Why is the 3s better than the 5s? Options

[homebuilder]

I am considering an engine swap. I see the 3sge and the 3sgte are both more powerful than the 5s. I can understand the turbo one being faster, but why is the 3sge?

I was reading where the 5s was basically a newer improved version of the 3s, but it looks like it is not as fast, is anything about it better?


I have the 5sfe now with a manual. I value reliability, low maintenance and fuel efficiency. Power is great but not the main deciding factor.

Thoughts?

In addition to everything Edy said, the 3S-GE is also a high-compression engine and revs higher than the 5S. As he said, the biggest difference is in the head- the GE head simply outflows the FE head, helping the engine breath better, more air = more power. The 3S-GTE is lower compression but was built for boost and boost always = MOAR POWARRRRRRRRR!!!!!!!!!11!!1!!!!one11!!!!!elevenoneone111!!!exclamationpoint!!!! Also, the number in the engine name denotes the revision to the block, but there are also revisions in each engine- meaning a first generation 3S-GTE, second generation 3S-GTE, 3rd generation 3S-GTE, and 4th generation 3S-GTE. It's the 3rd revision of the S block, with different generations of each revision. It gets pretty in-depth, but not that hard to follow once you catch the trend.
