Why can't we turbocharge a 3s-ge?, Compression ratio related Options

[dudeofchaos]

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)

cant really read anything into those power figures, who knows at what point the cams might need to be changed for more power, and anyway you can still get vvti cams from toda and trd if you want, you'd want a non vvti cam for the exhaust side anyway and there is quite a lot of choice there, less so for the intake side with vvti but still toda do a 268 and trd a 282 duration cam or you could go with a cam from mr booth i'm pretty sure he just gets trd or toda cams and puts his own grind on them anyway.

If your at the power levels the beams cam becomes a restriction i think getting the right cam grind is probably not going to be that big a deal in the grand scheme of things.

not really convinced about the idea of going with 2jz pistons either unless it works out mega cheap, would rather go with custom forged pistons from the likes of JE, which isnt too different in price to forged 3s-gte pistons from the quotes i had, or arias have a part number i'm sure for forged beams pistons, by the time you've payed for the machining work on the 2jz pistons and rods it might not be any different. If your feeling flush also g.booth can supply them or you could use toda pistons.
