What's up guys I'm fairly new to modifying Honda engines, but I would appreciate more information on building my street car. I have an 03 ep3 with the k20a3 motor but I would like to achieve 400whp safely and reliable. Would I be able to safely reach that horsepower with pistons, rods, cams and a solid turbo kit or would it be necessary to swap heads (k24a2) for example? Any information will help. Sorry if this has already been discussed. Thanks in advance!
