yes the k24a4 and k20a/a2 head is good for all motor but if you want to boost it in time a b18c with a lsd tranny will only run you about 3500 witch leave you some money for the turbo kit but then again you will need 1000cc injectors handata S300 aem fuel rail a bigger fuel pump like a 255 and fuel regulater and you can get 300whp out of it witch is pretty fast on the street here
