Camry+Celica?, camry engine? Options

[monkeywrench]

Hi, I'm Lea (Lee-uh) a 17 year old girl, and car nut.

I'm going to be getting a Celica soon (possibly buying back my moms old one) for really cheap (just wait, I'll explain) and I don't care what's up with the engine, I'm going to pull one out of a junkyard and have it rebuilt. I read the topic about what engines will and won't fit. From that list I'm leaning toward the 3S-GTE, but id wondered about the engine from a. '04-'06 Camry (a 3MZ-FE V6). I don't know if this would fit in the engine bay, or if I would have to get a new transmission along with that. Or would I be better off finding a 3S-GTE? I want something more powerful than a 7A-FE or a 5S-GE.

I'm still learning and don't know much about interchangeable parts. Also, about how much would it be if I had a new transmission installed in a '94 ST coupe?

I just found out that the guy who has my mom's old ST doesn't want to sell it, so I've got a different idea. I know whatever I do, I want to either swap in a 3sgte or add a turbo/supercharger to whatever engine it has. I think if I were to add either 'charger to a stock Celica engine I would have to reprogram the computer (that's what dad told me), wouldn't I? If i were lucky enought to find a 3sgte, would I also have to reprogram the computer for that engine?

All the things I'm thinking of doing, I'm going to do over a long period of time so the cost isn't really driving my decsision. Which would be easier to do? I think I might be leaning towards adding to the engine the car already has, after I have it rebuilt, because after my old Camaro I don't trust the engine of a cheap car, but what do you more experienced people think?

And whatever trim of Celica I get, it will definately be a manual.
