lots of cams, compression ratio bs upgraded injectors all the basic mods,and a ton of dynotime to play with the cam gears and you might get 230 with a ton of cash. i tried and only got 220.3 with an ls vtec swap and a crap load of hours on the dyno. its easier to go turbo on stock internals and make that goal. but to each his own. good luck with the project...
