Does anybody know where I can find a NEW engine for my 96 Infiniti I30t ? I see alot of reconditioned ones but am willing to pay the extra cash for a new engine or one with less than 50k miles

You won't find a new one. The only engines you'll find are reconditioned or used engines pulled from wrecked cars. Reconditioned engines are used all of the time. Many times if you have a car under warranty coverage and an engine replacement is required, a reconditioned engine is used.
