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?

      Rb26/30 build

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      Nismo rear spats

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
