The H4 engines are nice, ive always liked Subarus but the truth is the engines arent that powerful. And id say its below average, if you look at the other technology out there: Honda 2.4L VTEC 198HP Honda 2.0L VTEC 200HP BMW x25i 215HP Mazda 2.3L 155HP Toyota 1.8L 2ZZ-GE 190HP Alfa 2.2L JTS 182HP Citroen 2.0L 170HP (C4 VTS) Peugeot 2.0L 180HP (206 GTI 180) Renault 2.0L 197HP (Clio Sport RS) Those are just some N/A engines i can think of that really make the Subaru non turbo engines seem lethargic. Now Subaru does compete with these companies, most of their vehicles are advertised as drivers cars and priced quite high but they fall short of these claims IMO. I mean they have an Impreza 2.0RS "RallySport" that has less than 150HP ? What kind of a farce is that ? Youd be obliterated by any run of the mill warm hatch or sedan (Hot ones would embarrass you), in fact the Jetta 1.4T would outpace it and the Jetta hardly is performance oriented like the Impreza RS is. Subarus engines n/a engines have not been great since the 1st gen Impreza GC, i think the standard 2.0L produced 100KW, it was one of the few mass production non turbo engines to be able to have such power back then. They have really dropped the ball since then, and whereas the rest of the market is movie towards smaller turbo engines Subaru refuse to offer turbo in anything but their highest end models. Theres a huge gap between the turbo and non-turbo engines.
