89 crx motor swap

I am building a 89 crx wanting to know what motor to install, this will be a weekend play car..

I have a buddy that has a honda SUV bottom end with a B18 head on it.. i was thinking of that..

crv tec is what it is called.there good but the cylinder walls are thin. they cant handle boost or nos safely.i would go with a ls vtec and spray the hell out of it.it would be cheap and simple but run like hell
