Well a b16 is a good start for the money but being you have a four door you might want a little more power to propel that large compact you have so maybe an ls vtec or a CTR engine, but all the power in the world will do you no good if you don't have good suspension so i would also recommend getting a good set of coil overs like TIEN or SKUNK2 not those ebay specials. You are also going to need some good rubber around your rims so don't cop out with a "cheap set" of tires from discount tire. When it comes to styling your best thing to remember is you get what you pay for so keep that in mind when buying and don't forget if you have bad roads around your town don't buy a body kit that makes your car 10mm of the ground don't forget to check your local laws they all vary per state.
