Youre asking a bunch of boyracers. Dont expect to get a straight answer where theres a comparison between performance of engines!
My first Celica was a 3SFE. I've since had a 3SGTE and a 3SGE and I can tell you now that the 3SFE isnt as bad as people say it is.
Its the 'Economy' Head. Thats what the F means. Yes, its lower HP. Torque wise its lower, but not as significantly.
Its a very fuel efficient engine. You wont get the same economy in a 3SGE nomatter how gently you treat it.
OTOH you can use the revs of a 3SFE and it'll deliver realistically. Its not a performance engine. So it depends on what you want to do with it.
My el-budget Celica (purchased before I knew much about them) with its 3SFE did me well for 2 years and was sold because it was getting old, not for any other significant reason. Theyre bulletproof, pretty much, though the 3SGE is comparable. If you are worried about horsepower, get the 3SGE but dont let horsepower alone govern your choice.
Among other things the 3SFE is probably gonna be more common in the Curren. See more 3SGE's in Celicas. So weigh all the options when purchasing, and give engine some value, but dont let TS bias you too far
