Not done yet, look at the difference between the FWD and the AWD transmissions in the car.

hey, is your fwd from a 90-94 legacy, or from the later impreza? Reason i ask is my fwd is from a legacy and i want to put an lsd on it like you but i dont know which lsd fits my trans since it would have to cross over from a 5mt AWD, but which one? Has anyone suggested yet, to use the subaru inboard cv and the 944 outboard cv with a custom axle from the driveshaft shop or other co. ? The driveshaft shop has subaru cv's that handle serious hp. If the 944 axles are to long the weld up flange wont be possible (early 924 to hard to find) and i will probably go the other route i mentioned above. |

Yep, a few pages ago. That would require a true custom axle not just a non-standard length one. I also don't think you could take the axle out of the car without removing the trailing arm. I'm not sure how this works on a Suby. Normally on a FWD car you have to partially disassemble the front end in order to remove an axle shaft. Keep the ideas coming - we can figure out a great way around this little problem, I really don't want axles that cost more than my engine.

Here are some sites that were recommended to me from an STI owner when I asked what he thought I should do to strengthen the WRX gearbox.
Personally, I am going with straight cut, dog engagement. Fast, positive, strong as hell and just as niosy. Site #1 has a good video depicting "dog" style shifting. It was love at first watch for me. 5 speed AWD gearsets #1 5 Speed AWD Gearsets #2 |

I keep thinking about this. Wouldn't the KEP adaptor work "backwards" the holes should line up. The flywheel won't work. |

I have found a shop to make flanges for the project.
What CV's do you guys want on the transmission end? I am leaning toward the 944. This let's us use other 33 spline axles like the 911. I am planning on paying about $350-400 for the pair. These will be top quality US made parts that will not break - period. |

I "think" the axles are a larger OD on the 911 units, so the 944 CV might not work if the spline OD is larger as well (you'd think it would be since a larger OD axle would be silly to have a smaller OD spline...weakest link sorta thing)
is that price for just a pair? price break for multiple sets? |

Steve,
Whats the width of the Suby transaxle output flange to output flange? If close to the BoxsterAudi transaxle (I'm using) it could add quantities when getting them custom made. Commonality has it's benefits. I will use 911 CV's 108mm = 4.25" dia... |

the bus axles would work for 944 cv's. they are an 1.5" shorter than 914 with the same spline.

Hi Felix, This flange does not exist yet, so I can't answer that. The distance between this non-existent flange and the wheel side flange I am developing will be 1 or 1-1/2 shorter than the 914 so we can use 911 or Bus axles. |

Steve, what I meant was the dimension between the flanges on the transmission. The transmission width between it's flanges will dictate the axle length. I expect they will be longer than stock which will require an adapter or custom length axle. |

If Steve ultimately uses a fwd rear housing on his awd tranny with the two most rearward awd sections removed - I'd guess he would not need the plate - but would only need the sleeve??

you remove the awd sections, thats why you need the rear plate. Otherwise there is a big whole going out the back for a drive shaft/universal....The two pieces needed are shown, plus it will shorten the tranny for a better fit...

The way I see it from the pics in Steve's blog and his writtings is that he plans to remove both sections and us a fwd rear housing which would negate the need for the plate. The plate would be needed if only the last one section were removed?
Personally I think using the plate and removing only the last section would save sourcing out fwd rear housing and the space gained still may not allow a single muffler to be used. Probably best to run dual exhaust with short mufflers on either side of the tranny? http://www.914world.com/bbs2/uploads/blog-1...-1139236938.jpg http://www.sakercars.com.au/assets/aus_gal...ry/106_0663.JPG Jim |

I haven't got my parts yet - maybe later today. I will know this weekend if the FWD cover will work or not. The point of my trying the FWD cover is to avoid any modifications to the car. The AWD will work fine if you just "clearance" the car a little bit - I don't want to do that if I don't have to. There should be plenty of room for a good muffler with the FWD cover in place.
BTW - I am one step closer to getting the flanges made. I decided to go with Bus CV's on the transmission side. These will allow us to use the stock 914 on the wheel side or use the 944 setup if you want a cheap strong 5 lug setup. I am hoping to use a stock Bus axle. |

Cover - as I understand it - is the same rear cover as in the top pic on page 12 - if it fits.
The problem would be tracking down these rear fwd covers and seeing it the aussy's would alow orders for just the sleeve. im |
