EFI conversion.
What would i need to put EFI into a 1983 camaro that used to have a 305 that is now getting a 350. What PCM etc.. And also we most likely will be putting a turbo into this car.

Easy..
Go with a singleplane setup, 1,000cfm throttle body, turbonetics DUAL intake throttle body hat, '749 ECM out of a gmc cyclone, diy prom, and a set of ebay twin turbo headers
(about $300).
You'll need a harness out of a donor car, injectors, 2-bar map sensor, knock sensor, coolant sensor, etc.

How about a TPI set up? could you just take the PCM and TPI system out of a 92 and put it into the 83?
And with the EFI system if you were to put a twin-screw or roots style onto the 350 what harness/pcm would i need still the '749?

As far as a roots setup, if you search some threads by Saturn he did a twin eaton setup on his car before he gave it to a relative.
You can use a TPI or TBI harness for the '749, since you'll have to do some repinning either way. Even a native '749 harness won't work on a V8 without some splicing.
