The engine has problems, but nothing major like internals or anything, the car was actually suprisingly fast, even with 18 wheels & tires, factory freak?

I enjoyed beating v6 Camaros, Celicas, Cougars, Civics, Accords (havent raced v6), etc and probably my best kill was my friends 94 Integra LS w/ I/H/E, racing cat, pulleys, and cam gears, I had seen this car beat many, many cars including my old auto lude Si very badly, but I just ate him up with the 95 se consistently

I also consider all his kills mine too
but anyways, the problems with the engine is an oil leak, could be anything from the valve cover gaskets+one of the seals are leaking+oil pan and/or oilpan gasket, and since one of the seals are leaking its getting on the timing belt which means I will have to replace it=$$, as for the tranny I think one of the shift linkages went out, but I was just sort of "over it" in general, got me very po'ed and just wanted to rebuild or get a swap.
Now after hearing your guys suggestion, I am leaning towards a swap, best economical route to go, but maaan I luv my h23a

I am thinking h23a vtec, not frakenstein but the JDM accord engine, anyone have any information about that engine? Since its an H series im pretty sure it'll drop rite into the bay but concerns are ECU and Tranny and would this actually be better than h22a?
thanks for your input guys, please keep em coming, knowledge is power!
