Compatible engines
 

My buddy has an '89 Mazda b2200 and needs a new engine in it asap, We need to find a compatible engine to get the truck running again, So far all we have seen is an 86 B2000. Would they engine out of that work? If not what could we put in it. Need an answer by Friday since it's the only day off we share to go to the junk yard.

Thank you in advance:)
