ibr_adam09 Posted September 4, 2010 Share Posted September 4, 2010 Max boost 13.5psi from : http://www.cars101.com/subaru/legacy/legacy2005.html Link to comment Share on other sites More sharing options...
DRoc7822 Posted September 4, 2010 Share Posted September 4, 2010 I know the 07's LGT is at 13.3 PSI and then goes to 14.3 PSI at stage one. Not sure if it gets raised again when you go stage 2. I dont think the turbo can handle much more boost... thats why people upgrade the turbos so often. Link to comment Share on other sites More sharing options...

Crossing509 Posted September 4, 2010 Share Posted September 4, 2010 My peak boost is 18.75 psi on the stock turbo. I've been at stage 2+ for over a year now with no issues but I plan on changing over to a vf52 at approx 75,000 miles. ...Support your LGT community...

johnAWD Posted September 4, 2010 Share Posted September 4, 2010 At 6200 ft ASL I was making 12 - 12.5 with my '05. Upped that to 17 with a Hallman MBC. Link to comment Share on other sites More sharing options...
joeblow Posted September 4, 2010 Share Posted September 4, 2010 The boost issue is more about the intercooler and its plastic endtanks than the turbo itself. Most of the tuners aren't comfortable putting more than 18.5-19 pounds through the stock intercooler, but one of my buddies is running 21 through his until it blows. It's cool; I'm with the band Link to comment Share on other sites More sharing options...
Strizzy Posted September 4, 2010 Share Posted September 4, 2010 I've been pushing my stock turbo to 20psi on my stage 2 for the past year. I recently cracked a ring land and now in the process of having a new shortblock built and going with a larger turbo. My bad luck build Link to comment Share on other sites More sharing options...
