building a D series for a friend, its a d15a1 came out of my 1984. Honda crx. "boring little carbureted engine" wanting to do some modifications on it and a head swap-different rods-pistons ect. we want to go with a d15z1 vtec head off a 1994 Honda civic. but we want to use our dizzy and intake-carb set up. also wanting to use a set of billet rods and srp pistons from race engineering, just curious what all would be required for head swap, going with bishimoto level X cam with titanium retainer and spring kit, with a adjustable cam gear also. Any help is greatly appreciated, As far as flywheel-clutch-pressure plate I am considering to use the fidanza 8lb flywheel with a competition products level 1 clutch
