Did the stubs stay the same throughout the 944 model years?

no. the two different 944 setups have different length shafts and stubs as well ...

i got my stuff off a 944 turbo, but i don't know the year. i can find that out tho as the donor car is just 5 blocks away from my house ...

Andy,
I bet $5 it's from an 86 turbo, there were big changes underneath for 87.

what if i have 911 hubs that fit the 914 wheel bearing and i use 911 stubaxles and halfshafts and change the drive flanges on the transmission to 75-76 911,
whouldn't that work just fine ???

Only if the c/v's are 100mm and the 911 axles are supposed to be too short anyway. The earlier 108's require the earlier stubs and output flanges. With Cays config the 944 c/v's have the 914 (VW) spline and you could use the 914 axle shafts.

You don't have to change the axle shaft if you use the 944 axles. The 944 and 914 axle shafts are the exact same length.

If you are a cheap bastard, you can buy a 944 stub axle and one CV joint, and put it on the 914 /4 axle. Then use the 914 inner CV and drive flange.

If you want to do it right, use the 944 axle complete, and the 75-76 911 transmission drive flanges.

Oh, and using a 911 axle is asking for a failure. They will bolt up, but if you EVER hit full droop or full compression you WILL bind the CV joint and damage it.

Then you will be out the cost of the 911 axle parts, and your 914 will be back home on the jackstands.

Here, Clay says the 914 & 944 axle are the same length. But Andys pic, shows the 944 axle is longer, is it the right year?



For a 4 cylinder teener, this would be a cheap way to do a 5 lug conversion, once everything is worked out?

For a V8 teener, I wouldn't do the axel and CV upgrade, unless you have a 915 or better tranny.

WHY?

It's cheaper to replace CV's than it is to replace 901's, especially if you've spent money on a intermediate plate and or H gear.
If, you beef up the CV's and axels, to handle more HP
than the week link becomes the tranny.

This is my 500,000 cents, the price of a nice tranny. (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif)

Hmmm..... It looks like 944 CVs are the same as 911 VCs and VW Type 2 CVs. I thought the are narrower and wouldn´t need any modifications. I have done this same with Type 2 CVs.

i was expecting it to be harder to cut those axles, but it was not too bad....


I was just going to ask that. We couldn´t use normal blade. We had to grind the groove wider.

Good work Andy and good pics !! (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

Those CV's are still smaller than the early 911 CV's I showed Andy yesterday, the 911 axle for sure is shorter as well.

I used a carbide cutting tool, 325 rpm.

with a V8 teener, you *WILL* break the 901 anyways, just a matter of time ...

for a /4 or /6 conversion, i think this is a great way to get true 5-lug in the rear, the bigger CVs are just a added benefit as 914 CVs are NLA but you can still buy the 944 CVs brand new ...

Added benefit. If the tranny ever does blow, you can replace it with a 915 that has the same size CV joint, and the fine splined aluminum case.

Do you have to machine both ends of the 914 axle shaft or just one end?

both ends as i am putting 944 CVs on both ends ...
the machining is needed to accomodate the wider 944 CVs. while the splines are the same, the actual 944 CV is ~4mm wider ...

Ok. I dont remember how much the splined center of 911/T2 CV was wider than 914 CV, but the difference is not big compared to 944 CVs (4 mm). So, this same concepts works with 911/T2 CVs too, right ??

If we could have and drive legally V8 teeners here, I am sure I would build one. Then I would consider very carefully using Renault UN1 transmission. They sell conversion bellhousings for SBCs, SBFs and Buick/Rover V8s. The tranny can handle 400 bhp. LINK

i believe the spline is different for those and they won't fit the 914 axle ...

According this LINK the width of splined center of 944 CVs and 911/Type2 CVs are the same 28 mm. Even the 930 CVs have the same width, but they have different number of splines and dont work with 914 drive shaft.

No, they have the same diameter and number of splines. Like I told before I have done this same conversion with 911/type2 CVs.

No no, that means that there are lots of space for bellhousing. (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)
