Default Engineering/manufacturing of Our Engines

This may be an unusual question to answer, but dose anyone know of any web site, or books that go over how our boxer engines (2.5 l) are manufactured. I would like to know if we have a forged crank shaft or a cheep cast one. Same thing about our connecting rods and pistons. I know our pistons are probably case, but are they robust. I would like details, not a person saying they turboed their engine and nothing broke so far. Thanks

everything is cast in the EJ25. look in the tech articles on cobb tuning's site, those might answer some of your questions.

for high rpm, count on replacing the rods and pistons but the stock cast crank will be fine. boxer engines are easy on the crank, and there's no main bearing caps just two block halves. lots of support.
