vvti is not bad its just more wiring involved and more complicated if you were to put in cam gears etc,for the fuel economy gains over the non vvti motors its just not worth it. non vv ti motors are just straight up user friendly,very simple mad easy to work on and just makes mad power it just wants air n fuel no variable valve or vtec lol

if you talking about the 1st gen 2j motors 93-95 you only need 1 ecu.i dont know about the vvti motors
