3SGE vs 5SFE, Which is better? Options

[jackkasper]

I had an 86 GTS with the 3SGE engine and my son has a 96 Vert with the 5SFE. I want to say that the older one had 135 HP as does the newer one. Can anyone give me an informed description about whether the technology of the late engine is better? If you were going to replace the motor which one would you choose?

3sge is way way better than the 5sfe! the 3sge you already get more horesepower of course, and then you can turbo it. the 5sfe is well, the gt engine, and personally i would never turbo it, like everyone else says i would brather do a swap and put a 3sge in it. go to the engine and maintenance thread, and look at the read this stickies at the top, they have more information than what i am giving you as well. plus if you hafe a 5sfe, its easy to put the 3sge since they have the same mounts if im not mistaken

not necessarily, it depends what kind of 3sge cus those high compression ones need pistons still and some internal work while a good late model 5sfe in condition is just bolt on with its compression ratio. but one for one 3sge is supposed to have a better head while the 5sfe has a better block.

Not a good idea to turbo a 3sge. The 5sfe is a better option even though neither would be the best. 3sge has a high compression ratio.

I kinda agree with this with what ive been saying. it would cost more money to buy a 3sgte, rebuild it, and drop it in labor paid or not. While a good 5sfe is just bolt on application "for the most part or if you get like the tubes made already". Generally the rule is if your power visions are ~300hp or less=5sfe if its 300hp or more=3sgte. however a 3sge is a tough call cus you still got to do internal work, I would just turbo the 5s or just swap 3sgte.

both of you guys are dead wrong.

The 5S-FE is a much better engine that the 3S-FE. it is newer technology, has a longer stroke making more torque and it is very boost friendly.

the 3S-FE may have high compression but i doubt it higher than a 2ZZ and we boost those all day long. its all in the tuning.

OP mentioned 3sge but then again idk both motors existed during that time for the celica. but then again OP mentioned he had a 86 GTS, so I think it was intended for the 1st gen 3sge.

smaay you do know were comparing the 3sfe found in ss-I celica's when the TITLE CLEARLY STATES 3SGE vs 5SFE

i think thats just a misread on his part.
