That someone is ME. The actual length of the adapter/axle is not that big of a deal as long as the engine is in the "correct" location - IE centered on the axle centerline. I am still working on getting someone to make these dang parts.

so i called a machine shop near where i work and found that they can do axle resplining or adapter flanges for a good price. they are fairly busy and so werent interested in a huge ammount of orders but said 30 orders over some time they could probably do. anyhow, my two questions for you all are- has anyone measured the subaru CV shaft and seen if it could fit? i wonder because if all we had to do was respline it (assuming it was a bigger spline section than the 914s) is fairly easy and inexpensive. the shop told me that if it was just a matter of heat treating the subie shafts and lathing them then resplining em, about 150 or so per axle, possibly cheaper possibly more.

they actually build complete custom CV's for the military (extreme use for special forces) that run 1100 an axle, but that is so extreme he said it wouldnt be near that to build an axle for moderate power and real world useage.

the other option was to build a CV adapter plate to fit either the 914 CV shaft or the 944 CV shaft, he said no problem, bring in both axles and how long it has to be and he can make em, similar price to the 150 (he said likely cheaper if it's a simple design).

my main thing is- does anyone have exact measurements for the subie output stubs (and inside diameter of the oil seals on em)? and also the lengths between them and the wheel bearing on the 914? I've found some specs on 914 axles, but if anyone has ready facts i'd appreciate it. i'm slowly cobbling together things for this swap and saw that it had kind of stalled on the board....

Scott


Hi Scott, It's nice that you are trying to work this out. The only problem that I can see is that the overall length will be different for each conversion because the motor and tranny can be put in many different positions. The general idea is good but you will need to make your own measurements for your application. Someone has already fabbed up a prototype flange to take the subie axles but the machine shop fizzled. I haven't gotten that far yet to study the possibilities but I'm sure others have.

wahoo, finally!! Must be xmas - Subie/ 914 adaptor!!!!!!

I was checking my email and what do I see? Something from the shop that I had given up on.

"Steve, after many backwards updates from our manufacturer (prototypes they've proven slowest at!, but their knowledge and skill I can't step away from) I'm VERY happy to tell you they're done"

I am supposed to have pictures and prices Friday. I will post them once I have them.
Finally after over a year - the magic part is completed!! I guess I will have to start working on the car again.

What are the gear ratio's of the subie tranny? I would suspect they are taller that the 914.

The axle assemblies are just stock VW Bus axles. Custom axles were one of the things I wanted to avoid at almost any cost. If you use the 944 stub axles the bus axles assemblies will just bolt in. If you want to retain the stock 914 stubs (or reuse your redrilled stuff) all you need to do is pop off the outer CV add a small ring spacer (I will make these for a few $) and slip it onto the bus axle.

Here they are!!! (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/piratenanner.gif)

No pricing yet, but I can guess they will not be cheap.

Look here for Subi gear ration stuff. Subi Gears

And here for Porsche ratiosPorsche gears

I posted this a while ago.

Here are the "way to tall gears"
US WRX (stock tire 205/55-16) Tire circumference is calculated
Gear Ratio Final drive Total ratio Tire Circ. Rev./Mile
1st 3.454 3.9 13.4706 78.15639 10920.38
2nd 1.947 3.9 7.5933 78.15639 6155.753
3rd 1.366 3.9 5.3274 78.15639 4318.828
4th 0.972 3.9 3.7908 78.15639 3073.134
5th 0.738 3.9 2.8782 78.15639 2333.306

I don't have the 901 ratios handy but I remember they were pretty close if you have the 4.11 or 4.44 final drive in the Suby. I think many of the Legacy FWD had taller gears (3.7 final drive)
The NA small engine (like 1.8l) transmissions had the "better" gear ratios (closer and lower final drive)

Steve what is the black coating? They really look nice. When will they be available as just a set? I will need to find longer axles to go with them but don't have the length figgured yet.

I don't kwow what the black coating is, probably a rust inhibitor or that gunmetal bluing stuff. That is a picture that the shop emailed me, I havn't seen the parts myself.
Why do you need longer axles?

The black coating is probably a black oxide treatment.
The flanges look Great!

What holds them onto the splined inner stub? Circlip?

I think you are right, couldn't think of that term before posting. The flanges are held on with a roll pin (a big one) driven thru the flange and the stub axle.

I got the pricing from the shop. I am paying $575 for the first pair. If I can get buyers for 5 sets the price will be $495 including shipping within the US. Delivery will be 3-4 weeks but I would plan on twice that much time.

Some details on the flanges.
"Turned from aircraft quality chromoly billet (4340) then vacuum heat treated and
chryogenically treated to -300F for maximum strength and toughness"
