Hey ive seen online how they sell ITR engine/tranny packages. i understand that theyre used but how do u tell if theyre any good? is it a shot in the dark? are those engines that are sold understood to be put through some kind of checks? or will the engine basically crap out on u cuz they all have 100k miles on em?

 

If you order from a reputable shop, then you will get a good engine. Some shops have a start up warranty, meaning the engine will start. If you order from a good place, you will most definately get a good engine.
