Yet another 5-lug rear conversion, some questions Options

[TonyAKAVW]

Craig: Nicely done! I think this is what mine will look like in theend. It looks like you left the cable end holder in the stock spot. Is the stop plate and 'rubbing pad' piece welded to the trailing arm? I can't quite tell from the picture.

Are those Boxster calipers?

[Richard Casto]

Looks good Craig! (IMG:style_emoticons/default/smile.gif) I am also curious if you were able to leave the cable end mount in the stock place or not. I am assuming that is a stock 914 cable with a custom extension correct?

I've adapted the 944 e-brake spreader to my car and have been using it for 3 months now it it works great.

What a "teaser" photo!!

Looks like everything was addressed. I really like it.

How about more information and photos. Please don't tell me that you fab'd up the whole thing and didn't take photos.

It looks like he also used the angle iron to make the block and rubbing support. Great job.

One last thing to mention. Brad may know something beyond what is listed in PET, but I just looked up the part number for the 986 and 987 and as far as I can tell they list a different part number for the bearing than they do for the 914. Frankly I would be suprised if they used the 914 bearing. They increased the bearing size in later cars (probably due to load from increased weight and performance of the newer cars) and I would not expect them to go backwards with the Boxster. But I don't know any more than what I can see in PET.

According to BR, the Boxster and 914 bearings have identical dimensions, but the Boxster has a higher ball count, hence the different number.

Ok, drop in replacement, but not same bearing. Good info for me to use on the wiki article. Anyone checked the price yet of the 914 vs. Boxster bearings?

[TonyAKAVW]

Boxster Bearings at Pelican Parts are $36.75 versus $77 for 914 bearings. I will probably use a Boxster bearing to replace my 914 bearing that I had to destroy in order to check if I had a spacer.

[charliew]

Tony use the junk bearing in the castings while you are welding on them to save ruining a good one.

What is the spline count and diameter inside the hub? Or another way of saying this, what stub axle will work with that hub? Will only the Boxster stub axle work, or will others?

If only the Boxster stub axle works, then what is the CV joint situation with the Boxster stub axle?

BR indicated that the Boxster stub-axle and outboard CV are one piece and are non-serviceable.

Meaning that the Boxster stub-axle is a likely a dead-end for 914 driveline conversion, at least as far as a bolt-up solution is concerned.

[charliew]

I bought a 944 stub axle on ebay. When I got it, it had the outer part of a cv made onto the axle stub. You might be able to put the 914 cage and balls inside the cv/stub. I really don't know if it was a 944 or a boxter part. It was so cheap I thought I would see what it was.

Thanks Tony
I've got boxster calipers front and rear.

I left the cable end mount in the stock location but cut it off to line up the cable to the spreader and rewelded it back to the trailing arm. I fabed the shoe anchor out of angle iron and welded it to the trailing arm.

I was going to do a thread on how I did this or would you like me to add it to yours.

[TonyAKAVW]

Please add it here!! Would love to see that. I think I will take a look at Boxster rear calipers, might be another option to consider other than the M calipers...

Are you running 15 inch wheels with those calipers? I have 15" cookie cutter wheels and would like to keep using those...

Ok I'll start adding some tomorrow. I have the early 15" deep 6" fuch and they just fit.

Craig;

I think it should be on a new thread!!!

This string starts out covering a lot of stuff that isn't specifically about e-brakes.

I'd hate to see what you have done get buried where people don't see it without reading three pages.

Wes V

[TonyAKAVW]

Wes is right. It would be a lot easier to find if it were in its own thread.

And be sure and say using the angle spreader, that spreader can be bought by itself as it's also on bmw's, and the support with the rubbing blocks and the 914 extension. For the guys that have the early shoes already they can use them with a small notch ground in them and if they ever wear out then they can go to the 944 style shoes. There is a straight pull that looks very much like the angle pull so be careful on buying the spreaders by themselves. The straight pull, not the early 911 butterfly type, are on the earlier aluminum bananna arms, I think about 74.

I found at least two porsche yards that were very familiar with the individual pieces of this conversion. When I called the yards they said yeah you want the 65-68 911 backing plates off of the steel arms (I don't think there are any alum. ones anyway) and the rest of the stuff off of a 944, it'll take a coupla hours to take the parts off. It was about 160.00 to my door. Make sure you ask for good useable shoes and the least pitted backing plates they have.
