Quaife QBE62G vs Porsche 996 trans

[Kevin B]

All,
I'm planning a build and wanted to get a little input. Is there a strong reason to choose the Quaife QBE62G verses the Porsche 996 transmission. I'm planning a build mostly for the road and am looking at both options. If I am not making a decision based on price what other factors should I be considering?
Thank you.

How much power and what manufacture, model, and size tires are you going to use?

I'm thinking about a 347. I have not decided on tires but likely they will be oversized.

Parts availability. You can get P parts just about anywhere. If it fits your build profile, it's probably the "practical" alternative.

Thank you. That is very helpful.

If I had to guess then there were about 20-25000 996 Porsche transaxles of all types produced, 996 NA 996 Turbo GT2 GT3 etc. They must have built at least 1-2% as spares. That's 200-500 or so. All the dead cars add to that availability count. My complete guess is there are less than 500-750 Quaife Boxes, and that very well may be grossly over estimated. The other thing is the Porsche parts are available from several aftermarket suppliers as well as Porsche.

1st question? Where can you get them repaired? Then can the Quaife's be repaired in the US ? There are at least 3 or four top tier Porsche transaxle shops here in the US.

Do your homework. Changing GRBX types after the car is done is a very big deal. Ask me how I know.............

One more point in favor of Porsche- as in the case of the G-50, there are many gear sets available.

This is all so helpful. Thank you and Howard. I appreciate the comment about changing the GRBX after finishing the build. That's why I want to plan everything out before I get fully started. I definitely want to have something that I can get repaired easily if ever needed.
