Bald Eagle Swap: 1990 Nissan 300ZX LSx V8

, , , , , 2

The 300ZX was a 2 door sports car from Nissan during the great Japanese sports car boom of the 1990s and featured a host of technology in a Isao Sono & Toshio Yamashita designed body. Power came from a V6, which was available with a tire melting twin turbo setup, but today this Z has been given an injection of freedom in the form of a 5.3 liter GM V8, which is described by the seller as an LSX, but it is probably an LM7 from a 2000-2007 Chevy Suburban. This guy is ready for the 4th of July, are you? Find this 1990 Nissan 300ZX LSx V8 offered for $7000 in Groton, MA via craigslist. Tip from Rock On!

VEHICLE IS AS IS. Not responsible and no guaratee for defects known or unknown as car is highly modified.
Not a daily driver – needs to be gone through by qualified tech to be considered safe/reliable,.
Not sure if odometer is 100% correct (shows ~117k) and will sign off that I’m unsure.
Car must leave on a flat bed or trailer. Has an unidentified brake fluid leak. Although I cannot duplicate why, found reservoir almost empty after the winter.
Things I would consider to do.
correct exhaust system
get an OEM GM accessory belt drive/assy on the engine. Custom set up not as reliable.
Car had AC – possible to add compressor etc for AC with OEM accessory drive as above. Will include spare nissan evaporator.
Maybe do a GM oem harness and ECU with MAF if desired.
Oil pressure gauge intermittent – likely infamous Nissan sender issue. Other OE gauges work good including Tach, Speedo, Water temp..
I am not a big reciept saver, but have a few…
