BE WARNED.... MY ENGLISH SUX

I recently bought a 1993 Del Sol with a 1.6l vtec. I have driven a 1994 honda civic 1.6l vtec for about 5 yrs now. When I bought the Del sol off of CL the owner fail to share the fact that it had a blow head gasket. I went ahead and fix the gasket (no resurface or lapping because i was going to find a core and rebuild it from the ground up). Recently the oil light started to flicker so i checked the pressures, it was 30@ idle and 50@3k rpms but after about 10 min it dropped to around 8@ idle and 28@3k. I am guessing that my main and rod bearing are shot. I had a couple question i figure some of you experts might be able to help me with.

1. Is the 92-95 1.6 CIVIC engine and man. tranny a direct drop in for my 93 del sol?
2. What do you guys thing about the oil pump problem.
3. Any ideas on a band Aid fix...ie Just replacing main and rod bearing to get by for a while i find a core to rebuild without having to rush.

Thx
