I HAVE A HONDA CIVIC 1.4 75PS. I HAVE BEEN TOLD THAT THE ENGINE IS THE SAME WITH THE ENGINE OF CIVIC 1.4is 90PS. THE ONLY DIFFERENCE IS IN THE TRANSMISION. DOES ANYONE KNOW HOW I CAN HAVE 90PS (WITHOUT CHANGING THE TRANSMISSION)?

the difference between the 2 engines lies in the intake manifold, not the transmission. So if you swap the intake valve, you should be able to get close to 90hp

Any quick and easy way of telling if you have the 75bhp or 90bhp engine?
