Welcome to NICO

No the ECU will work fine. no swap needed.

Good luck! on your swap! You ought to do the timing belt and water pump before you put it in unless you have documentation is was done recently.

Check you trunk also. It's Infiniti.

U don't have to but, 93-94 are the same but, U have federal and California models for emission purposes. Also the 95 ECM are one year only. I have done the VG30DE Engine Trans swap before and we dropped the unit threw the bottom. Like Brain said always replace what needs to be replacing while engine is out the car. The 2 EGR Tubes that run along left and right bank always are clogged with oil,dirt, and carbon buildup. Clean these and your enginesEGR System will perform correctly. Check and replace mounts if needed and make sure U remove/ lower the drive shaft properly or U will have vibration problems.
