I bought a 98 honda civic ex and the owner
changed the d18y8 motor with a d18y7 motor does
that make any difference??
are you sure it is d18?? these are known D series engines..
but overall not much difference either way..maybe just assembly plant is different..
Does vtec make a difference??
VTEC (Variable Valve Timing and Lift Electronic Control) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine. The VTEC system uses two camshaft profiles and hydraulically selects between profiles.
