Is a coil usable between different engines?18Rc->18Rgeu

Hey, i had my coil and dizzy lead give up the ghost tonite and need a new replacement coil & lead. This was pretty annoying as i need to buy a new coil & all leads for the 18RGeu in the next few weeks but now i need one just to keep the 18Rc running.. What a Hassle! Firstly:
Is there any coil that i can buy which will run in the 18R-c with points dizzy for a couple more weeks, then be used in the 18R-Geu which has standard elec. dizzy and efi? I have been told to get a 22R-e coil and ignitor for the new setup(18RG), but now i need one just to get the ra28 around and dont wana buy a coil that i'l be ditching soon when the car goes off the road. Are they multi-purposed? or is there a model which can be used in carby AND efi setups, etc.? or do they differ in signals or charges or anything which would hinder their use with the differing types of dizzys etc?
The RAA dude said it doesnt matter and "..a coil is just a coil.." but i dont trust an old dude even if he did get my car running again to get it home, i hadnt given him much info on what i had planned with the motor swap.
Anyone who could offer any help or advice on parts would be greatly appreciated!! its just i need a good coil for the efi RG but i need to get the 18Rc running again if it was possible at all without buying 2 separate coils? if not i guess i'll have to get it towed around haha which would suck seeing it has a beauty of a single-cam 2 litre under the hood.
Thanks again
Guy

heya guy, im pretty sure that you can use the same coil between then, my mate had a 2t, now he has a 2tgeu and he is still running the same coil setup.

Hey, cheers justin mate. Yeh thats what i thought, but now different people have been telling me different stories, it depends on the details of the electric dizzy internals... I think?? because the 18Rc has a points dizzy(oldskool) and the 18Rgeu has elec dizzy, but there can be different types of these electric dizzys.. therefore need to know the exact type of dizzy internals to know what coil and ignitor setup i need for the 18Rgeu!?!
And nowhere except Sleeka Spares seems to stock aftermarket coils for the 22R-E even, and they all told me to find one at wreckers which i will do. I didnt think the 22R-E was an imported motor? spewin, ohwell good old sleeka spares should hook me up with a second hand coil for the 18Rc beast, so at least il be able to get around to sleeka spares again to get more stuff for the next phase.
I think maybe how your mate used the same coil for 2t -> 2tgeu is because (correct me if im wrong) the 2tgeu is still using same dizzy? just a guess. but the dizzy on a 18rc differs greatly to the 18Rgeu i know that.
Do standard 2tgeu come with similar dizzys to standard 18Rgeu?
hmm well its all good, just gotta go investigate my dizzy some more ..
Thanks Again for your advice

Guy,
From my experience yes a car will run with a point coil on an electronic ignition and vise versa. When I put a points coil on my electronic dizzy it ran like s$%t. Some may run ok. You are not talking about a dizzy to coil mismatch, with interchanging between different electronic distributor coils you are talking about a mismatch between ignition modules and coils as these should be match.
I have however found little to no problem in using an electronic coil on a points car did this along time ago but from memory it seemed to work fine. I belive and I could be wrong coils found on electronic dizzy use a weeker signal to break down the primiary coil in a coil. Therfore when you put the point coil on an electronic ignition the signal is often not strong enough to break down the coil and the engine will miss at higher rpms. But it works ok the other way.
So use an electronic coil on the points and you should be fine.

Thanks for that explanation roger, but its all good i eventually got a second hand one from sleeka spares for 10 bucks and bought a new $3.75 blue lead  , was the easiest option seeing as the 22R-e coil and ignitor is going to set me back $100 from a parts place so i dont wana risk it, as the new one just bolts in straight where the old one was and wires up all the same.. Seems to run heaps better so thats good too for $13.75
I recall on another thread Roger you mentioned the use of 87 magna coil& ignitor on an 18rgeu, does this setup require any alteration of the wiring or plugs for an 18rgeu electric dizzy with factory computer? because if they are a cheaper option (compared to imported 22R-e parts) i may use these magna items as they should be a heap less costly from wreckers, am i right?
Anyway thanks heaps for the help..
guy
