Head porting for the do it yourselfer

[d_m_kolb]

This is my warning to you. Have a idea of what your doing before try to do this mod. If you screw it up you'll be looking at some very costly repairs and you'll be down a car until you buy a new head. On a 1.8L engine this mod will probably yeild you around 5 to 8HP if this is the only mod done to the engine. The more mods you do to your vehicle this mod will enhance them if done correctly. This is a great mod if you plan on doing other mods like, CAI, bored intake manifold and throttle body, exhaust, etc. This mod will increase all these others mods. With that said enjoy. http://www.sa-motorsports.com/diyport.htm
