hell yea i have a 2000 1.6. they say that the 1.6 handles boost better than all of the three engines offered for the protege(1.6,1.8,and 2.0 which are all 4 bangers). if u really wanna do a swap i would go for the bpturbo which is basically the same engine with a turbo and 4wd which is y ur better off buying a hiboost turbo kit so unlike r3run said if u really want to make power turbo it dont leave it NA. the protege has potential to beast with a turbo on it, ask anyone on the mazda forums(protegepower.com is the best one cuz people actually try to help u unlike protegeclub.com where all people do is talk shit kinda like here)
