ok i have an b18c1 (gsr) motor in a 96 civic hx
my question is would an oem style radiator with 1 row do the trick for keeping it kool or should i upgrade to a 2 high preformance alumium radiator.

thanks for any replys.

It should be fine. If it's not as cool as you'd like, you could always buy an aftermarket thermostat and fan switch.
