well, bud...that last link is the closes thing you want...2.2 liter engine..the standard 4 cylinder engin for the camrys from year 93 to 96 *yes....for the others...gen 4 also.
not so sure what they mean by 3sfe and 5sfe...they are defintely TWO DIFFERENT engines
the
3sfe is for camries earlier than 93 and are 2.0 liters
the
5sfe is for the years 93 up and are 2.2 liters.
you should get some clarification on it when they say they "call it" a 3sfe when it's actually a 5sfe.
the v6s are pretty expensive but you have more opportunities to mod them
since you said you might want to mod it later down the road...maybe you just might want to check out the junk yard....at least to get a look at what you might want on line if not for anything else
