look at the front of your engine block. now at the top of the exhaust manifold/ header. then left about 4 inches and down about 8. there will be a flat square with an letter and number combination stamped in that square. google from there

should be a D16Y5

yes it has VTEC.... but it is VTEC-E

It is a version of SOHC VTEC, which was used to increase efficiency at low RPM. At low RPM, one of the two intake valves is only allowed to open a very small amount, increasing the fuel/air atomization in the cylinder and thus allowing a leaner mixture to be used. As the engine's speed increases, both valves are needed to supply sufficient mixture. A sliding pin, which is pressured by oil, as in the regular VTEC, is used to connect both valves together and allows the full opening of the second valve.
