First and foremost, you need to consider how much money you have set aside for the project.Answer some questions... - how well does your car run? is it strong enough to handle the added power of super/turbocharing? how many miles are on the engine? do you have proper compression in all cylinders? is your clutch in good shape - will it be able to handle the added power? etc.- how much money do you want to spend? are you looking for a simple drop-in aplication like a jackson-racing supercharger? are you looking for higher horsepower gains in a basic (e.g. greddy) turbo kit? do you want the huge gains all at once or do you want to be able to add to your turbo setup?- do you have alternative transportation? if/when something goes wrong, you might not have a car to get you to work/school/whatever... installation and tuning takes time - especially if you're doing the work yourself.the D-series in your car is still a good platform to work on. I'd suggest buying a basic (again.. like greddy, drag, something similar) turbo kit and then adding to it when you'd like to develop more power. a properly sized, small turbo wont have any perceivable lag at all.
