Right now I have a jdm d15b in my 5th gen 4 door with intake header exhaust si tranny and clutch net cluch. I am going to sell that car cause I have a love for hatches. Well, I am looking at a 6th gen hatch and they come with a y7 if I am correct, if I put a y8 head on that, without doing any other mods how hard would that run? what would the compression be like, and do you guys reccomend something else for a low budget. I mean eventuall I might get a b16a2 or a b18c1 but that will take a while to save for, so for a mod like head and flywheel would that be fairly fast?
