How many miles are on the motor?

Have you done any work recently, as far as maintnence?

First, do a compression check on the engine to help determine if its healthy enough to turbocharge, and post the results.

Establish a budget for this project, and give us more info on the car so we can help you get the most for your money. 99% of the time, its cheaper to source everything seperately, some parts can be had used, in good condition at a fraction of the cost.

Also, what are your plans with the car? Street, autocross, drag, etc?
