im taking my head off tomorow and just wondering,

what sort of compression can a D16A9 ( i think that its the same as the U.S ZC ) go upto using stock ECU? we have 97 octane fuel at the pump here, also what sort of static ignition timing can i advance it to <safely> with this upped compression? turn the dissy till it pinks and back it off a few degrees! lol

im keeping it N/A for now, ive done a few calcs and if i take circa 0.028" off i should be hitting around 10.1

how well do hondas/d-series respond to 3 or 5 angle valve jobs?

im an engineer so all the machining work and labour is free to myself, gona open the ports up a bit as well,

thanks,


Ross
