn't quite as simple.

Its not so much the power your making but the torque.

Being rwd youll have it easier then awd cars. running semi/full slicks will cause more issues. also if you have a harsh clutch that can play info things as well.

Finally (and what i believe is the biggest factor) if you drive like habbib at the local kabab shop, smashing the gears around. Even with none of the above, dont expect to be lucky.

Stress and bad driving have broken more gearboxes then hp.

i know of 2 broken GTST boxes in all the cars ive known

one was a wierd anomoloy, the other was Rb26 in ER34 RWD

ive been driving mine pretty hard with basic power for 7 years and its fine

no mashed cogs, no blow up box, no broky etc

the stock box in the GTST i reckon is bulletproof

go ask a WRX owner what they think of the std box in the WRX

Sorry Ash the first part of my post was directed at xrotor, can see how you might have taken it directed at you given our quoting of power figures and statistics. Only reason I brought up GTR's is because of xrotor's post.

I've read it is the added stress of the transfer case on the output shaft responsible for the 3rd gear breakage in GTR boxes, but yes hard launches will do it in the lower gears. Rear wheel drive versions of a gearbox will always be stronger than all wheel drive (unless the all wheel drive has larger internals) because of less components and less things to turn. That is what I meant by the GTS-T box being stronger despite being similar.

thanks for the replies guys,

i knw that gear box's are strong i just dont wanna blow mine when am kicking it out here n there.

i got a mate with R34 who loves to kick it every where, now his gear box making all kinda of noises rattling, winding sound like a turbo lol.

i just dont want to have same problem, or is this normal when u thrash the gear box lol

It's normal when you thrash a gearbox for it to start making sounds after a while. Or any part of the car for that matter. There's a negative correlation between thrashing mechanical components and lifespan. Two options: drive it with care or fork out lots of dollars for more strength / replacement gearboxes :P

And yes Paul, WRX box = 2nd gear ripped off the mainshaft 90% of the time. Not cheap to fix them either!

or sounds like he loves to thrash it dumps / kicks the clutch every where lol

No, sounds like he does not know how to drive.

Simple as that.

Sorry mate but I've given my gearbox so much curry over 6 years and it's the same as it was the day i purchased it.

I've done over 100 passes with that gearbox, a good number of them with 370rwkw as well.

So you can imagine how easily my tyres turn on the street. I never miss a gear, clutch is always working 100% perfectly and i never change faster than the gearbox.

You mate does not know how to drive if it's making below 300rwkw and is failing.

This is exactly what im talkin about birds, i had 300kw running low boost and bang! this time im going an OS set through a reputable business who know their shit, unlike some who knows everything about nothing.

Im pissed off with you more so that you charged 2k for a box outright and reco'ed my box that was f**ked!

You may one day do this to the wrong person :P

You have absolutely no idea what you are talking about, you make falsified claims, and that is why both Chasers and I told you where to go. For the record, even if you had standard power and a standard clutch and you came to me with a stripped gear I would still tell you where to go because it is NOT covered by warranty. No gearbox reconditioner, no matter how "reputable" will cover that damage under warranty. This is clearly explained on our invoice. If your mechanic, who purchased it from us, did not explain this to you clearly enough, then your issue is with him. If you have an issue with me, take it up with me outside of these forums using whatever avenues you would like to instead of trying to paint one side of a story here. End of discussion on the matter over these forums.

So the op is looking at 5K for the OS giken upgrade? I assume the alternative (PPG) is a similar price?

Sounds like it would be worth staying stock unless you know that you break standard gearboxes due to extreme power levels, and not poor driving technique :D

I am curious how much a standard + new sychro's rebuild is :banana:

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
