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 |

info regarding ST205 thick or thin block
Would like to see more truth/evidence in using blacktop blocks with 3rd gen 3sgte heads, as I looked back at your blacktop head you posted ages ago and compared it to a 3rd gen 3sgte block, and almost looks like there was a bit of difference between them (disregarding the vvti line), but could have been the angle etc of the pictures too. Actually from what I've read & understand the Blacktop 3S-GE's vvti operates up to 6000rpm, which does make sense. I have a diagram, that shows the different points of vvti usage in the dual vvti.  We do have these specs in our 3S-GE/BEAMS thread 4 Gen BEAMS Redtop 3S-GE IN: 256deg, 10.5mm lift EX: 244deg, 9.2mm lift Thats the advertised duration, which doesn't mean too much. you need the accurate way of camshaft measurement which is the '###degrees @ .050" '. I'm sure you have the specs edophus? No the BEAMS has a narrower valve angle,which I cant seem to find, but ours is 44.5° -------------------- |

I dont have those cam specs, the only person i can think of who might have that is g.booth. Also i'm sure the beams engines use high impedence injectors, same as the zz engines. I think its worth noting that it seems to be a waste of money going for expensive aftermarket cambelts or head gaskets with the beams, the oem ones are very good items, both the one i linked above and the ~300bhp na engines g.booth builds use oem beams headgaskets and belts.
