Don't waste your money on cams. An exhaust, K & N's and ECU upgrade from Renntech, Evosport etc., will get you to low 14's or about 260 hp.'
I got my buddy's NA coupe to a 14.3 doing the K & N's, my own custom exhaust and fooling the stock ECU with potentiometers to connected to the MAF, intake air temp sensor, and coolant temp sensor circuits.
