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)

Variable Length Intake Manifold (with info regarding ACIS and turbo) Actually the ST162 1st Gen 3S-GE had TVIS, did you mean to write ST215 intake manifold by chance? I guess would be up to personal preference which either intake manifold you use... but maybe not one of the TVIS manifolds



Can't swap a blacktop 3SGE into a ST20# engine bay, due to a lot of reasons and costs. You also cant mix BEAMS blocks/heads with a 3SGE or 3SGTE, due to a different cast

Hondas
VTEC - Varies duration, timing and lift by switching between two different sets of cam lobes.
i-VTEC — In high-output DOHC 4 cylinder engines, the i-VTEC system adds continuous intake cam phasing (timing) to traditional VTEC.

Toyota
VVT-i - Continuously varies the timing of the intake camshaft, or both the intake and exhaust camshafts (depending on application).
VVTL-i — Continuously varies the timing of the intake valves. Varies duration, timing and lift of the intake and exhaust valves by switching between two different sets of cam lobes.

Nissan
N-VCT - Continuously varies the timing of the intake camshaft, or both the intake and exhaust camshafts (depending on application).
VVL — Varies timing, duration, and lift of the intake and exhaust valves by using two different sets of cam lobes.

(I'm going to create a NEW sticky which will have this & more info for easier reference)

as I posted before

Slightly offtopic, but Tom's Racing did a "280T" Altezza, it was turbo and limited to just 100. Also the altezza's blacktop 3S-GE has alot of readily available turbo kits from Trust/Greddy, biltz and I think even HKS do one aswell. Plus all the cheap knock offs.
