Sorry, but can you explain more on how VTEC engine gives results equivalent
to VANOS?

I copied and paste this from Acura's website:

"In the RS, LS and GS models the 1.8-liter engine produces 140 hp and 127
lbs-ft of torque and it features 4 valves per cylinder and dual overhead
camshafts.
The GS-R engine adds the Variable Valve Timing and Lift Electronic Control
(VTECT) system to the basic DOHC architecture. In this configuration, it
produces 170 hp and 128 lbs-ft of torque."

With identical engine, VTEC raises 30 HP on a 1.8L. If this was true with
VANOS, E36 325s would easily have an output close to 240 HP.
