I have a 1994 3.8 manual. The miles are sort of getting up there, and i'm just preparing myself. I was thinking of getting a remanufactured 3.8 from the same year, and swapping it in. How much work is this going to be? is there anything i should look out for, or anything else i should get with it?

instead of the same year, try to find one thats a 99-04, it will have split port heads and intake manifolds. apprimately 50hp gain.
I just did this in my '94 mustang, I blew my head gasket and decided to go with a brand new motor. The motor swap was simple but it is definantly a good idea to replace a lot of parts. Besides my engine parts i also replaced the radiator, water pump, as much hose as i could, and a couple sensors. If you can I would upgrade your motor, 94 motor only has 145hp stock. Just going with an original 94 mustang motor I spent over $2500 on the motor and all the parts i needed, that is not including labor since I did it myself.
If you want an idea of the changes that Ford has made over the years check this out. Ford has upgraded the block, cam, heads, crank, rods, pistons, and balance shafts since your block was made
If you go to a 99-04 motor, several changes will need to be made. You need to re-pin the computer and make sure the balance between the motor and flexplate are the same. IMRC's will need to be addressed if you get an '01+ motor as well as emissions for all......
It is a great idea to do this swap if you have the time and the money. If I owned a 1994 Mustang and was going to do ANY engine swap that was not the original 3.8 V6 I would drop a 5.0L into it since they were used in those cars and it wouldn't take much more work than swapping to a newer 3.8 V6.
Hi.
I have a 94 with a V6 that I considered replacing when it blew a head gasket. I decided to just rebuild the heads and replace the gaskets. I'm glad I did, it runs fine now with 100,000 miles on it.
In my opinion all the extra work and money for another year motor is not worth 50hp, after all your probably just driving it to work and around town.
If you want a go-fast car, buy a V8 Mustang.
Do you know anything about Mustangs??? Just because a car has a V8 in it does not mean it is fast... GT's are not fast in my book, neither are Cobra's. They both need work done to them to be fast.
Specific cars? As in stock cars from the factory?? Not too many... I consider a car "fast" when it can run mid 12's or lower consistently, not a fluke or something. "Fast" is relative, it depends on the person, to me mid 12's or better is fast. Their are cars from the factory who have good or amazing engines in them that can become extremely fast but not to many fast cars stock. Just my opinion of course.
I judge cars by real world or trans am track performance more than 1/4 mile times. I like the 289 Cobras, Panteras, GT40s, 65-67 Stingrays, and Countachs for earliers cars. My favorite later model is the 96 Cobra. It's well balanced on weight distribution, hp, and handling.
3.8 to 3.8 swap...
