Hey guys and girls

I have been looking into fitting a T56 6 speed manual gearbox or TR606 to my R33 GTR

I have carried out allot of research I have found out RWD conversions are possible and have been done but no one has done a AWD conversion that I have been able to find.

I think this could be a viable and cost effective option for people who are looking for a quiet street able gearbox which is capable of handling high HP.

Now the cost for a setup like this could range from $6000 to $8000 that is a estimate at this stage the first unit would more than likely be more expensive but with more interest these costs could fall

The T56 Magnum would probably be the gearbox of choice as it is the strongest syco box they do

Able to withstand a massive 700 lb-ft. of torque while providing unbelievably crisp shifts, no other manual transmission on the planet offers as much combined strength, versatility, and general ease-of-use as the T-56 Magnum.

Known in its original equipment form as the 'TR-6060', the Magnum is an aftermarket version of the same transmission found in many of today's most celebrated factory super cars – including the ZR1 Corvette and ACR Viper – giving you refinement where you want it and strength where it counts.

Other positives about these gearboxes are gear sets PPG have dog configurations and sequential setups for the more hardcore drivers. I personally wouldn’t see the point all you would do is fit a PPG setup to the factory 5 speed. The bell housing is also allot larger this may offer GTR owners more clutch options more surface area and the possibility to run a nicer street able clutch (sprung centre)

The biggest positive is retaining the 4WD and for me that the game changer.

This isn't set in stone as yet, I am looking for advice and wisdom there is a huge amount of knowledge on this forum and would love to hear your thoughts and comments

thanks for your time

I've got a magnum in my taxi, got it from mal wood auto in qld with their shift kit and it shifts very well and very quick if you push. Would definitely recommend it.

Problems

- need custom output shaft to match gtr transfer case
- need adapter plate made for transfer case
- before all that you need to find out if the front driveshaft is going to fit without rotating the gearbox
- the cost of paying someone to do this work
- will break anyway and you could have bought a hollinger for the same price

Thanks for the input guy's

Would someone be able to give me some information on the getrag gearboxes?
What sort of power and torque are they rated to?
What type of synco cone setup do they have in them?
Are they single double or triple synco setups?
Are they brass, silicone or other material?

The issue with OS88, Albins or Hollinger is the high level of maintenance associated with them the OS88 is recommended to be pulled down at least once a year
Unsure about the others however I remember seeing similar times for the Holinger
I don’t know anyone who is daily driving a Holinger or OS88. I mean over 15,000km a year

Cost is not a issue at this stage anything I would want to do to the stock 5 speed would be $10,000+ anyway
How do you know it will break? There is a T56 Tranzilla gearbox capable of 1000ft of torque http://www.rsgear.com/products/transmissions/tranzilla.aspx cost is around $5500

What power/torque level do you have or are aiming for?

It is hard to estimate torque
I would like to aim for 600-650hp with the -5 turbos then from there Precision 6466 on a 6boost aiming around 700+hp
My background is Fords 4.0l barra engines. I wouldnt mind having 2x 700whp cars in my garage. One small cube high reving 6 cylinder one big cube 6 cylinder boat anchor hahahaha

getrag is holding up well with 740whp in my GTR

also is incredibly fun response wise due to the close ratios and 4.11 gears
only down side is it maxed out at 268 at racewars on account of gearing if you are chasing a racewars warrior you might consider 3.5 or 3.7 diff gearing

the Motive GTR has a 6 speed getrag in it also with dash 5's is a youtube video of him ripping his cock over how great it is.
