RB gearbox options

[Butters]

If your HP goal is reasonable and you are not drifting. Buy a new R34 box. 

If the above is not true, buy a wrecked R33 box and put a gearset in it. 

CD09 are not as strong as you think and the cost of / mess around of the conversion puts you in gearset territory. 

 

Also the deal above is awesome,, get that

What makes you say CD009 boxes are not as strong as you would think? I've always been told the last revision (CD00A) is good for 1000whp and I have no issue's believing it when comparing one side by side with an RB25 box. Makes them look tiny.

Reason I say this is I have seen broken ones, in drift, drag and even behind a stock Z. I do appreciate most of the time its the synchro's that go.   Trouble with quoting HP is it doesn't really say how strong the box is.  I've not seen many CD00X box's make it past a mid 9(150mph) I have seen about a stock R33 RB25 box's run a 9 too, they all go boom at some point though.  

Another clue is they make gearsets for CD00X box's too, wouldn't be a market if they didn't break or have a limit people are going past.  

I totally agree it is a strong box, just have to weigh up the true total cost of the conversion vs rebuilding with a good gearset.

The older revisions did have Synchro issues. It was resolved by Nissan, but I do agree with you on the weighing in the costs and gearset point. Like anything, people will always find a way to break things!
