Hi welcome to the site! Now if you got 2500 I wouldn't suggest a H22 swap...You nsound like you are really new to the whole import racing world so I wouldn't really suggest it mainly because of that... Do some research and don't just go head first into swaps it will prolly turn out bad. Now as for the h22 swap it will require a whole lot of work... the h22a swap runs about $1950 not including shipping (engine,trans,ecu) and since your car is only 1.5 you got to go through a whole lotta extra bullsh*t... You will need to redo part of your front suspension (since you are going from 4 spd to 5spd and you will need to make some things stronger to handle all the extra weight) then you will need to fabricate your own mounts which really isn't that easy...and you gotta be carefull cuz you dont want some cheap ass mounts that will break!!..Then there is wiring changes and other bullshit...main point I wouldn't suggest it. But that can be partly because I dont like the h22a swap in a 88-91....unless it is for track it is kinda a waste for street. But that is just my 2 cents... Now I would suggest starting out with a b16 or you can do a ls-vtec using a b20 block (which i think would be best for you). And why you say it is weak? You prolly are thinking about a b20 in a crv....well the crv weighs a whole hell a lot more then a crx or hatch....let me give you an idea...a h22 you get 200hp...an b20 is 126hp notincluding the b16 head on it...a b18c (type r) 200hp...and they are a lot easier then the h22..I would say chill out a lil bit and do some research...if you have any questions just pm me i will be glad to help...
