hey i had a few noob questions. i am looking for a small turbo that will spool fast and be good for only about 200whp. i don't need anything to bullet proof because i am only going to be pushing about 5 psi for a while. what kind should i get? where should i get it? if i were to boost about 5 psi do i need to change my factory injectors? also what kind of engine management should i get? has any one tried the cheap cast ebay manifolds? do those crack easy too? and what about the down pipes are those bad too?

here is the mani i am talking about.
