F20B vs. H22a

I've got some questions on the F20b vs. H22a? Are they the same engines? are there more parts for the h22 or the f20? if i stroked a f20 to a f22, is it the same as a h22? is the f20 lighter? blah blah blah blah blah... yeah, if you could help me answer any of these comparison questions, thanks! :)

one more thing, which is better, OBD1 or OBD2?

I would go with the H22a it has 220 hp and 183 ft lbs of torgue and the block is alot stronger! It dont bother stroking a f20b if your gonna stroke one make it the H22a. Make sure if you get one dont get the american H22a SH it has a torque on demand system that in the end will not let the swap work correctly. Man all i can say is H22a because it is all around better it costs alittle more but its worth it. If you got one youd start buying parts for a prelude of the year of the engine! I can go on and on and on if you have any questions just ask!
