I wonder if anyone can help answer my query. I am a big fan of Preludes and have owned several over the past few years and during those years I have acquired the skills to maintain and fix my preludes with basic expertise. I would like to enter the next phase and get down to the real nitty gritty and do an engine swap. I currently own a Honda Prelude Gen 4 1994 reg. It is a meager 2 litre with a F22A1 spec engine. I would like to boost the car by chucking out the old one and inserting an H22A engine from a Gen 5 VTEC. First question, is this possible with the vehicle's current bay structure or do I have customize it in order to accomodate the new engine? Second question, providing I do not get put off by the response to the first question, what other components and parts must be changed in order to get the best out of the new engine? I know that buying the 5th gen would be cheaper but I am not concerned about that. I just want to play!!!!! :D Thanks in advance for your answers. Marcus.
