Breaking stuff comes with the territory..if you mod anything..plan on something breaking because it will eventually happen and of course have some money aside in case it does. You can do a topswap/headers/intake and tune and your not going to be hurting the reliability of course you can easily lessen your chance of breaking anything by not driving like a idiot and screeching tires from every stop. I modded mine..started 4 years ago have yet to have to replace anything do you 'beating' on it...stuff like cv axles/starter etc then again I don't drive my car hard all the time.
