5sge?, 20v ge head on a 5s block Options

[ILoveMySilly97]

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.

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)
