I know what you mean, my 94 pulls harder than most other Integra's i've driven, but it could all be psychological too... but, something that was weird, when I have my 91 Civic Si - Stock (back when I was young and stupid), I had raced against a friends '90 Civic Si that had a header, exhaust and intake on it, and i'd always pull a few car lenghts on him... no idea why... many possible reasons, its possible it had a *special* engine, I was a better driver (haha, maybe not), his engine needed work, who knows...
