EFI or Carb??

IMHO- going to a carb setup from EFI is REALY not the thing to do if its going to be any kind of street car.

EFI (even our red headed step child of an eec) is realy not that hard to work with and you will get tons better mpg, smog will be pass-able, better throt. response (in general). Yes it may cost you 500-ish$ to get the eec properly tuned or to get a tuner and spend some time learning.

Carb's- well they are better suited for track cars and can be driven on the street. You will have a big PITFA if you need to pass a smog test. MPG will nto be as good as EFI. The cost may look like it will be cheaper to just go carb but sit down and to do it right with good parts will cost more than getting a tune. An ex. carb intake, demon or holly carb, dizzy, re-wire, fuel system from the high press efi to low press. carb stuff. It will nickle and dime you way past the point of just getting things sorted out now.

P.S. What is your problem with the car now as far as tune and issues that makes you think the swap would be better? I am trying to see if there is a way for the great amount of help here to get your setup working properly.

Get a tweecer and be done with it. no need to go carb. talk about no resale value.

I'm a dinosaur. I cut my teeth on cars when fuel injection was exotic, mechanical, and expensive race car stuff. I'm in the process of doing a efi to carb swap on a '92 F-150. However, I would not convert my 'Stang over to carb without a really good reason. I agree with blksn955.0 and therian that you are better off fixing the relatively minor computer problems with your car as it sits than switching to a carb. Think about it--you would need to get a carb, manifold, gaskets, new distributor with mechanical/vacuum advance, throttle bracket, throttle cable, fuel line and fittings, fuel pressure regulator and possibly a low pressure fuel pump. If you have an AODE you need a transmission controller like a Baumanator. I can see a minimum $1000-$1500 right there depending on how much you can buy used. In addition, you're going to have considerable time and aggravation in getting it all hooked up and working properly. With that kind of investment you could ship your car somewhere and have it tuned.

For the self tuner route you have quite a few choices.

TweecerR/T- dont waste your time with the base model you NEED the datalogger that comes with the R/T to know what your changes are doing--$550

PMS- alot easier as far as user friendly-ness--I think its about $650-750-ish???

SCT pro-tuning software- Higher end newer unit that has dealer support cost ???? I heard 800$ or so but I dont know.

We have a tuning section, I would search each tuner out by name and see what you think and ask questions there.
