I know that the 3s-ge engine has a higher compression ratio than the 3s-gte (which I guess means that the pistons' head are thiner right?), but what does it change so that we can't (or shall not) turbocharge the 3s-ge?
Is it because it would (I don't know) be too much compressed exhaust gases for the turbo to hold? BTW: what does the last number in the compression ratio mean? (Like in 10:3:1) This post has been edited by dudeofchaos: Jun 26, 2011 - 10:51 PM |

The 4th generation 3S-GE BEAMS has a higher compression than any other generation, so you have to be more careful boosting it. Just because it's difficult to boost doesn't mean it never gets boosted. However, the 3rd gen 3S-GE has lower compression and is a better candidate for boosting. But the 3S-GTE has stronger internals and was built for boost already, so if you want a 2 liter engine with boost on a budget, it's really the only way to go that makes sense.
