Okay there I just used every swear word imaginable .I actully wasted 15 minutes of my life arguing volume metric efficiency on a god damn ls engine ,jesus can I buy my time back . short story is this my buddy is finishing a 1989 civic ef RHD with 300 HP /1.8 liter toda race engine with itb's . We are talking about this at the store when somebody overhears us , & proceeds to argue with us telling us that were wasting our time and that is stupid to do . Then he seriously has the balls to tell us to put a frikin corvette engine in a civic . Lol. that's when dudes about to throw punches cuz I told him to grow up pushrod dinosaur ..lololol.
