Ok...

Change of direction here...

I might be able to get my mits on a Getrag gearbox, now there are a few questions I need to ask..

1: Would the gearbox fit right into a GT-T from the GTR?

2: How would I go about removing the 4WD transfer case?

3: Is it possible to fit a GTR rear diff to a GT-T rear cradle?

On that note, how could I go about buying or importing a GTR rear diff...

Thanks!

I can't give definite answers, but what i can say is if the getrag fits, after the transfer case if off, it'll need lots of custom work. Think clearances for the transmission tunnel, mounts, input shaft etc. You'll likely need a custom tailshaft. Are GTT LSD's the same as GTR's? That'll come into play if you're looking at a diff conversion. It'll be easier if you use the GTT diff housing and replace the internals with GTR gears, assuming they're different.

I think most of the experts log off when it's prime time :P

It could be done but the floor needs a LOT to work to fit the added box and cut down transfer. i do ALOT of cut down R32 and R33 GTR boxes for S13 and R32 conversions.

The cost of a R34 GTR box and transfer will set you back the same as a Quaife 6sp or similar in good second hand condition..... and they will bolt straight in without all the hassles.

Hmmmm, speaking from your extensive experience, how would a Supra Getrag go?? Obviously it would be minus a transfer case, as the Supra is RWD.. I'm assuming this would make it somewhat easier.. Have you ever done, or heard of a Supra 6spd being installed into a Skyline?? Otherwise, what would the availability of Quaife 2nd hand 6spd's be like? and cost?? Or lastly, would it be possible to fit one of those 6spd manuals from the late model Falcons??? I hear they go pretty well.. However, how would it go fitting into the Skyline's transmission tunnel..

Appreciate the help anyways!

Thanks mate,

Mark.

supra 6 spd or v35 6spd would be preferable and easier

however they question would be why you would do this . given the r32/33 gtr - 33/34 gtst gearbox is pretty strong , good for 350kw at the wheels quite easily your extremely unlikely to push the limits of that box in r34 gtt . so why go for the extra hassle ?

much more sensible idea as you already have the manual box is to purchase an a/m gear set cost 3-4k and put that in , would probably be stronger than stock getrag and no size , tunnel , transfer , custom issues to worry about

Well speaking of the gearsets, are they available in six speed?? Can I get them in Aus? If not, who can import them??

Also, in the event I did want to go to a Supra or V35 Getrag, surely it wouldn't be impossible to pick up one of these transmissions, would I need to look towards Japan? or would there be enough of them in Aus??

Well I've now committed to a 3.6 final drive for my GTT, I'm now back in the ballpark to consider my 6 speed options, I saw a supra getrag that went up for sale just a few weeks ago. That is now sold so it is a matter of just seeing what's around, either a supra getrag or 6 speed gearsets is what I'm looking for...

Any suggestions??

Internally the same. Too much f**king around for little benefit. It's not even that strong a box anyway. I've seen people convert R32 GTR boxes to RWD so I don't see why it couldn't be done with an R34 one. Good luck. Start saving.

SAY WHAT!?

Sorry to bring up an old thread, but what Gearbox did you end up using in the end?

Cheers,

Glen

      He could just take the Bogan Cruise Ships setup... Already got a good setup, with blower, the auto was rebuilt too wasn't it? Perfect time for him to upgrade the tailshaft, diff, and axles...    And wouldn't need to waste money on redoing the Commos seats, as he could just buy race seats for the 5...   As a highly modded car he could avoid the ability to give it away to offspring too when they crash their cars...

      It's really interesting how much it's moving left to right, and doesn't appear to be actually spreading. For this to be moving left to right, without flaring, means unequal forces being applied until equilibrium hits in one way or another.   Reasons it could be unequal; Piston sizes left to right are different sizes. Only minute differences. Pistons moving on different planes. That is, are they moving directly straight at each other, or slightly out of alignment. The fluid is restricted getting to one side.   Some tests you could do. Pull the bleeders on the left and right, fit each side with pressure gauges. It will allow you to make sure pressure is equal (and really, it should be as fluid flow is so damn low, so fluid flow dynamics shouldn't come into it).   With the calipers off the car, have both sides retracted as far as possible, measure very very accurately (think micrometre) distances between opposing pistons in four different spots per set of pistons. Firstly, on each opposing pistons pair, the measures on for different spots should be equal. If it's not, and especially if one spot appears to actually get closer compared to another, the pistons aren't aligned, and now the forces left to right won't be equal, as they're the forces fighting each other.   You can also pull all the pistons out, and very very accurately measure the diameter of them. If they're not equal left to ight in the pairings, and especially if the area of the pistons on one side is different to the area on the other overall, it'll all be out of whack.   My bet, is shit QC in making sure the pistons move in the same plane left vs right. Some minor out of square machining, and nothing will line up, things will want to move around.

      Whilst putting a V8 in a MX5 would be fun, it would negate the whole cheap to run fun daily that the MX5 will be used for If I wanted a faster little convertible I would have got a engine check light, I mean a BMW Z4 M, but going off the issues that the guy at work who recently got one is having, it is lucky I didn't  Meh, horses for courses, the Bogan Cruise Ship is my go to for some horse torques
