Is doing the big three really worth it?

You really wont be able to "hear" a performance increase by doing the "big 3". What you're effectivly doing is giving the alt. and other electrical stuff more room to "breathe". It's the same as changing out the stock tube running from the air filter to the intake with a larger tube. You give the ability to pass more (air/electricity) thru it. Paul

It is going to depend on what you want to do with the vehicle. The first thing I would do is to replace wire and upgrade all the grounds. If the battery is oldish or currently failing then replace it as well. If your system demands much more power then what your current alt provides then you should up the alt. Being that you have an older car you have 2 advantages, first the draw that the car takes is much less then cars with ecu, gems, and bcms, second is that they are much easier to work with.Certified Security Specialist
