Ok, I'm helping my friend with his B16A in a 4th gen Hatch. He just impulse purchased a $2,000 head off of eBay. It's a BRAND NEW JDM ITR head right from Honda that comes with EVERYTHING. We have intentions of putting this on sometime this winter. We have a couple quesitons about this - - What kind of power can we be expecting? - How will this compare to his current track time of 14.9 1/4 ? - What kind of compression ratio will he be looking at? - Can we use the same ECU? - What headgasket to use? - Will he have to upgrade the fuel system? Current mods to his B16A include: i/h/e, V-AFC, Spoon Spec chipped PR3 ECU Any sugesstions on what to look into or what we will have to do for install would be appreciated. Thanks!
