seen many cars with a eg half radiator even turboed cars. also it comes standard on cars so do not think cooling will be a issue. even if you run the teg wire harness you just changing the fact that you were wired for dual and now you are wired for multi point, you will still (with the teg harness) have to wire the car\ harness for v-tec. i think its four additional wires (since you sre now going to be multi point) the solenoid, pressure switch and two others. at this time i do not remember what they are. sorry, hope the other info helps.
