Max Boost on Stock Internals

My buddy has had his 2002 WRX Wagon for awhile now and his first mod is going to be a MBC. I've done some research and cannot come up with the max boost you can run on a stock motor. Do you guys know how much boost you can safely run? Any recommendations? Thanks!

Holy heck, did you read the thread before yours?

Holy Hell, sorry I haven't read every thread in a forum I never come into before I post a question. I've done a fair amount of research and come up with nothing. Simply typing 17psi would've been great, thanks for your input.

We encourage the use of the search feature too, on the whole of AF ;)

I understand that, and I'll be sure to use that next time. However, for somebody who owns a Nissan and has never been in the Subaru Forums, I wouldn't expect to find the max boost one can safely run on a 2002 WRX Wagon under a post labeled 2005 WRX. Either way, I got what I needed, so thanks.

The 2002 and 2005 share the same engine.

A wagon is a good choice though ;)
