hi all ,
i got my 147 2003 1.6 L recently which equipped with Full remsa exhaust with changing the header and of course removed the catalyzer
i put also K&N air filter (down the car in front of fan and ground )
but when i asked my mechanic that i need more acceleration and top speed (my top speed now stopped at 200KMH no more ) he advised me with to replace my current gear box with 1.8 gearbox or 2.0 L
so i asked you about this matter and if there any different between 1.6 , 1.8 and 2.0 L gearboxes and is it will be useful for me to change it
and also is there a different between flywheels for the three types
need your advises please coz i'm going to change it after 2 days only
thanks in advance
