EFI conversion on 18RGU- what dizzy?What ignitor? what injectors?

As everyone knows i'm converting to EFI, and i have almost everything to convert. What dizzy will i need? I'm going to run Haltech computer eventually, but at the moment i got a 3TGTEU computer for intitial use. Should i go for coils? or just convert dizzy or something? Ideas???
Also what ignitor would be good to use? Would one off a 22RE motor or something be useful?
I'm gunna get RX-7 550cc injectors, what type do i get??
would these ones be ok? :

Sould i go for low impedance or high impedance injectors?
Any info would be appreciated!
Thanks
Ben

I would use the following
Coil get from a 87 magna, ignitor from the same.
Convert or get a 18rg electronic ignition.
If you can't find an 18rgeu rip the sensor and tone wheel from any elec dizy that has a similar shaft diameter to yours and graft them in taking consideration of when the tone wheel lines up with the sensor and when the rotor lines up with the dizzy cap electrode and around a 1mm-2mm gap between tone wheel and sensor.
If you are using the 3tgteu computer you want high impedence injectors the ones you suggest are I think? if not get some ballst resitors on them. You may be able to get it running resonable with this setup but tunability of the air flow meter is limiting especially with large injectors and idle quality.

OR get a 22R-E coil, ignitor and dizzy. Much less fiddling about. You shouldn't have any probs finding one either.

I'm not too familiar with the details, but I do remember hearing something about putting the insides of the 22R dizzy into the 18R-G points dizzy. Can't be sure though. It's a common mod in the US and I do remember that however it's done, it's bloody easy. Just pick one up and you should be able to figure out how it'll work.

I've got a 22R-E coil and ignitor on my car (2TGEU).. No problems at all... Nearly bolts straight in..
Get the electronic distributor from the 18R-GEU if you can.. Or you can get electronic conversion kits..

i'm aiming to have EFI in and running within 2 weeks with a 3TGTEU computer and loom. Keeping in mind that Haltech will be my final computer(when i get enough money), what set-up should i run to start with so i dont have to change anything when i convert computers?
Thanks peoples appreciated.
Ben
PS- remember this is all the setting up of a turbo 18RGU- EFI motor, so take the turbo factor into account.

I have been advised to use the 22R-E gear (coil, ignitor & AFM) as it supposedly bolts straight up and have the same pin-outs as the RGeu.
What fuel system are u running atm or plan to run? Those series 5 injectors sound like theyre thirsty little buggers.. Do they fit straight into the 18RG efi injector rail?
Does the haltech EMS u want to use utilise an AFM or map/maf/o2 sensors etc? what about the 3t-gte unit?
SORRY:Why use 87 magna items in particular? i know u probably have experience with them but what specific reasons make theses parts perfect for an 18RG/eu? thanks i just am in the process of sourcing parts such as these for my project, and im open to all options. I still think ill go with the corona 22Re gear cos it shouldnt need much alteration from what ive heard..
PEACE

I was told the injectors fit in the rail perfectly, but u need to splice the wires up as they have different connector points. I was planning to run a holley red pump to a surge tank then run a VL turbo pump to the fuel rail.

OK. Now i'm really confused!
Should i go for coil packs, or should i use a EU dizzy, or a 3TGTEU dizzy, or a 22RE, etc...
What should i run? I dont really want to put something in and pay some hard earned $$$ if i'm only gunna take it out again when i get a new computer?
Is a haltech the best option for me? I just heard that they were really good, but would it suit my predicament?
Basically i'm asking what i should use so that i can put it in and run turbo (eventually) without having to pay for something that i'm not gunna need. Hope that makes sense.
Thanks
Ben

Ben,
Sorry to confuse you. I would run the 22re dizzy if you can get it for say $40 any more and you should convert the 18rg dizzy. Get the coil and ignitor from a 22re or a magna should cost you no more than $20 from pick a part. We you run a turbo don't conect the vacum advance up. You won't get the best ignition curve from this setup but if you have to chuck it all for the haltech your only throwing $60 or so. You can run your haltech on this dizzy when you do convert just lock the dizzy up. and if you wanted to upgrade to DFI/wasted spark you can do this later on. This is what I would do.
Roger
