low mazda

ok fellas. I just rebuilt my engine in my 4x4 yota. I tried cranking it and it just turns over and over. every so often it will crank and run fine, but when i shut it off, it wont start back up. now we checked the compression and it reads between 25-50 psi acrosss all 4 cyinders. The book says its supposed to be 175 or so. I put the engine back together exactly like the book said, and I can't seem to figure out what the hell the problem is. Someone told my dad that it was the rings in upside down, but someone told me that if my timing was off one tooth on the cam gear then the valves would still be open a little on the compression stroke, which would cause no compression. Anyone have a clue what the hell is going on here?
And the beast of it all, is one day it was running fine, but still not right, and it got too damn hot and cracked my radiator. does anyone know if the Mazda 2.2 radiator would work, since I am putting a 302 in my dawg?
