alright heres the deal. i had an 00 focus and wrecked it. now i have an 01 zx3 and i really want to mod it. just some small stuff, tb, intake, and exhaust. i figure that'll make it feel like a whole new car. but i still have to get around my dad. hes afraid that if i install a tb and intake, then i run the risk of ruining the engine? is this true? i need some ammo to fight back. also i have a fc tb, and had an intake but sold it. now i want to get another intake. is there any cheap intakes i can get? just how difficult is it to make my own? thanks.
