Hey guys,

Driving home tonight gave it a squirt in first put it into second, full throttle and then when it came onto full boost I hear BANG and the whole car jerks and theirs a massive rattle sound coming from the gearbox,

I quickly pulled over and turned the car off had a look underneath to see if anything was fallen off or anything but coudlnt see anything out of the ordinary, got back in the car started it, MASSIVE rattling sound coming from the gearbox on idle even when the car was in neutral, car very hard to get into gear, took off in first took off very hard just that massive constant rattle, everytime I tried to put it into second I just get a massive bang and the whole car jerks and it wont go in so I managed to baby the car home in 3rd (with that loud rattling noise still going constantly seems to ease up a bit when the clutch it put all the way in and the car is idling)

Ive booked a tow for the morning to get the car to a workshop but does it seem like the gearbox is gone?

Why do these things happen at the worst times was just preparing to put my new turbo on and fix some other things on the car :cheers:

if it's at idle (in neutral), its likely that it's the clutch and not the gearbox

because obviously nothing in the gearbox should be moving in neutral

does it still make the sound if you push the clutch pedal in?

Hmm hopefully thats what it is mate I just replaced the clutch with a heavy duty one 2 months ago though so not sure why it would of caused this.

Yeah it does seem to go away if you put the clutch in and its idling but when I was babying it home whenever I put the clutch in as the car was going along it would still do it but I guess the gearbox would still have things moving if the cars moving right?

Sounds like the g/box is gone, when in neutral the main shaft still turns . The only time it doesn't is when the car is not moving and clutch pedal pushed in.

you learn something new everyday!

thanks for clearing that up :cheers:

to put it plain and simple:

if your car is rolling (clutch in OR out)- there will be a section of the gearbox that is moving.

if the clutch pedal is out, and its in neutral (regardless of rolling or not rolling) there will be a different section of the gearbox thats moving.

to get a very good understanding of how gearboxes work i reccomend this link:

your description to me sounds like your gearbox has been raped.

my condolences for your loss (as much as i like to be right, i hope im wrong). i hate it when bad shit happens to pride and joys.

cheers. james.

EDIT: took me so long to write this up, your question has been answered before i finished! but atleast i supplied a good link! cheers.

Dude if you are upgrading to a bigger turbo I would change to an R33 gearbox as 20 ones are fairly weak. Is a bit more expensive but better in the long run as its 1 less thing to worry about busting all the time.

Shit bad luck dave and you haven't even been able to put my turbo on yet!! :P

Although R33 boxes are stronger, I can't see the need to upgrade to one unless your pulling some decent figures already, and plan to take the car alot further power wise.

FRom what i've been told you need the g/box itself obviously, approx $1500, get it fitted, and i'm pretty sure you also need a custom made tailshaft, and alot of other crap to get it working.. it's a costly exercise, but you would never have to worry about breaking the box again!!

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
