AF.com is another forum I frequent, specifically the '88-'91 Honda Civic/CRX sub-forum.

As far as the helm manual, it differs slightly, in my experience, from the Honda FSM, in that the helm manual tends to provide more walkthrough type information, versus the FSM which normally just provides the actual data one would need to diagnose or service the vehicle without the actual step-by-step direction one may need.

I personally prefer the Helm for most procedures, but use the FSM as well.

IMO, without further information, I'm guessing the iVtec setup the R18 uses is exactly the opposite of the normal Vtec system, in that it is designed to make less power. The normal Vtec system was designed to have a second profile that would aid in making power above the standard RPM range of a standard cam design.
