ive got very similar mods to urs Daz.
im running 600cc nismo injectors with a sard intake fuel pump with a direct 14v power supply.
im also running GReddy cam gears, i think they are great on an RB26. they gave me more flexability when it came time for tuning. ie i had a choice between getting them tuned for outright power or sacrifice abit of top end for more midrange power/torque
