Your friend probably meant polish the head. What that dose is allow the air/fuel mixture to flow through the head easier. Less work for the engine and taking in more air = more HP.hybridvirusss said:*polishing the headers ( no idea how to do that.. my friend said it adds hp though)
BTW welcome to the form. I think everyone will agree that everyones a noob once and this is probably the best place to expand your knowledge on these cars. There are people here who have done/know how to do basically anything that the CRX your looking at would need. Good luck with everything. Looking forward to seeing how it turns out.
One more thing...How much are you planing on spending on this car. Knowing what price range you have to work with will help determine what you can do at this point.
