the f22b swap from non vtec to vtec is simple.. no oil lines or anything. you just need to get the vtec intake gasket. then all you need is an ecu. simple swap.. i did my t belt and all my seals with the head swap in 8 hrs.. keep in mind this was my first t belt and head. so ...easy... noticable difference in power as well. but i did this swap on my car this last weekend and it runs great
