i was considering switching from the stock efi on my 88 gt to a carb setup. Aside from the obvious new parts that i would need( intake, carb, throttle linkage), i was wondering if anyone else could think of any bugs that i might run into. I was also wondering if just using an adjustable fuel regulator to turn the psi down to like 8 or so would work. Someone told me that this would blow the electric pump.

Don't know WHY you would ever do that though.



Fuel injection gives more power, more tuning ability, and better gas milage.

i dont agree on the tuning abilty. with a carb you can set up primary and secondary jetting. plus by losing the gay efi intake, i would have the abilty to remove my valve covers without pulling off the entire upper intake. and as for gas mileage, i could not honestly care either way. the way i drive, bad gas mileage is always the result.

Think about it though. You gotta mess for HOURS on end screwing with vacumes and everything, changing jets, ect., all based off of the a/f and power.



With EFI, you just hit a couple numbers, and it's prefect. Set for any type of load, rpm, fuel, pulse width. It's a lot easier.



If the upper intake's getting in the way, here's an idea. Go flip through Hot Rod mag. There's a red 66 (?) Mustang with a twin turbo 302 under the hood. Check out the manifold design there, and modify it for your needs.

I get 26 miles a gallon with just a spring swap and it takes me about 1-2 mins two unscrew 2 screws and replce a spring and put another one in and rescrew it back in. I think that is pretty dang easy.</P>

JEEP are you running a carbed setup?You running an EFI setup?Hell are you even running a stang?Then how and what do you know about them?</P>


To swap over to a carb and its a great idea to you need the intake,carb,and distributor.You can either go with a points setup that i dont recommend or you can use the DURASPARK 2 setup which consists of 4 wires and a small littlebrain box andyoure on your way.</P>


Carbs do offer more tuning capabilities and their cheap to fix,tune,and maintain.Not too mention if tuned right and by right i mean specigically for either performance or economy a carb is comparable to efi.</P>


Go for it a carbed setup rocks!I love carbs and wouldnt have it any other way.</P><edited><editID>TheGmKiller331</editID><editDate>37997.9190856482</editDate></edited>

Carbs are easier and cheaper to tune.

EFI is far more complex, will ultimately yield either better economy or better power than a carb setup will, and do it more efficiently.

Basically you'd only notice the difference if you were super **** and spent months working on the EFI tune.

Carbs are more ideal for John Q Public to work on, whereas it's not all that costly for a manufacturer to tune the EFI.

i live in cali, and i got the efi setup on my 88, if i went to carb, i wouldnt be smog leagle would i?

you could make it pass the sniffer, but I doubt they'd much like it on a visual

one leave the real questions ot ppl who actually know what there talking about.

as far as the carb setup go with what socalledkilla331 has to say. <img border="0" src=smileys/smiley4.gif border="0">. you will need a regulator for the carb so you dont feed to much fuel to the carb. a carb i think has around 6 psi. a efi setup has around 37 stock. youll destroy that carb with that much pressure. you should be alright with the switch as far as problems go. but please leave the wiring in the car. you never know if you sell it if someone will want the efi setup or you might want the efi setup again.
