Hi List,
I own a 1986 300 zx with a good engine. It's not original, in fact I think its from a pathfinder. Thats another story it fits and worked as a z engine for 3 years. The plate on the Z says its a VG30 (B). I'm looking at a 1990 Maxima SE with a loud knock in the engine (bearing). The rest of the car seems pretty OK 200k miles a lot of new stuff, waxable paintjob , usable tires new brakes rebuilt auto tranny 30 k agoand 500 in exhaust work, $500 bucks delivered. And iy runs BTW. Any the question is can I get my 1986 300 zx engine auto tranny BTW into the Maxima auto tranny (VG30(E)). And what issues will arise? Any Fuel management problems? Which ecu would I use. Do I remeber something about doing this swap reversed and having to change oil pan and dipstick location?? Sorry for the long post .
TIA
Fred P

 

The short block should just bolt into the 3rd gen. As well as the heads. You will want to use the IM from the 3rd gen along with all the other gear (harness, snesors, etc).
