How mcuh power does your car have?

5th is just another gear. obviously you're not going to use it at 20km/hr. you won't use 4th or 3rd either at that speed. that doesn't mean that the box isn't strong.

This is what I do when driving normally:

1st 0km/h

2nd never use below 20

3rd never use below 40

4th never use below 60

5th never use below 80.

It has worked for me. Trying to use these gears at anylower speed just loads the engine right up and i can hear the bearings straining.

My car has 480 rwhp.

I have heard that VL turbo gearboxes (very similar to r33 gearboxes) have weak 5th gears and when they have any sort of power put through them something fails and they become noisy and the shifter vibrates when in 5th.

I was just wondering if anyone could shed any light on this?

nope. all gears are the same strength.

just use it.

The only gear that people have trouble with, and you'd have trouble doing this in any car, including a supra box, is when drag racing, flatshifting and hamfisting the stick into third. This only seems to be a problem on the gtrs though, most likely because of the awd and big power.

Not just GTRs. When power is elevated more often than not first and second gears are subject to some wheelspin.

From third onwards when full traction is available the drivetrain has to deal with the full brunt of the torque being delivered.

In theory the clutch should be the fuse in the driveline and never be rated higher than anything behind it. But in practise most people have no problems putting in clutches rated higher than the driveline they are designed to protect hence gearbox, tailshaft, diff,axle breakages.

From what others have said, it is the hamfisting of third when dragging.

You're trying to shift as mcuh as possible and slam it into third at near wot. Apparently it is this mashing of third that kills it.

Just shifting easily into third then planting it, even with moderate power hasn't really killed any boxes on this forum to my knowledge (rb20 boxes excluded because they're like a twig).

    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
    • After @Kinkstaah debacle, I'd never want to try and get it right 😛
    • The hood lines up with the fenders. The front bar doesn't perfectly line up with the fenders where the wheel arch is. You have to 'squeeze' the front bar 'in' as it wants to naturally flare out and be longer on the sides. There's a few threads where people notice this when they only swap a GTR style bumper and front bar. Unless you have genuine OEM items - you may be better served getting conversion kits. There are GTT bumpers to fit GTR hoods. There are GTR hoods (non genuine) to fit the GTT bracketry. MAY
