Order your alternator from PRIME and be confident that you will receive the correct one for your car. This listing is for a 1993-1995 MR2 with power steering. NA or turbo engine does not matter in determining the correct alternator. This is the correct unit for a power steering 93-95 MR2. This is also the correct alternator if your car has had a gen3 swap as the MR2 alternator is the same from 1994-1999 in Japan.
