12a convert to FI?
Hello, ive been looking at doing an efi on my 12a, the problem is it has limited options for timing with the distributor. Is it possible with a billet adapter to get the injectors, and a crank sensor from fc or other crank sensor setup to convert to a standalone ecu , And what would i need to complete it, Air sensors, o2 sensor, ect? this would be huge compared to efi and would probably cost almost the same. pleees help

the FC CAS will drop right in, and then you can run whatever coils etc you want

The distributor post CAS is easy option, you can also buy crank trigger kits from more than one supplier from memory. IDA style injection throttle bodies or adapter plates to suit layer 13b injection manifolds.

as mentioned above, ignition will be fairly simple to setup. Gen 2 CAS directly replaces the dizzy. then choose a compatible coil setup. when you get your stand-alone, the wiring diagram will tell you what you need (what it wants to see), but suffice it to say, you will need a minimum of: O2, throttle position, water temp, and air temp. those are basic. things like MAP, MAF, idle air, etc. they may or may not be necessary for the unit you choose.
you're going to have to give some serious thought to what intake setup you plan to run. if i recall from one of your other threads, you mentioned you also plan to turbocharge, so you need to work that out. the easy routes will be the things that you can still get manifolds for, that way you can bolt them to the engine and just worry about fabricating plumbing - as opposed to fabricating an adapter, and/or a manifold AND plumbing. the problems with those routes are ... injectors. where will you put them?
your next most intense (in terms of fabrication) area will be the fuel system. you will need to make your fuel supply EFI-friendly - either the tank needs to be modified or you'll need some sort of surge tank situation.

i have no idea if 20 oz is adequate or not. to my untrained/uneducated senses, it doesn't sound like enough - but the bottomline is that i don't know.
for the lift pump, i know it doesn't have to be anything crazy, just something that can supply a good volume.

I've been thinking, i dont think a surge tank will be required, the most the car is going to see is stop sign pulls, and going around corners at 50. Most the time its going to be normal road driving, so if i keep the tank nice and full when im doing fun stuff i should be fine
