I'm in the middle of a b18a1 to b20 (pre 1997 version) swap and have run into a couple of project stopping problems:

I am currently transferring over the electronics of the old engine to the new one. I have an engine coolant sensor on the back of my old engine block that cannot be installed on the new engine. It is supposed to go into a hole that is plugged on the b20. My friends and I believe that it was replaced by a new sensor on the thermostat housing of the b20.

The old and new sensors would obviously not be compatable. For the moment, my best alternative for dealing with the problem is to unscrew the new sensor from the thermostat housing and create an adapter for the old sensor by using a few pluming parts from home depot. I'd like to use the new sensor, but it would probably fry the moment I powered on the car.

The second problem has to do with the pcv valve. The b18a1 has the valve mounted directly on the intake manifold and going out to the block itself. I do not know where it is on the b20. I'm thinking that it goes on a vacume line going to the head valve cover.

Any thoughts on the problems would be appreciated. I've already consulted the integra shop manual and google.com. I do not have a CRV shop manual, but I can't find one for that year vehicle at the moment.
