I have a 2000 honda civic si. Everything is original (stock) besides I have a b18c1 block with type r pistons high compression stock b16 head with stock b16 headers a k and n air intake typhoon and manifold and tranny everything is stock besides block.I have an apexi full exhaust besides that its all stock. The car runs and pulls good just seems like its not at its full potential. Its my dd so I wanna have a fast dd and reliable engine. So im thinking of getting some private Label*MFG*Power Driven B-Series header features a true 4-1 merge. The link to em http://m.ebay.com/itm/151314596042?nav=SEARCH. Any reviews on them are they good. Also im wanting to put some cams im running the stock b16 cams and idk which would be best friend says the comp cams are good from jegs but im not sure. Also the skunk 2 ones if i can get some feed back on this and what is recommended and best for this build I wanna make 200 or more hp on this. Let me know please and thank you
