I'm prepping my drivetrain for a goal of 300HP. My car is a 99 with a 5 speed and a 4.3 currently. I'm moving to a 6 speed, and plan on swapping to a 3.3 in the rear.

I found one vendor selling 3.3 sets: MFactory

Any opinions on this vendor/gearset?

Edit: found this thread: https://www.miataturbo.net/suspensio...earsets-92250/ looks like the vendor is the real deal.

 

I have one already installed with a Torsen for sale, send me a PM if interested.

 

Walter-motorsports.com sells them too. I have one in the way.

There is a huge thread on here for M factory one.

 

MFactory Competition Products - Performance Driveline Components

 

I am running the MFactory 3.30 set in my car and it's all good.
