Manual Swap Options

[taz2069]

just wondering which transmissions are a good swap option?

i have been hearing about using the trans from a 350/370z as well as the 5 speed swap and the getrag swap.

all im looking for is to change from my auto trans to a manual.

what do you guys have for options if they are not listed here?

Do the 350 (make sure not the older one, the new one is CD009) or 370Z swap.

Best box you could do, tell me how you go

No one I personally know has done it, you can be the first haha

If you just want to convert to manual why not just an r34 manual setup?

surely that is the only one (or r33 or r32) that actually just bolts on

those Series 2 350Z boxes, aka CD009 will happily hold 1000hp (or 700hp AU numbers, 30% yanky inflation).

Chris Forsberg's twin turbo 370Z uses the stock box (essentially a CD009).. makes silly power and gets drifted off it's tits.

Cheaper than the likes of OS Giken, PPG, PAR, etc...

The cost of those mentioned gearsets will be a brand new box delivered to your doorstep.

There are a few kits to slap them to SRs however nothing noted down for RBs

The problem with the 5 speed swap is the transmission is getting hard to get a hold of in and around Canada because all the 240's the s14/15 and Silvia guys are converting their cars to the 5 speeds from the r cars because it's a better trans

And I would prefer something in a 6 speed setup as I do lots of highway driving

If it were me looking for highway gearing I'd be putting some 3.7 gears in the diff. Would work well with the 5 speed.

The other thing people are doing to get 5 speeds is getting the (apparently) same gearbox from D22 Navaras and swapping the bellhousing half of their old/worn out RB25 box.

Putting VQ gearboxes behind RBs has been thought through, but like Johnny above, I'm not aware of too many that have been done.

there's this:

but no one I know has used it b4.. in theory seems easy enough, however theory usually always translate to real-world.

Is there 14mm of meat that can be safely taken off the bellhousing without trashing the strength of it?

You are going to have to change diff ratios as well if you want to match or drop the revs you are doing now on the highway. The auto box has a 0.694 4th gear ratio, the 350/370z has a 0.794 6th gear ratio and the RB25det has a 0.752 5th gear ratio.

Cheapest option (if you don't want a second hand gearbox) is buy a brand new 5 speed and change the diff ratios.

Another option is a Tremec T56 and adaptor plate

Just found this

Alpha omega wouldn't machine more than 9mm off the bellhousing.

Toyota have a 6 speed Getrag - maybe someone in the States makes an adapter plate - and get an R34 GTR diff (3.545:1)

Just had a look on TradeMe and used RB25 boxes are $2k - $2500!

Have you checked to see if you can buy them brand new from Japan?

There are a couple of threads on this site with instructions and a parts list for the manual conversion - the centre console may be hard to come by as well.

the toyota 6 speed getrag is just to expensive for just a swap as its around $8000us. for the build i plan on doing down the road it will be perfect,

and by the time i import the used 5 speed box it will be around the 4-5k, im looking for something i can use without costing crazy money until i do my build.
