1991 Nissan 300ZX Description

1991 auto 300zx coupe N/A to TT conversion. Runs / Drives with clean title. Needs new turbo oil seals. Enjoy the power of twin-turbos with the insurance of an N/A. 154k body miles w/ 37k mile JDM VG30DETT+turbo transmission installed. This sat for a long time and I’ve recently gotten in back up and running. Great project car. Also a prime candidate for a manual swap. This is being sold AS-IS.
