fadedsun Posted August 8, 2015 Share Posted August 8, 2015 I'm in the process of converting my brdm from the original configuration to a Chevy big block, 366. The new engine is 12v. i know some other people have done conversions. How do you handle the voltage difference? Quote Link to comment Share on other sites More sharing options...

How do you handle the voltage difference? keep everything as it is and just change the voltage for the chevy big block, assuming it is petrol that only means a 12 volt feed for the starter and ignition system, you could do a wholly independent loom for the two and keep it away from any of the 24 volt systems...the alternator I am sure you can adapt to be 24 volt and run a 12 volt feed to keep the 12volt starter and ignition alive...

FW200 Posted August 11, 2015 Share Posted August 11, 2015 The ignition on the BRDM is actually 12v I think.. Why are you changing the block btw? Quote Link to comment Share on other sites More sharing options...
paulob1 Posted August 14, 2015 Share Posted August 14, 2015 for more power I reckon, the gaz unit is only about 120 or 130 bhp cant remember exactly...not massively powerful but basically enough... Quote Link to comment Share on other sites More sharing options...
Walis Posted October 15, 2015 Share Posted October 15, 2015 140hp 357Nm. Ignition in BRDM is 12v. Starter is 24v. http://www.fotosik.pl/zdjecie/e775adc43a5f624e Quote Link to comment Share on other sites More sharing options...
Starfire Posted October 16, 2015 Share Posted October 16, 2015 I'd assume that you would be keeping the 24V starter, so there shouldn't be any problems with the conversion and no need to switch it out. About the only thing you'd need to do is adapt the 24v generator/alternator to fit on the Chev. Or, you could just keep the stock engine... For the most part, engine conversions always take twice as long and cost twice as much as expected, at least, and are often rarely worth the effort. While I do like modifying cars, when it comes to MVs, I think that originality is important too. Cheers, Terry Quote Link to comment Share on other sites More sharing options...
g0ozs Posted October 16, 2015 Share Posted October 16, 2015 Having acquired a half finished engine, generator and 24V to 12V conversion in my "diesel" SUMB the biggest challenge has been the instruments which were of course designed for 24V operation - replacing lights is much easier !
