If im not mistaken , this can seen on the engine cover of the
car... Big VTEC is normally written bigger than DOHC on the cover
meanwhile small VTEC is written smaller which is smaller than DOHC
writings on the cover. Big VTEC is normally b16b engine and second
generation b16a engine. In addition, other engine such as h22a
which can be found in honda accord 1995 and also prelude is big
VTEC. Small VTEC is first generation of b16a engine and others. The
VTEC engages at the certain rpm and varies for different model of
engines. For example b16a big VTEC's swithover is at 5600 rpm where
the valves engages. Small VTEC is underpowered compared to big VTEC
and is almost can't be felt when VTEC engages. Big VTEC is very
powerful, the VTEC engagement has a turbo like feel and it has
160hp or more, depends on the car. As mentioned above, the b16a
