6G Celicas Forums

Has it been done? I was reading and looking at other 5sge with the 3sge heads. I know that's been done several times. It got me thinking even more if anyone has done a head swap with the 20v 4age head? Sounds like it'll be able to put out really good power if done right.

5S-FE
4A-GE

What do you think?

isn't the block called 5s and 4a? The heads are fe and ge?

this topic has been kinda covered. the 5s (2.2L) block has been paired with the gte head (from the 3sgte) before. the 2.2L block gives the setup more torque with the larger displacement. "ge" heads are toyotas answer to performance ie- 2jz-gte, 1jzgte, 7mgte, 3sgte. the "fe" heads such as 5sfe, 7afe, 2gr-fe are more plain jane setups. do some reseach in the sticky sections of each of the forums. its good info!

Short answer is no.

Long answer is most Toyota engines can only share some of the components between each other as long as they're from the same family of engines. Think of it as sharing your car with your brother, vs sharing it with a complete and total stranger.

So for example, 3S-GE, 3S-GTE, and 5S-FE can share some of their components between each other.

4A-FE, 4A-GE, 4A-GZE, 7A-FE can share some of their components between each other too.

Most people with an economy (FE at the end instead of GE) engine mostly swap high performance GE heads into their otherwise economy engine. Two examples are the 7A-GE and the 5S-GE(most of the time for turbo)

Another example of possible sharing is that you can interchange camshafts between a 3S-FE and a 5S-FE, and you can interchange cams from some generations of 3S-GE into 3S-GTE heads (some cases this is an upgrade because the naturally aspirated engine uses more aggressive cams to ramp up output power vs the GTE using the turbo to do so)

BTW FYI: F stands for narrow-angle head, and G stands for wide-angle head. (22.5 in the case of the 5S-FE and I believe 44.5? in the 3S-GTE head) The angle on the valves is important for good flow to be had.

P.S. We were all once pretty inexperienced and "dumb" when it came to engines... don't act like you were born with that knowledge lol.

I know they're been 5sge fron 3sge heads but I'm talking about the ge heads from the 4age.



So the ge heads from the 3sge and 20v 4age isn't interchangeable? Which concludes that the ge head from the 20v 4age isn't interchangeable with the 5sfe since the 20v ge head isn't interchangeable with the 3sge? Lol. I never gutted out or went inside an engine before so I don't know anything about engines but the basic stuff like engine accessories.

Yes. What you're confusing is that the GE heads aren't the same because they're GE. The only thing they have in common is that they're wide-angle heads with some technological advances (in some cases, like for examble ACIS, VVT-i [Beams]) .


Even though the 3S-GE and 4A-GE both have GE heads, the head also belongs to the family of S-engines and A-engines respectively. GE and FE heads aren't two families where all GE and FE heads fall into together. The heads are tied to their family of engines as well. the G is just an indicator of performance-oriented head, not a family.

I see. So it's basically just the style of the heads then. Makes more sense now. Thanks.
