Subaru EZ30R conversion, will the 6 speed transmission work? Options

[Aircooledfool]

I would like to use the 6 speed transmission that I can purchased mated to the EZ30R. When I look at Bremarauto's site, they say their 2WD conversion kit does not work with the 6 speed. Has anyone already used this transmission? If so, can you point me to the conversion parts you used?

So the Fury model ecu will handle the Can Bus or do you need the "canbus work around" module from Subaru Gears, too?

If you're running a standalone the CAN bus doesn't apply any more unless you're trying to run an auto.

It kinda depends on which 6-speed you are referring to. the STI 6-speed is too long to fit easily. If its the newer 6mt, which is already cable shift, I believe its the same dimensions as the 5mt, but the ratios aren't really any better.

I have been debating building a 6mt box with custom ratios though, might be pretty potent.

The 5+1=6 speed cable shift was just a bad idea from the start. Take a 5 speed who's original design was meant for 80hp and already self destructs at 225hp and narrow all the gear profiles to fit another gear. To make it that much worse there are no interchanging parts and aftermarket parts are almost non existent.(Most of the motor press commented that they would rather drive the automatic version of the car rather than that 6 speed when it was introduced (IMG:style_emoticons/default/laugh.gif) )

The STi 6 speed is very closely modeled after the Porsche units (rumors were that Porsche engineering was hired for the design but no proof). They usually break right around 550hp depending on driver. It's gear clusters are roughly double the size of a 5mt. It's internal oil pump (with a 1 year exception) can also be used for an external oil cooler and the list of advantages goes on.

The FFR 6 speed conversion cuts off the tail section so length isn't really an issue but I believe trunk floor clearance may be too tight.
