ok.....i have a 91 na converted to 88 t2...... now, i blew up the radiator that came from the 88 t2.... and i purchased a metal radiator out of a 89 automatic.... now, first off... the darn thing didnt fit.... but that is a question for another day.... does the auto radiator have enough cooling capacity for the 88 t2 motor???? my vehicle is overheating like crazy.... im just curious if its the radiator

 

the turbo radiators and n/a ones are the same series wise. so it should work just fine. im not sure about the fitment issues though. since you said it is metal it should work a little better than stock anyways. i hate the stupid plastic crap mazda put in, all of my family's rx7's have needed new radiators b/c of that plastic.
