well, lets deal with the second part first...
As this is entirley possible. However, you need a compatible gearbox, as well as a complete clutch assembly, servo etc...
It would be quite expensive to do.
As for the former, well yes, theoretically, you could, but you would need to replace a majority of the running gear - dont forget you would need to cut a new transmission tunnel underneath the car - and as part of the process would need a whole new gearbox, you could do this as well, but it would cost you a lot of money.
Fensport have built a 4WD 3s-GTE powered Corrola that has hit 200mph...
I personally dont think its worth the investment, when you could buy a Celica GT4 for the money the gearbox change alone would cost..
