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? rolleyes.gif rolleyes.gif

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.

Tell that new technology to theold pushrod in my rx7. Besides what's the new technology in the 5sfe??? It's about as basic as an engine can get. Hell even my crappy 3sge has variable intake runners, which the 5sfe has nothing like it.



It's not 'all in the tuning', it's all in elminating denotation which tuning has it's part in but only a part. Sure you could do it, you may even get away it with for a while... it's still a ****ty option if you're planning on going turbo. All it takes is some ****ty gas. I'd rather run a higher boost 3sgte, than a lower boost 3sge.
