Swapping engines in 300ZX

[gwb2709]

Hi, I recently bought a 1990 300ZX NA w/5sp and the engine is gone. I have bought a 1994 NA engine that also worked with a 5sp. My question is will I have to do anything different, like an ECU change when making the swap? I know there where some changes on the 1994 NA engine, injectors, adjustable cams, etc.

This is my second post, my first was in regards to changing the rod bearings in my son's 1990 300ZX 5sp. The information you give my proved invaluable and the Z is still going strong with about 4K miles since the bearing change....

i cant tell you for sure about everything working in the 90 chassis. now if you had a longblock and were slapping it in with the original manifolds and sensors,etc then i would say that you should be ok.
