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 |

learn about dynamic compression guys, longer duration cams means lower dynamic compression, all else being equal, a higher duration cam can negate a higher compression ratio, in theory, you will shift the power band, but there is no good reason why a na 3s-ge engine cant make great power boosted, infact many make more power per psi, its just you have less tollerence to detonation. Research dynamic compression and ignore idiots is my advice, it isnt clear cut, but you will mostly hear parrots. given cam timing has an effect on dynamic compression, realise that vvti has a dynamic effect on cam timing, and therefore dynamic compression, and if you arent following by this point, probably shut up.

If there was ever any question as to whether or not what you said is true, i think someone would have to take a look at the dno comparisons of 3rd/2nd gen 3sgte's with the 3rd gen intake cam upgrade...you know, running a intake cam on both the intake and exhaust (cam areas) of the 2nd/3rd gen 3sgte.......yes the powerband will shift ( i think it was 200-300rpm to the right last time i saw) but hey its a freakin awesome experiance if you are already pushing your ct26c2 to the limits (imma start calling the ct20b the ct26c2 since that is what toyota has designated it)... -------------------- (\__/)
