Converting 2.8L to 5.0L

It's more work than you think. The suspension is different due to the weight difference between the two motors. You need to change the springs and struts. The differential needs to be checked to be sure it will handle the increased torque. The smaller motors often come with lighter weight differentials. The radiator is larger for the v8. The trans is probably not tough enough to stand up to the v8. And if you have to pass a smog test, putting a carb on will make it unpassable. Also about smog- you can upgrade to a newer year motor, but not to an older year motor, at least in Ca. Check that out before you change anything. Try alt.autos.fordmustang for more detailed info.

most 2brl carb will bolt to the tbi manifold, have a 84 lincoln in my 82 bird bolted right in

Its actually easier than you think, yes you could change the suspension,rear end tranny and all that, but you dont really have to. the rear in your car is a 7.5 inch rear, the mustang came with this rear even if it was a v8 till 1986/87 then went to the 8.8(unless it was a v6 after) 1993. The fours all came with 7.5s this will be strong enough to do the job.the most important thing to upgrade will be the front brakes as the 4 banger used a smaller disk and caliper. the suspension will do and be safe till you can get the right stuff from a GT or LX 5.0 if your car is a 5 speed you can still use the tranny but you will need a special sleeve as the splines dont work together between the imput shaft and tranny The 84 engine will be a CFI unit unless carbed from factory you will definately wanna ditch this. get a factory 4v intake and carb to keep it cheep, they are easy to score at a wrecking yard as for passing a E test it the car is tuned right and the carb set up you should not have a problem passing the test. just my .02

Hey no problem, I have owned about several mustangs in the past. and have found how easily these cars can be worked and reworked to get the results that are intended. I have helped a few friends do the conversion as well as have built the current stang that i own from just a shell. using parts from every imaginable source. lincolns capris other mustangs a ltd and some mazda/ranger parts its been by far the most fun project ive done yet! im on a really strict budget and kinda like using parts that dont really belong to a mustang. it has kinda improved the car in some ways. I call her the junkyard jem. kinda back from the dead. you cant really tell the difference by looking at it or sitting in it but the car is about half non mustang another good site is foureyedpride.com they are pretty helpfull as well
