do you plan on boosting? what is your budget? what are your power goals? we need a bit more info to help you on this... be fore warned, there will be some conflicting views on what engine to get. me, i'm a sohc fan, d16z6 all the way for a boosted application. but if you have the money you could go ls/vtec turbo'd. or you could build an n/a gsr... the options are limitless...it's all about your goals and how much cash you want to spend.
