im swapping to a pi intake manifold and i cant seem to find and pics of where and how much rtv to use. also ive read many threads and some use the npi gasket and others use the pi gasket witch should i use? where your supposed to tap a hole for that sensor on the front of the manifold, what exactly does that sensor sense because it seems like it is just reading the water temp twice and i was thinking why not just splice the wires from that one to the other so there is only one sensor but the computer still gets the reading it needs. i also got a bigger fuel rail should i put it on or sell it? any gains from it?
