OP - the search function will help you greatly. your question is one that requires a lot more info than what you have given. ie, is this a street car? daily driven? track? what is your budget? what is your end hp goal? what kind of collateral upgrades do you plan to make to support whatever end goal you want? centri or positive displacement blower type???
lots to know. as the owner of two boosted lx cars, i can tell you that doing your homework and research on various forums will help in your decision making. i will say this much, turbo set ups are much more expensive than most s/c kits, although the collateral upgrade requirements are often very similar depending on power output (fuel systems, internal components, etc)
