Differences of 2011 wrx motor and 2011 sti motor
new here, wife has a 2011 wrx(i have a 2006 evo).
What is the difference between a 2011 wrx motor and a sti motor. the tally i can figure is 1) intake manifold is plastic vice red 2) 5 speed vice 6 speed tranny 3) turbo has different exhaust housing(usdm legacy gt) 4) top mount intercooler is smaller and plastic vice metal larger one 5) engine has (AVCS) on exhaust side only vice Dual (AVCS) so is the block and head assembly basically a 2007 sti version? did i miss anything? i tryed the NOOB forum and did not get much help. i am trying to figure out why the 2011 wrx has a different red line than an sti too?

Cams and turbo are obviously different, I believe the STI has different heads as well but I may be wrong on that. Rods are the same. WRX is 8.4:1, STI is 8.2:1. STI has a nitride-treated crank.
