G13B is a crazy engine, it revs like a motorcycle. it will put a smile on your face though, its like owning an original DA8 Integra XSi, it was a nice looking medium sized luxury sedan with climate control etc.
looked very decent IMO - rev that engine beyond 5000 rpm and that nice sedan then suddenly howls as the VTEC comes onto cam and hauls. Your margalla will become a similar car but at a lower power level.
mind you the G13B due to its wide angle head requires high rpm to breathe.
