Well I bought a 1960 Beetle and i would like to know what modification i can place on the car to make it go a bit faster with out the gas consumption. The owner claimed that that the Beetle had a 1700cc engine but to be honest i cant tell the difference if you know can you guys tell me how and actually know what engine i have? Oh and does changing the rusty j tube exhaust pipes do anything the exhaust doesn't have the stock muffler it has custom one that are rusty. I put premium gas and change the oil every 3 months. If that helps
