"detuned" Si engine?

not sure, but my guess is if you get a RSX inner valve springs ant up the cut off to 8000 RPM.. you should get more HP with I/H/E

My understanding is that the RSX (base) and the Si engines are very close to the same thing, but the Acura tuning brings the HP up just a bit. These are VTEC on intake only.

The RSX-S mill is VTEC on intake and exhaust, hence the greater power.

I've read this in multiple articles and reports, so I assume that it's the right info.

I mean the RSX type S valve springs

yeah, the valves spring and the Si's only "partially" open @ 5000 and @ 5500 the open all the way from what I read in the tech corner @ Temple of Vtec?? The only thing that I don't understand is why they didn't make the Pistons to where they would handle the 8000 redline w/o shaddering the rods, again this is something that I read but the base model RSX engine is the exact same as the Si so it is really detuned too huh.
