this question has been answered a million times on both here and honda-tech.. most people do the ls or b20 bottom end to save money.. unless you are going to spend the money on rod bolts and you dont mind not reving it to oblivion everyday than yes.. its a good idea. Most people enjoy the tq they put down but some do miss the rev happy gsr/b16 bottom ends...

^^ not saying you cant rev the piss out of one... look at mspi 240 whp build... or the sticky about the ls/vtec builds at the top of this forum...
