2003 mazda protege 5 engine options
 

Hey new the forum i recently just bought my old mazda protege 5 back from the guy i sold it to a few years back and he ran it out of oil and now it sounds like a jackhammer.. I haven't messed with it at all since i got it back i unloaded it off my trailer and parked it in the driveway.. It runs and drives but doesn't sound good at all its a main/or rod not sure just going to look for another engine. I called around to a few salvage yards and they tell me the 2.0L auto and the manuel 2.0L wont interchange and that since my protege is a 5 speed i have to look for another manuel 2.0 didn't know if thats true or what? Because its alot easier to find a auto engine compared to finding a manuel 2.0.. Next thing is i wondering if a engine out of a 1996+ mazda 626 with the 2.0 would work. and is a ford focus 2.0 the same those are a dime a dozen around here.. just need help finding the best options for this car thanks guys
