That's a Suby AWD trans converted to RWD with 2 parts <!-- emo&:beer2: -->(IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)<!-- endemo --> Convertor sleeve: AUD$120.00 Blanking plate: AUD$110.00 If bought together, total price AUD$210.00 Looks like a side shift linkage could be tweaked to work. I just bought a 2005 (EJ25) engine and trans (2000 miles) for the 914 - let the fun begin. I just sent an e-mail to sakercars to check on parts availability.

Here's my two cents: I have a 500HP LS6 crammed into my 74 and have learned a few hard lessons along the way. Of course, my car is a bit extreme and requires a more robust gearbox than most projects out there, there are a few freaks (like myself) that want to explore insane performance and at the same time have a certain degree of reliability. I would say that if your project gets close to the 400HP range...you are now entering the broken 915 transaxle zone...and often! I started with 450HP and knew a 901 wouldn't handle it...so I had a 915 built at CA Motorsports (LSD, tall 5th, reversed ring & pinion, etc) to the tune of $4,600. I put 2K on the car and blew 2nd gear off the shaft! I rebuilt the trans again at CA Motorsports, upgraded my motor to 500HP and said goodbye to the 915 on E-Bay. The guy who bought it has around 400HP and should have way better luck with it. Now what to do? With an open budget, the best option is a G50/50 turbo transaxle inverted and connected to a custom cable actuated sideshifter. Here's the problem...I don't own Microsoft and don't have $12,000-13,000 laying around. Believe it or not, that's what that system costs w/ clutch and all. So I ended up having my favorite trans expert, Bobby Hart of CA Motorsports, build be a reversed ring & pinion, short bell 930 turbo gearbox. It won't shift nearly as well as a modern G50 series gearbox...but it'll handle over 700 HP with the use of an oil cooler and Tilton pump spraying back on the R&P. What's more is the gearing is roughly the following: 1st gear = 60 mph, 2nd gear=90mph, 3rd=130mph+, and 4th=190mph plus (assuming my Sheridan body work is as slippery as I think it is. The 930 Box will cost me around $6,000 (I found a cheap good core for $500). Most cores cost $1500-2,000. So, the moral of the story is simply...."If you are running 400 HP or more and don't want to shred your gearbox every other weekend, you'll spend between $6,000-8,000 for a proper gearbox with usable gear ratios." If you've had better luck with the 915 than I have...I'm happy for you and wish you continued good luck. Perhaps I'm a bit hard on my car at times? I just want reliability and although I'm not rich...I'm willing to spend a bit of $ in the gearbox department. As far as Audi, Subaru, Renault, etc. I think their gear boxes can be made very reliable for motors putting out 300-350HP...any more power and you are entering the "expensive broken gearbox zone". Just my two cents...
