It's a 2L turbo, makes 176hp stock. Runs fine, but the stock tune SUCKS. Mazda put some n00b in a room with the stock Protege ECU and said, "you have 1 hr to make this work with a turbo" and called it good. It stays in closed loop till 4K rpm, even in boost, so it has a bad habit of blowing the stock motor up at around 3-4K because the AFR's get around 17:1 sometimes. Then it goes SUPER rich (10:1+) till around 6K, and then finally leans out to a reasonable 12:1. Stock SMIC is too small and in a bad place, so it heat soaks after about 10 min. The inlet for the air filter is right by the hot side of the intercooler, and needless to say, that's not a great place for it.
Luckily there is a decent amount of aftermarket support, and some nearly PnP piggy backs that will fix the stock ECU's tuning issues. Pretty easy to get to 200whp with bolt on's. It's the DD, so I won't get too crazy with it, but it'll be fun to have a new toy to play around with.
