916 gearbox conversion kit (915 to 914) Options

[Steve]

I only know of two installs. The one in this thread and one in another thread. Neither of them show the shift linkage, but one of them used parts from Patrick Motorsports. Here is a link to the other thread. http://www.914world.com/bbs2/index.php?sho...=109782&hl=

Steve,
thanks for the link. The thread on the link however has no feedback. No real details, and definitely no pictures.

I really want to hear from someone whose installed the kit and run it for 500-1000 miles or so. Some one has got to have done that by now.

Please post. (IMG:style_emoticons/default/biggrin.gif)

I would PM both turboman808 and mharmon for feedback. They might not be subscribed to this thread.

What are the difference between this kit and the Wevo..??...(+ vs -)

Martin's setup is pretty much a duplicate of the factory 916 Trans.
Positive side versus Wevo
-Better shifting, because the shift rod is shorter? Maybe, maybe not?
-Allows use of stock mufflers
-Worth more? The last "real" factory 916 trans on ebay sold for over $15k
Negative side versus Wevo
-More expensive and price varies based on the Euro vs USD.
-No aftermarket shifting linkage that I know of, but I have heard that Patrick Motor Sports could make something up for you.
Positive side for Wevo
-Lots of good feedback.
Shifts great, well designed and reliable.
-Lower cost for kit
-PMS makes all the parts including the shifting linkage for our cars.
Negative side for Wevo
-Trans is to long to use standard muffler. Requires either dual mufflers or extend your headers and use a skinny muffler like M&K.

The above is my humble opinion from my own research. I have never driven either one of them. So take it for what its worth.

We've done both conversions for customers at CFR-TRP.
IMO, price aside, the 916 yields a better final product.

Re the 916 kit: We were sent a duplicate of the 916 upper support for the selector shaft, which required some welding and machining to install in a 915 case. I haven't seen the upper support designed specifically for a 915 case, however I did receive some feedback in a conversation with Peter Dawe. Apparently there is considerable clearancing required to make it fit.

The WEVO kit isn't easy to install either and has its own problems, some of which were elaborated on in Steve's post.
Internal clearancing is required for the shift rods to function. The o-ring seal on the rear cover sucks, and is likely to weep gear oil.

Chris,

thanks for the insight. so this 916 kit is not a plug and play for the weekend person like my self. yes I have no machine shop in my garage.- correct?

... so this 916 kit is not a plug and play for the weekend person like my slf. yes I have no machine shop in my garage.- correct?

I think the Vellios kit could be installed as plug and play, but it isn't available any more AFAIK. Neither the WEVO nor the 916 kits are simple projects for the DIYer.
Even the Vellios kit would require machining to install the factory style 915 speedo sensor though.

Edit: I've heard that the Vellios kit may be available at GPR.

[turboman808]

Well not sure what feedback I can give other then everything works really well.

I can now shift with confidence.

[Loser_Cruiser]

The exchange rate is killing my dreams right now, but assuming that turns around someday, does I'm still curious as to if you can use the -4 style shift rod or if it needs the -6 style shift rod. Turboman? Whats your setup there?

Hi together,

here´s a picture of a 915 we made a revision and converted to 916. It´s for a 914/6 with a 3.2 engine.

Hello Martin
Please provide an update on the 915 - 914 conversion.
I'm very interested in using a 915 in my 914 3.0 conversion.
Best regards
Rory Gallagher

@rgalla: sent you a PM

in general:
kit is running well. In the meantime we´ve upgraded the mould of the nosecone so that mechanical speedo drive can be installed now. Customers are happy with the kit. The kit is not seen as a further Vellios or Wevo kit, but people see that it is a repro of the legendary 916 kit of Porsche from the 70s.

Hi,

some pictures of the new nosecones with the upgrade for the mechanical speedo drive. Currently have a long lasting order for industry on my milling centre, so that parts have not been finnished milling for the speedo drive. At the moment they can already be mounted to a electronic speedo gearbox. Hope that I can do the final milling by end of next week. You can see our prototype where we welded the position for the bearing of the speedo shaft. The other picture shows that the mould was adjusted in some places, especially to hold the speedo-parts. Also see the mechanical parts for the speedo drive that we already prepared (only minor adjustment have to be done still). Will keep you informed and will give further info as soon as parts are done.

Once again Martin, a beautiful product.

I'm still sitting on the fence due to the economy and the Euro.

I can't help but notice that due to the Financial mess in Europe that the Euro is slowly beginning to drop, which for us here would be a great thing.

What, is the 2012 price for your 916 kits in either electronic, or mechanical speedo form???

Ron

[bugat5speed]

Hi Ron,

thank you for the compliment on the parts. Yes the Euro is falling a little, but don´t think that it will be that much. Prices for the kits have yet been stabile and are for export to somewhere outside the EC:

916 kit for electronic speedo - 2.092 Euro

916 kit with mechanical speedo drive - 2.428 Euro

UI uderstand that you see a higher price than for another exisiting 915 conversion kit, but if you want to build an authenic car my kit will anyway be the best choice. Please be aware that the last original 916 kits were sold at prices around 10.000 Euro (a few years ago).

I am willing to help the one or other to do his decision although Euro is still not as low as most of you wish and offer a 3 % discount on both products until end of June. Can´t do much more as production costs on these parts are highr than I originally calculated. I will in the end be forced to increase the prices one day.

Hope to have helped you a little on this matter.

This sounds like a place where a concerted group buy from 914World members, maybe Pelican, Tangerine and RedLine included would help stir an interest, provide a bulk discount and help soften your raw material and machining setup/costs.

I have a bad habit of thinking too much while unemployed, as I was a bit of the idea man at 3 previous jobs.

1- Does this stir an interest in the 914World family?
2- Price point that would satisfy?
3- Production number to satisfy the above and make it work?

Have to ask details:
4- What would it take to tie it to a Suby or V8, as many are still heading that way?

Sorry to Hijack, but the group buys usually stir more interest and feedback if not happy customers...

[wingnut86]

...additional thoughts.

5- Provided a group buy works, maybe a few units could be sold to members who will be attending transmission clinics hosted by group members. That way, one of our experts can refresh a 915 in a group setting and add the 916 kit with all watching...

Marketing 101

[bugat5speed]

Hi,

who would be interested in such a group buy. Can´t promise too much on prices, but will do what I can. I personally would be interested in figures from 8-10 kits. Currently could offer 3-4 kits at short notice, but could get more (from faundry) within 6 weeks.

If I see that you are intersted I will make an offer.

So please let me know by PMs who would be interested.

What concerns Subaru or V8 it is so, that an adapter is needed anyway, but I think you know that the 915 stands upto 350 Nm about. You must know torque what your engines will give. So it´s not question of my conversion kit, but of the gearbox anyway.

Martin

[bugat5speed]

Had some days time to do work beside the industry-orders on the CNC Mill. Put the nosecones on the mill again yesterday and milled the place for the speedo drive. Pressed bushing inside and tested speedo drive (as far as I could - shaft is not turned or not finally turned). Works fine, just as on the prototype. The shaft of the small speedo drive will be turned within the next few days, then the 916 kit will be available with mechnical speedo finally. A further argument for the 916 kit.

Martin

Btw: Euro is really dropping and lost some percents in the last two weeks. Is there still an interest of a group buy?

[seanery]

I would love one of these, but I'll have to wait, more things to do first.

[mharmon]

The kit that I purchased from Martin has has been installed on my gear box. The car came back from paint, so hope to have it and the motor running in the next couple of months.

Will report back once it is.

I am in the same boat.. I received the transmission back from the builder, but it will be a couple of months before I get it back together. The builder said the kit was very high quality and required little work to install it.

[db9146]

I am interested in a kit but I would like to see a little more feedback on the shifting performance once behind a running engine.
