To all, i'm having a problem with my 1997 honda accord. I currently have in place an F20B3 engine with a 2001 acura integra gearbox. The problem i'm having is that before with transmission i used to get a top speed of 100mp/h. Since changing the transmission and installing a gearbox, i'm now only reaching 107mp/h. I replaced fuel filter, serviced engine, timed, correct air pressure in my tires. I there is anyone that can assist please do so. I eagerly await a reponse.
