He said something about being in the bahamas.......and thanks Snowy;)

What was the cost of the parts mate. Just contemplating the possibulities later on (or taking advantage of someone who busts a gearbox and sells it)

They are definitely not the same

neither will the new holden 6 speed.  

Getrag is a brand not a model, remember that.  

as for parts. a 6 speed sequential box from hollinger would only cost you a little more... while a gear set will cost you alot less

The R34 gtr uses a V160/161 getrag transmission.....as does the JZA80 supra(and i assume that this tranny is used by a number of other vehicles) ....therfore the internals are IDENTICAL....there are two types of synchro's some have 6 tooth and some have 7 tooth....you dont know what you got until you pull it apart.....the gears are about 500 each and the synchro ring vary from 70-120 each....the shift drums are 280 each

heres a pic of the new gear.......the arrow point to the teeth that snowie likes to destroy.....these are the dogs....the shift drum locates on these and locks the gear to the shaft when selected(the synchros job is to "synchronise"these 2 componants by acting as a brakepad for the gear(it rides in between these two parts)....these little teeth transfer all the power!Its quite unbeleivable

I am in the automotive trade....lots of my friends have panelshops/mechanical repair shops both here and in japan...i usually get called in for one off jobs,jobs that require attention to detail or jobs that require a bit of engineering/design for componants that have been damaged,failed/have a design fault or are no longer available so therefore have to make the part in question,basically all the ball breaking jobs :cheers:.......sometimes i am asked to fix the unfixable...i usually do something starting with the letter "F" to it and it aint fix :)

I think    The  WHITEs  that came 2 outright in Targa Tas   in there GTR   made  there own syncros ...  you can Not buy all the parts in a BMW Getrag 6 speed as they only list certain parts in the box 4 sale .. other wise a exchange box from Bmw  ..   Getrag rate there boxes  as the Maximum  inputshaft torque in  newton meters  the box can take safely  .. So not all Gearboxs with the Name Getrag are the Same ..

If they made their own synchros and they were ina ny way different to the factory ones, they should be disqualified.

Oh, they were.

on another note.....its not a power rating issue with this particular gearbox....its the fact of getting it into gear in the correct manor thats the problem

hahahaha has snowey been a bit rough with it?

      He obviously had his reason for flipping you off. I wonder what it was...

      I have to agree like, yesterday, I was driving down the warringah freeway towards the bridge when this jackass driving a beaten up Honda civic cut me off so suddenly it made me almost yank the wheel to avoid him hitting my car. Honestly and he had the NERVE to flip me off (or some other gesture Idk). Im a calm guy, but really some people just dont deserve to have a license, let alone be allowed to drive on densely populated roads/highways. If youre gonna cut through lanes at least use the damn turn signal

      Mistakes were made, my R34 Story

      HPA do an interesting video on tuning, and Adrian shows on the dyno, moving from 10:1 to 12:1 (And I think even 13:1) and the power moves SFA. However, a couple of degrees of timing has a HUGE impact. Exhaust side of things will more be the length of the exhaust and how many bends and turns you have. The straighter you can keep it, the better. By a lot. Oh, and getting the diameter right. Bigger isn't always better. Going to big can actually lose you power.

      I have to say, most people I see on the road fit the bill of atrocious drivers. Whether they be cowboys in their dual cabs, bogans in the Commodores, or the soccer mums. Pretty much most people on the road put zero freaking thought into driving. Barely look further up the road then the end of their bonnet, and have never even thought about how catastrophically wrong shit can go, by doing what they all deem as normal driving. Especially their late braking, racing to stopped lights, and sitting half a foot off the bumper of the car in front at 110km/h. Wanna know what's even better? By the time their kids get to be old enough to learn to drive, they've already got in the back of their brain what is normal driving, how annoyed you're allowed to get at people etc, and then their parents who actually have zero freaking skill at driving (Even though they constantly say "I've been driving for 20 years and never had an accident!") teach the little twerps how to drive, or should I say, how to make a car move. Literally watched a parent teach their L Plater, on a 4 lane freeway, that you just slam the brakes on, and push your way over, even with a B Double bearing down on you, and that's how you should drive, rather then, just keep going to the next exit. Same shit happens all the time for side streets etc, watching numpties pull dumb shit turns pushing across 3 lanes of traffic, rather than just go up the road another 30 seconds, and take the next turn that'll get you to the same location... Oh, and the damn right lane bandits. Or the retards driving along with their headphones in, and can't hear the ambulance or fire truck right up their ass about to run them over...   Pretty much, people drive on the road, like ego centric f**ks, and don't actually think how dumb shit their driving is, how it could easily kill them or someone else in a split second, or at the very least, how they're driving is contributing to all the shit they're bitching about on the road, like shitty congestion!
