Title: 131 electronic ignition conversion Post by: fi131 on November 15, 2010, 09:30:52 PM Is it possible to convert a stock 131 ohv points ignition to electronic? It is a Marelli S147A point distributor
I have seen the above ignition pick-up set for marelli http://cgi.ebay.co.uk/FIAT-124-SPIDER-131-BRAVA-ELECTRONIC-IGNITION-PICKUP-/350090953686?pt=Motors_Car_Truck_Parts_Accessories&hash=item51830c03d6 and the above electronic modules http://cgi.ebay.co.uk/Fiat-124-Peugeot-505-Renault-R18i-New-Ignition-Module-/350320929940?pt=Vintage_Car_Truck_Parts_Accessories&hash=item5190c12c94 http://cgi.ebay.co.uk/Fiat-124-Spider-Ignition-Module-New-/250379226196?pt=Vintage_Car_Truck_Parts_Accessories&hash=item3a4bc3cc54 Most aftermarket kits feature similar pick-up sets & module plus uprated ignition coils (3ohms). Is it possible to do so in my stock distributor? If not which is the most reliable electronic ignition conversion for the above engine?

If i understand you correctly your question is if it's possible to put an electronic unit in the housing of a contact point breaker ignition? The answer is no. Because the axle differs. The one with pointe has 4 round edges on the axle and the one for electronic breaker has sharp ones. You need to exchange the whole distributor unit. You need the electronic coil unit as well. When you have the whole complete set you cab exchange it without any problem. Hope this is the answer to your question.

Title: Re: 131 electronic ignition conversion Post by: fi131 on November 16, 2010, 03:17:10 PM So the problem is the axle,but can you clarify what exactly you mean by axle?... not the shaft that is inserted in the crankcase.
Otherwise i pressume that both electonic and point distributors are interchangeable. They share the same shaft and gear . Altough it seems rather difficult to source an electronic distributor and a coil in nowdays Any other reliable suggestions like the pertronix kit ,to change from contact to electronic ignition?

You just need a complete distributor housing.
