I am having a hell of a time finding companies offering performance parts for the Matrix. Decked/ported/polished heads, ported/polished intake manifolds, etc. Are there companies out there who offer these parts? I'm looking for companies on par with http://www.spswebpage.com in terms of offering nearly everything for the 1.8 engine.
if you want your exhaust headers ported, theres a guy on newcelica.org that does them cheap, named Boosted2.0.If you want your TB bored and intake manifold port matched check maxbore.com
