oaky the engine i have in my 91' LS is pretty dead for doing anything without me having to rebuild it has blown piston rings and has a nasty knock so what i was thinking of doing was to swap in a b18c5 but thats like 3500 for a new one but i can also get a b16a vtec for 900 in new condition so i was wondering if i would still have the power of the b18 and i want to be able to boost it with this new engine also and the choices are either the

B16A GEN2 XS-I OBD1 Long Block
B16A GEN2 OBD1 Long Block

which one would be better for me to get and boost.

really just wanna know if its going to have the same power and strength that the b18.
