I just ordered a Terrain 2.4l AWD I wasn't sure which motor to go with.. I'm a guy who likes to buy aftermarket stuff for my cars and I have been reading that the ecotec motor loves to be tuned with some motors up in the 500hp range! Not like I'm going to go all out and make my terrain 500hp but if they will make an exhaust , cold air intake and a programmer for it that would be nice .. I see there are mods for the other versions of this motor so I guess why not this new version. So that is why I picked the 2.4l instead of the 3.0 v6 I figure when the mods do come out I will be right with the 3.0 hp or beat it . Plus the fours are better tuners than sixes ..
