Replacement engine transmission question

I am replacing my bad 2.3 engine with another 2.3 from a wrecked car. I have a manual transmission, can the replacement engine come from a car with an automatic trans? If yes, what other parts would I need ? Pilot bearing?

Thanx!

A quick search on-line will tell you the answer for that but I believe they are the same. (short block on ford website only shows one option) If you're replacing a motor I would always advise on a new clutch, resurfaced flywheel and bearing set. No sense in putting in a motor then have to take it out 15k miles later to do a clutch. If you have the funds I would also replace all the lower seals on the used motor (rear main, pan gasket etc) before you put it in as well, especially if the replacement motor has 50k+ on it. It's out, its easy and a cheap insurance against leaks.

Thanks...I have purchased most of the other parts you have recommended. I called the local Mazda dealer and they wouldn't say yes or no in regards to the engine and transmission swap.

Are you a mazda3/6 or a fusion? These boards sometimes cross over. I would error on the side of finding a manual car anyway so you can have extra parts. There are differences in the long blocks some how because they have different part numbers.

Mazda 3 2.3 engine. There are far fewer Manual "engines" than automatic out there.

Engines are the same between them. But there are differences depending on year. So you might end up having to switch a sensor here and there if the engine is out of a different year.

Talked to one guy today and he said the difference between the auto and manual engines is the harmonic balancer. Is this true?

Nope. But those did change depending on year. Specifically its the tooth count on the pulley that changed. But they were the same on MT and AT cars in the same year.
