    Electronic Speedo conversion to cable-driven - has anyone done it??

    Is there a way to be able to retrofit an older CABLE-driven speedometer in a stock Fiero with a V6 and 5-spd tranny??
    I want to be able to replace the standard electronic Fiero speedo with a gear-driven speedo.

    I found a kit on the Net which looks promising for VW older cars but I'd like to know anyone has attempted such conversion...The reason I'd like to use the cable-driven/gear-driven speedo is because I want to retrofit a Fiat cluster on a Fiero. Just a thought!

    How about NO.

    It can be done but it will cost a small fortune to dyno set a gear reducer combination, custom made speedo cable and custom made transmission adapter.

    Your best bet is to buy an electronic speedo head (I know the VDO) and make up a pick up either with original speedo sender or by making an ABS sensor work with six or eight pulses per wheel revolution.

    Cheers;

    Thanks....I didn't think it was easy or cheap to do but I thought to ask just in case someone was crazy enough to have tried it...

    Jim is correct. Bring money!

    Most front wheel drive Getrag's use a steel pick-up cog on the differential carrier for the speedometer. This will need to be replaced with the plastic gear used in the Fiero. Any 85-88 Manual speedometer sending unit will work. The GM part # is 8672319, about $10. To install this gear, you will need to "split the case". I have all the necessary instructions on my web page to accomplish this task. While this sounds difficult, it is actually "very doable" for the average do-it-yourselfer. The correct sealant to use between the case halves when reassembling them is Locktite 518 gasket eliminator flange sealant, although silicone will work just fine. A GM dealer will sell you the 518 sealant (their packaging) for a lot more than if purchased elsewhere. It may be hard to find elsewhere though.

    Thank you for the info and diagram Dave....It seems like you've been-there-done-that already...

    At the present time I'm just throwing around different ideas as far as using a more "authentic" looking speedo in a 308 replica....I don't really like the looks of the VDO gauges, which everyone seems to be using in their Ferrari replicas. Some of the older Fiat gauges look very close to 308 gauges and I have a few spares of those. I certainly I'm not going to re-invent the wheel nor spend a ton of money of this conversion....I might just end up using an electronic speedo and Fiat gauges and change the face on the speedo to more authentic 308 look.

    Regards and Happy Holidays

    There are a couple units available to do exactly what you want.
    http://www.atrol.com/cablex.htm , this one sells for about $300.

    There is another one from one of the aftermarket EFI companies, but I can't find it right now.
