3SGE and 3SGTE 3rd gen Diffrences Options

[Alan]

Hey guys its me I am back in the game hehe, I need some info with anyone who can help me out I need to know the main diffrences between the 3SGE and 3SGTE 3rd gen cylinder heads, I need to know what valve cover fits the 3SGE and if a fuel rail of a 3sgte will fit a 3sge head any other diffrence anyone knows please le me no

the 3s-ge was designed to make its peak power at 7000 while the 3s-gte is designed to make its peak power at 6000.

there are so many factors you need to take into consideration besides the theoretical output figure. you may find you sacrifice far too much and are better off having an experienced engine builder order some custom cams to account for all specifications.

examples are,
valve overlap (better for NA, not so good for turbo)
turbo size?
rev limiter increase?
engine durability?
low end response?
gearing (what will you do if you lose low end response on a long ratio gearbox like the E153 and E154F? Or will you stay with the S54?)

The 3SGE only makes its peak power at 7000 because variable valve timing introduces a broader torque curve that positively affects low rpm drivability / cylinder filling sufficiently enough to allow for a broader total RPM operating range.

valve overlap being better for NA and not turbo is not the whole picture. VVT changes the rules in valve overlap environment allowing you to have the best of both worlds. AFAIK valve overlap is a good thing at high rpm in turbo cars as well.

rev limit is a function of engine component specs and really nothing else. Meaning the components used in the build and their specs/configuration/installation will ultimately decide the engine's rev capability limitations.

Engine durability follows a similar thought process. It should be interesting trying to uncover whether the 3SGE or 3SGTE is ultimately engineered with the better potential for high power durability.

For low end response you simply cannot argue with the 3SGE being the winner. Variable Valve timing beats Static cam settings no matter how you implement them. Yet another significant consideration towards the possibility that the 3SGE may be the better platform.

Like i suggested before I really like this topic!
