i guess it all depends on the condition of the car, how much you can spend and what you want the end result to be; all of these cars can be made to be very high performance. the integras are an older car and may be in worse shape and possibly abused more thereby needing more TLC than the RSX. i owned an integra type r back in 02 and put about $2000 in mods and had a car that would top out at 155 and corner like a race car
