That depends, is the current engine running great? Have you done timing belt? water pump? Other maintenence? If so then I would go ahead with the suspension, it helps a ton. But if the engine you have now is not very good, then what good does a grand worth of suspension hop ups do for you while the car sits in your driveway after blowing up or breaking the engine? Just a thought, enjoy the project and by the way more than 2 inches suspension drop makes the car worthless, just thought I would help you out since I learned that one the hard way
