Ok so i wanna possibly put 45's on my xe, (i've sriously considered tb's, but they're not old skool enough for the car) and would prefer it to run electronic ignition if at all possible. As i currently run a dis xe, to run a dizzy i'd have to change the exhaust cam, and find that elusive cav item, so i'd prefer to keep the dis if poss. Is this the sort of thing i could possibly do diy? If so where can i buy the right stuff to do it? I've seen the mbe stuff and it's quite neat, but also pricey iirc. Would it be worth spending the extra on it?
What will i actually need? a tps switch to fit on the end of the carb spindle, crank sensor, (i presume i can keep my existing xe crank sensor?) and some way of distributing the spark (can i keep my xe coil pack?) as well as the box/ecu. Anything else? cts? I'm not too bothered about building it myslf as i'm quite handy with the old soldering iron;) . (in fact, sod that, fancy building me a loom stu Lol)
I'm only considering this as i have been offered a set of reasonable carbs, but would need an inlet too. I'd also possibly have to remove the bulkhead too, but not to bothered about that as i can have that as a "free" by doing it myself.

Any helpful advice, input greatly appreciated. :thumb:

mega jolt is very cheap but needs a ford system, mega squirt is still very cheap but can be used if you ever switch to tbs check them out, if your handy with a solderng iron you can buy it in bits and put it together urself!

er i'd just prefer it tbh. (plus i can't be assed to find a dizzy drive exhaust cam, then swap it, then find suitable "reliable" cav dizzy etc etc 'cos i'm lazy:) ) For the price of a dizzy off e-bay i could probably build an elec ignition set up i reckon. (i hope Lol) Plus the ignition timing would be that little bit more precise/reliable. Plus i think it looks just that bit neater too.

The old cav dizzy setup is the easiest and cheapest option.
Depends how much you fancy spending on the ignition management. Cheapest is megajolt but you cant use the gm dispak etc, needs be old Ford stuff.

Would be sweet with 45s on, keeping in with the car's "theme"
Dont forget to budget for stuff like fuel pump/regs too.

What pump/tank set up would you recommend ad? It currently has a v6 vectra pump in spi tank for the standard xe set up. What fuel pressure is needed for 45's? Whats the price difference between say megajolt and the mbe stuff? anyone priced it up before?

You'd need a low pressure pump, 4-5 psi, a filter king.
MJ costs are about ?150, MBE/Webber Alpha/Emerald all start at about ?500.
Don't know about spi fuel tank, but I would hazard a guess and say it should do.

Whats the price difference between say megajolt and the mbe stuff? anyone priced it up before? You could keep the standard mpi pump(wired to a switch), and get a high pressure regulator to drop the presssure to about 10psi, and then you'll need a carb pressure regulator to drop the pressure down to 3/4psi before the carbs.
Or remove the pump, and just have a normal low pressure pump(Facet etc) with a single pressure regulator before the carbs.

Megajolt is ?100 fullybuilt, but you then need a loom and ford edis ignition setup.
Any other ignition management is much more expensive.
Tho its more "professional", and there are more people that are used to mapping mbe etc etc.
Depends how much you fancy spending on the ignition side of things.

A re-weighted cav dizzy works fine, and its pretty cheap, i think thats what Nj uses on his. And it keeps in with the old skool look,Lol.
