hello, I have a legacy model 2000 with ej25,150 HP, 4S auto,and 180000KM . I want to increase the HP between 380 and 400 HP. Should I upgrade the same engine or should I swap it with another engine? If I was to upgrade it, do I have to upgrade the gearbox or swap as well. Please give me the best, the easeist, and the more convienient solution . Whatever solution you may recommend, we'd like you to give us a website we can visit and buy from.
