I have a 240z with the orginal L24 and tripple PHH44's, a Isky cam with 480 lift/280 duration, hardened valve seats, lightened flywheel, E-31 head, and a 2.5inch exhuast to a 3inch flowmaster muffler. The current jet sizes are Main Air-210, Main fuel-140, and Idle-57.5. I was wondering what any of you recomdend doing, should i rejet it or what? And if i do rejet it what do you think the range of jets i should buy is?
