You can, but what's the point? Four things are going to happen:1) By doing this you will invalidate any warranty or implied warranty on your car. Now sure, you may be out of warranty by now. But there is also an implied warranty on a car. If you buy an Acura and one day it sets on fire. You can rightly sue them for building a shoddy car that sets on fire. If you modified the car like this, it's tough luck on you.2) The car is no longer safe. The transmission, brakes, steering, tires, wheels, chassis, and suspension were never designed to handle this kind of horse power. So now you either get the expense of upgrading other parts of you car, or you have an unsafe car.3) Your insurance is now invalid. If they find out after an accident that you turbo charged your car (and trust me, they look for stuff like this) then you are SOL and they are not going to pay you a dime. Now the other person involved in the accident is suing you personally and you end up broke. Of course the alternative is to tell your insurance company. Why don't you do that on Monday? Call them up and tell them you are thinking of turbo charging your car and see what your new boy racer premium is. If they continue to insure you, I guarantee you won't like the new rate they offer you.4) For all of the above reasons, the next buyer of your car is going to think you are a boy racer. They are going to assume that you thrashed the ever living hell out of your car. They are going to assume that the car is going to be an unreliable POS. This is going to substantially affect the value of your car. So you waste a bunch of money customizing your car, only to lose every penny you spent, and have the car depreciate faster than it would have if you'd left it alone.So seriously, don't do it. Save up the money you would have spent on the extra insurance. Save up the money you would have spent customizing your car. Take all that money and use it as a downpayment on a newer faster car.
