anyone got a working setup of a cableshifter in a 914 using a 915 transmission?

if so, can you please post specs and pics ...

i'm highly interested ...

What is wrong with the best solution out there...WEVO?

PS: why build a turbo T4 for your 912? what's wrong with the best solution out there ... a porsche 3.6L six?

Sorry - couldn't resist!

Posted by: Brad Roberts Jun 27 2006, 03:10 PM

Andy,

call Renegade Hybrids and see if they still sell a solution. I doubt seriously you are going to find anyone outside of Renegade selling a cable solution.

Patrick Motorsports and Renegade sell the same setup from Cunningham.

You can fab your own, but I wouldnt do it with a fresh box.

i think "drive-ability" started with a renegade box and then went to an import shifter? mitsu or toyota iirc

Posted by: SirAndy Jun 27 2006, 03:30 PM

yes. i did. couldn't find any pics of a working setup. that's when i posted my post.

so, you got a link to a post with pics of a working install?
Andy

Posted by: TonyAKAVW Jun 27 2006, 03:35 PM

Here's a picture of a cable shifter, though I think that transmission says 930, but I don't know.

Anyway, this was on a silver 914 that showed up at one of Joe Sharp's BBQs. It was the one with the raked windshield, nascar V8 engine, etc.

Does that tell you anything Andy? LOL

I only know of .. well.. nobody running a cable setup on their 915.

I'm willing to bet all the racers with 915's have gone to WEVO.

The above picture is a 930 box.

I seriously cannot think of anyone in the USA running the cable shift setup on a 915.

We had one guy from Germany post asking questions about his cable shifted 915, but I didnt see any decent pics from him.

Obviously I dont know everyone, but I have a good grasp on most of the people running a 915 in their 914.

Andy,

I'm too poor to get the Wevo setup right now, and my current mechanical linkage isn't very good (Rod Simpson).

I am seriously considering creating a cable-shift solution for my car in the near future. I spoke with Scott at Renegades lately and I think he said his cable setup was ~$800.
Bolstered by seeing the recent cable projects (901 & 930) by others here on the club I believe that I can make something for less than that.
If you'd like to brainstorm and work jointly on a solution I'm willing to give it a shot.

Posted by: jkeyzer Jun 27 2006, 04:28 PM

You guys might want to talk to bondo and see if you can talk him into developing one with you.

Posted by: nocones Jun 27 2006, 04:43 PM

Bondo did such an impressive job on his!
If I recall he said there wasn't much chance of him having the time to work on such a setup for the 915. (Bill P. and I both asked)

Posted by: SirAndy Jun 27 2006, 04:58 PM

yes, sir!

Andy

Posted by: nocones Jun 27 2006, 05:01 PM

I've been meaning to wander down the street to pick n' pull and have a look around for a suitable shifter to start with. It sounds like the McMaster-Carr cables are reasonably priced and the rest could be fabbed without too much trouble I think.
I've got a friend with Solid Works and access to a machine shop so I was thinking of hitting him up to help in designing/building the parts for the attachment to the trans.

Posted by: Andyrew Jun 27 2006, 05:05 PM

I'd like to help as much as possible as well!

One of the slickest I've seen recently was from "wbergtho", but I'll be damned if I can find his thread/pics for you. I know they were posted at one time.

Posted by: Brad Roberts Jun 27 2006, 06:12 PM

Interesting. They are changing the direction of the "front 2 back" cable.

I think we talked about the Boxster/996 shifter already having the correct "direction".


B

Posted by: wbergtho Jun 27 2006, 06:30 PM

I built my own cable shift version to shift my 930. A 915 shifts about the same as a 930 (similar design). I am absolutely sure if I went back to a 915, my system would work as well as it currently does. Here are a few pics I took before I prettied evrything up and had it all powder coated.

*McMaster-Carr 5/16" cables (84" & 96")
* Mitzubishi 3000 GT shifter (modified to place the fore/aft rod end attachment point above the pivot point of the shifter...to eliminate the need for more "monkey motion" levers, etc.)
* Custom made trans mount
* Splined drive shaft from a Geo Tracker & splined hub
* A cage bracket to limit the side to side hub/lever
* Time & patience


Regards,

Bill

Nice design! Works for me!!

Posted by: jim912928 Jun 27 2006, 06:49 PM

I'd be in for a kit...i've got my 915 sitting on the side...currently debating what to do!

Posted by: Brad Roberts Jun 27 2006, 06:52 PM

Bill,

did you drill/tap the shift selector sleave for a cone screw? so it would enter the recess in the stock shift selector rod?

Or did you cut it off and just use a "jam" screw?

I see you played aorund with the amount of movement needed for the "side to side" motion.

Combine this and the WEVO gateshift and I bet it would be pretty solid.

Did you take a look at how the Boxsters do it? They have counterweights on the linkage to make it "feel" correct and to assist with the gear change.

Pretty slick


B

Posted by: wbergtho Jun 27 2006, 09:12 PM

Hi Brad,

I took a stock cone screw and tapered the "cone" section more so it would bury itself low enough to keep from binding. I have not looked at a Boxster shifter in the flesh but have seen a few pics on this site. The counter balance design sounds interesting. I just may do further investigating on the Boxster shifter as an upgrade to what I have. My shifter is decent...but could be upgraded to one that is of higher quality (less slop...better feel). Most anyone could jump right in my car and never miss a shift or have any difficulties finding all gears...but it can always get better. I just wish the 915 & 930 gearboxes shifted better & faster. I guess we're stuck with 70's technology here.

Bill

Posted by: kdfoust Jun 27 2006, 10:17 PM

I'm plowing the same field Andy. I found this over at Patrick Motorsports. Looks like some kind of a cable shift. I can't find any pictures of what PMS is doing at the tranny end.


It looks like this http://race-cars.com/carsold/porsche/1137455863/1137455863ss.htm is using the PMS cable shift. There's ahttp://race-cars.com/carsold/porsche/1137455863/1137455863pg.htm but the linkage doesn't make any sense to me sense to me. I'm not familar with the 915 setup yet.


Regards,
Kevin

Posted by: Andyrew Jun 27 2006, 10:28 PM

The rod sticking out the end of the trani goes in and out. and twists as well. which selects the gears.

There are two cables on that trani, One pushes and pulls on the rod for in and out.
One comes from under and twists the lever left to right.



Andrew

Posted by: McMark Jun 27 2006, 11:12 PM

Hmmmm..... with a shifter mounted on top of the center tunnel, you could probably run the oil lines inside the tunnel.

The 996/986 shifter looks really nice. I think we could cobble something together. Then the issue is mounting the tranny in the car. The WEVO gives you stock ears to mount it, which is really clean. The whole cradle mount doesn't taste very good to me.

Posted by: yeti Jun 28 2006, 10:22 AM

Hello.
Well I just saw the thread . Well I might be the one guy in Germany who run a 915 Gearbox with the cable shift system. I have the gearbox done by powerhouse and they also recommend the cable shift system. It is the same than from Patrick I gues. It should shift better and faster and it is still the cheaper version. I had (that is a long story - asked if you are interested) and have (still) some problems with the whole modification. I.e. how to fix the mechanical speedo cable to the gearbox. I posted this here - thanks, I might have even a simpler solution for this problem.
The gearbox is longer than the 901 and space for a "TÜV" exhaust system is pretty rare. Well I have no idea what you guys in USA are doing with the exhaust system with the 915 gearbox .
I made something that might work for the first but I will get a stainless version and heat exchangers in the winter time. The car still does not run - hope I will fix it this week. I got the wrong permatune . So there was plenty of changes on the car, but it looks pretty original and that was my goal. Since the car still does not run, I just want to use it now and fine tune it in the winter time.
The cable shift system looked pretty ugly if naked. I had no idea - when ordereing. I used a silver aluminium block to adjust it to the correct height and then fabricated a custon console to hide all the cables. I will add a few pics so that you have a look at it.

And the last one with the final console. Look at my gauges. Man I will be very happy to look at them ( you do not see the 300km/h speedo). I will use a nice Momo Prototipo covered in suede and make a custon sport seats (out from the original one - but this is a project for next winter).

Well a lot of problems come with the 915 gearbox. If I could choose again I would kept the 901 with a nice 2.5 sport engine that runs up to 8k UPM. But it is a very strong gearbox that could handle a lot of torque and that is the reason why I've choosen that. I have shift the gearbox a little and it was a bit heavy but a nice feel. It should be much more easier since the engine run and the system is used a bit more. I let a hole in the middle of the shifter so you can see the nice mechanical stuff.

Here is what mine looks like. It is from a Boxster.

Posted by: jim912928 Jun 28 2006, 12:33 PM

Sharper...can you detail out your work? Did you use the Boxster shifter in the passenger compartment? How much fab work? Can you post more pics of the inside and backside?

Posted by: sharper Jun 28 2006, 02:55 PM

Afraid I'm not much help here as I didn't do it. The guy I purchased this car from is the one who did it all. I can take whatever pictures you like though. Let me know what to key in on and I'd be happy to send them to you. It is a Boxster shifter in the passenger compartment mounted on top of the tunnel.

Posted by: byndbad914 Jun 28 2006, 03:32 PM

The Boxster/996 tower requires the direction to be reversed as well Brad. Actually that pic of Scott's new shifter setup doesn't look all that bad now. I have no experience with it, but I can assure you the PMS/old Renegade/Cunningham shifter is a complete POS as far as I am concerned.

Andy, if you have a buddy with a machine shop and solid works that is willing to help you, have him look at the car and come up with some ideas. Always good to pick the brain of someone that makes stuff for a living. I bought the Boxster tower and cables from a Porsche wrecker in the valley for $300. I ended up not using the cables as the McMaster-Carr stuff was longer and easier for me to work with. So, I would suggest trying to sources a tower only. I see that Sharper uses a rocker arm setup for the left-right selection and was able to use the shorter Boxster cables - though I hate the ends they come with. Rod ends are much nicer to work with IMO.

If you think you like the late model tower idea... suggestions to work from:

The tower isn't gated in any way, so that shifter can flop around like a wet noodle when not attached to anything. So whether you build a cable setup for a 915 or 930, they would be identical as the trans will drive the motion at the shifter. Hmm, not clear - what I mean is it doesn't matter where R is, or where 1st is, the end assembly will be identical between the 915/930.

You will need to make a bracket that you bolt to the back of the tower to mount the cable ends into. Use 5/16" cables as the quick-disconnect in that size is a perfect fit for the ball on the end of the shifter. You can drill and just screw into the plastic arm of the other one with a 5/16" fine-thread bolt.

At the rear, you will need a to make brackets to mount which shouldn't be an issue for a machinist. Either at the tower or at the rear, you need to reverse the fore-aft motion or the H-pattern would be upside down.

If you get a shifter for say $150, you could have the whole thing built (assuming friend's labor is free so just paying for cables, ends and metal) for $500 tops. Here are some photos of some of my stuff I made. I am going to build an even slicker "reversing" arm for the tube car that will be fully adjustable to set the shift pattern perfectly to what I like. 930s (and 915s IIRC) are notchy bastardos.

Shifter in car - notice my aluminum L-channel off the back to attach McM-C cables


And the parts I drew up in ProE to work from - these mount to the trans output shaft with the stock 8mm taper pin. Just suggestion - feel free to make up your own ideas working with your buddy. I use a 1/2" stud to "guide" that long "orange" arm fore-aft and stop it from pivoting loosely. You gotta see it in real life or really look at your own car to probably get what it going on.

My car shifted AWESOME. Notchy as f@#k, but that is the 930. I NEVER missed a shift or found myself wondering where 2nd gear was with this setup. And I could tune the exact pattern I like unlike all those other prefab deal-eos.


That is just for reference. The yellow arm and silver extension are no more (I had to add a spacer and arm so the two cables wouldn't bind - my new design won't have that).

Shitty but hopefully helpful shot at the rear while under construction.

Cool stuff!!

Posted by: byndbad914 Jun 28 2006, 07:23 PM

so I have a moment to add some more - this is going to be my new reversing arm out of aluminum. The slot and hole at the ends is 5/16" to match the rod ends. The end with the hole will mount to the trans adapter "orange" arm via rod ends screwed together (1 male and 1 female). The slotted end is where the cable will interface "single shear". The max outward distance makes a 1:1 ratio between cable motion and trans motion. That makes a pretty long throw at the shifter handle, so I can slide it inboard to tighten up the ratio (and therefore the fore/aft throw at the shifter) until I like how it feels.


the big hole in the center has a little sealed bearing that will slip into it that I bought from McMaster-Carr for $5-$7 IIRC that has a 5/16" ID. Looks like this more or less - the little flange is perfect for the overall design.


That slips over a shock hinge mount similar to this I lifted from this site - also from McM-C, but has a 5/16" "post" with a nice groove and snap retainer that fits the bearing perfectly instead of the ball ends. The part I bought was also about $5 and I hope the little post doesn't snap off. If it does, no biggie, I will just make a plate and 5/16" stud to do the same damn thing, but for $5 was better than fabbing no matter how simple the fab work


BTW everyone - get a McMaster-Carr book. It is about 4" thick and has every part known to man in it. I literally get an idea of what I want to build, pull out the Mc-C book and look up pieces to build around. I have spent hours just mulling thru this thing - sick I know.

Posted by: marlinaness Jun 28 2006, 09:21 PM

Just joined yesterday. Over the winter I built a cable shifter for my Porschevarri using an 86 915 with LSD tied to a 400 hp chevy v8 in an Eagle GT body sitting on a 73 reinforced 914 (probably one of the first Renegade kits built in 1982 or so). I bought it from Bill B of Wisconsin who swapped it for a 930.

I converted from an older 915 that shifted out of the bottom rather than the end.

I had to weld a new rear mounting bracket, used two Mcmaster 80" cables and a Honda Accord shifter. It works very well and cost about $250. Unfortunately, my first setup I had on the wrong side and it was reversed, so I added a longer bolt. Works very easy, no play at all. I will try to get pictures over the weekend. It is significantly better than the older version.

Nevertheless, I wished I would have known about this forum and seen the info here.

Andy

Posted by: Jeroen Jun 29 2006, 06:12 PM

from what I understand, that's the shifter mentioned earlier (patrick/renegade/cunningham)

I'm following with intrest. Eventhough I'm just gonna run a 914 box, but I really don't like where the stock shifter is positioned.

What I'd wanna know how the shifting feel is...
Is it accurate? Sloppy? Vague? Like a stock tailshifter or better/worse?

Posted by: Andyrew Jun 29 2006, 06:27 PM

AFAIK... a cable shifter will shift only as good and smooth as the trani behind it....

So if its a modern Boxster trani... it will shift like butter.... if its a 901 trani.. it will be sloppy and hard/crisp... (my rennshifted 901 is really sloppy... even with new bushings and everything... its the trani....)

Andrew

Hi Sir Andy,
well nice to read something in german
Well I would be happy if I could use a standart banana 911 or the "R" style exhaust. But as far as I know - no chance. What about the Wevo kit - I guesas the same problem since the 915 gearbox is longer than the 901. There is no room for it. I really like the Wevo style as well and I would have choosen it, if I had no recommandations for the cable kit and the extra price. But you really have to cover the cables in the interior if you are looking for a street car. I will post the shift feeling as long my car is running. I hope it does not take too much time.



Yeti

Posted by: SirAndy Jul 1 2006, 02:17 PM

for the WEVO kit, it looks like the endcover is much thinner, this *might* just leave enough room for the banana style muffler (which is what i have) ...

here's a pic of a WEVO 915 next to a tailshifter 901, it looks like there's plenty of room ...

WEVO or Cable Shift ?
Andy

Posted by: jim912928 Jul 1 2006, 06:58 PM

Andy, after reading this thread, others, seeing pics of backside and passenger compartments...I've decided to go Wevo. mounting to the car is cleaner, looks like you can use standard muffler mounting stuff, I've never heard anything bad about the setup, don't have extensively modify the passengers compartment. And for me I get better highway gearing (already have my 3.2l and it's original mated 915). Looks like I'm going to take the plunge!

Hello to all...

I am new to the board, so go easy on me...( )

I have procured an sti engine and a 915 transmission that will be going into my 914 shortly after it comes down off the rotisserie...which it will be going on as soon as I get the rotisserie built. cart, horse, whatever. Long story short, I am looking for a good shifter setup as well. I found some pictures of the branwood shifter http://www.mooreparts.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=MP&Category_Code=SHIBRAN The guts of the shifter have been cleverly concealed..but it doesn't appear to bear a striking resemblance to the renegade shifter.

Posted by: yeti Jul 3 2006, 02:09 PM

Hi.
Well Andy, are you sure that you have the same "room" for the banana style exhaust with the Wevo kit? The picture with the 2 gearboxes might do not justice to it. Are there guys here in the forum, that use the Wevo kit with the 915 gearbox? Or the Wevo guys should have an answer. You could messure the 914 gearbox and compare. Right, the Wevo kit looks clean and you do not have to build a console on the street car. But the thing is: you want to have to choose the best shifter system. That is just a recommandation of course - I got it from a company that have a lot of experience with gearboxes. I guess the know about Wevo. Well I will see if it runs.
The mooreparts shifter look the same than the PMS that I have in my car. Good price.

Yeti

Posted by: Brad Roberts Jul 3 2006, 03:06 PM

The stock 911 banana will not work with the WEVO setup. You have to cut a hole in the muffler and patch it back up. Fairly simple, but it has to be done. I think it would work with a Bursche header/muffler combo with mods.

The lower portion that says WEVO on it hits the banana muffler.

Where did all these new people come from ??LOL
