I am having problems with my 94 Integra VTI-R(SIR in Japan). It's the one with the 4 round headlights and running the B18C engine. My problem now is, when the RPM reaches 5800 (vtec engagement point), I cant hear the VTEC roar at all. It's hardly noticeable...... I believe that the vtec did kick in becoz i was revving the car slowly and felt that the car was trying hard to gain power at around 5000 rpm but I can feel the car picking up power at 6000 rpm again. Currently, I have installed the Apex'i SAFC, Apex'i ITC, Apex'i cat back exhaust, Apex'i air intake but I doubt this is the problem. Can anyone tell me why doesn't the engine roar at all when the VTEC kicks in ??
