Sorry to jump in, but Ive searched and searched for specs and comparisons on my engine code. All the info I've seen says my engine belongs to an sti, RA. I got the car two weeks ago from japan and its a 98 wrx. The engine code is :ej207DW1KE and the turbo on it is a vf29. Is someone making a mistake with the year, engine by saying its from a sti? Or did the wrx come with an sti motor for that specific year? Thanks, from what i can see so far you guys know your stuff. Also can i get some links to sites with specs of my motor: cams, pistons, etc.
