since fuel systems usually can scale up from between 30-40%, and stock turbos can usually scale up in boost pretty well. I think 300hp from just an exhaust/intake and boost controller could be had. (and some fuel system tuning).

blowoff valve? upgraded intercooler?

please tell my what you think.

Im curious as the exact same question as Im a prospective WRX buyer in the near future.

Hello,

Since no one has one yet, anything posted is PURE speculation - aside from anything Shiv posts, which would be partially pure speculation - he drove one at Buttonwillow and all around SoCal last week.

That being said, I bet there's plenty of power to be had by killing the cat that's in front of the turbo! Horrible design for power, great for cold-start emmissions. Like most cars, I'm sure an intake and exhaust would help - Trey shouldn't take too much time to come out with upgraded downpipes, etc., and all that random stuff.

Note that the turbo is probably overworked as it is. Shiv said he noticed the knock sensor retarding timing while they were driving around. That and the smaller intercooler and the way the boost works all leads to the conclusion that the turbo is heating up the intake charge too much as it is. You'll want to upgrade the intercooler to a fatty one like the minnam one.

All those things should be good for more power. I dunno if 300 is that easy, seeing as how 300 is not totally common in the UK...

Of course, SCC will likely do a story on modding the WRX (duh, it's a subaru and we know they love scoobies) and then everyone can see the path and the results.

thanks for the information, I guess i'll just have to wait to find out. Anyway that it works out though, I'm sure I wont be disappointed.
