stock internals

[redscooby]

does anybody out there know how much horsepower the stock internals of a wrx can handle?

i know the stock valvetrain leaves something do be desired. i have already replaced once cylinder head, one camshaft, three lifters, and three shims. but...that was partially due to my fault.

other then that..the stock bottom end is seeming to hold up well. you should be able to easilly get 300hp reliably.

key word....should

What was the deal with your heads?
