OK...



V8 3.5i ex rangie, which was almost certainly a "flapper" system.



If I get hold of the hotwire system, how much hassle to fit it to this engine? Or am I better off sticking to a flapper?



reason I want the hotwire is that it's less prone to damage from LPG backfires.


Same pump and fuel lines, just fit the complete hotwire inlet manifold, harness, ecu, air flowmeter etc etc. Make sure you get an ecu that has the correct fuel mapping, dunno if a 3.5 will run on a 3.9 map, never tried that one! You don't need to connect the gearbox neutral sensing wire or the roadspeed sensor, it'll run just fine without them. FWIW Austin, I ran my 110's 3.9 engine with a modified flapper system and never had any backfires - just make sure all the valves are lapped in to their seats correctly and that the ignition system is in top condition. (Use only genuine parts dizzy cap, rotor arm and leads, the aftermarket stuff is crap and no need to waste money on magnecors IMO!) Badger.

I don't know what if anything is available with it. If most of the flapper system is available, I'll probably go with that.

I found the biggest benefit of the magnecors was the much better quality plug caps and lead ends. The Lucas leads are almost certainly as good (or champion triple-silicone) in terms of the actual conductor and insulation. The magnecors had the best components I've seen. I had a set of Bosch leads on something, which went on fine but the first time I pulled a cap off it came off in 2 pieces. I binned them in disgust, and won't buy any more.
