Hi, I Own A 2005 Ford Focus 1.6 Duratec TI-VCT (115ps), I Have Fitted a Full Magnex Exhaust And A K&N 57i Induction Kit, Any Idea On How Much More BHP That Gives Me... I Am Thinking About Fitting A Turbo Next But Am Not Sure How Easy Or Hard This Would be And What Kind Of BHP That Would Make, If Any One Can Help Me In Any Way Or Has Any One Done This Before It Would Help Me Out Loads, As Dunno What Sizes Turbo's Come in Or What Is Possible. Thanks :roll:
