I have the 2.0 liter engine. Here is what I want to buy and install: J-spec Intake manifold, camshafts, and piston set. If I put these all on would it be possible to tune the compression to get a significat HP gain? Anywhere near the FS-ZE engine? Like a 150 hp or something? I would just by the engine but they seem extremely hard to get a hold of and would be a bitch to ship. Thanx for any opinions and/or help.
