It is possible to make impressive numbers even with relatively low boost, however, several fundamental weaknesses require a built engine when chasing a big boost, big power setup. In all markets except for the United States, production lasted through 2002, with a limited production Blitzen model sold mid-cycle under the 2003 model year in Japan. There is more power that can be extracted at the top end, but since the engine is usually installed in large and heavy cars (as the Legacy/Tribeca), to gain a significant power boost, large improvements in torque are required, which cannot be easily achieved with a naturally aspirated engine. Sound - it’s pretty hard to beat the sound of a flat-six engine singing through the rev-range, goodbye Subaru rumble, hello Porsche soundtrack. To combat this problem, we have developed the.
