here is the info i got from the dyno for those of you that think u might wanna still be n/a! If you could add this to your main post i'm sure some people would love to look at it.

first off my car info
2005 2.5RS Manual transmission
Injen intake
2.5" Techworks Header
2.5" Techworks cat delete pipe
2.5" Techworks mid-pipe resonated
2.5" Techworks custom glass packed/resonated muffler
Perfect Power 6 self tuned

Picture of my dyno graph.


Explanation of my dyno graph. ignore the dotted lines that was the map rallitek gave me off the shelf! and well it sucked. The other solid line is my own self tuned map. As you can see i have a pretty much straight line on my torque curve it started much earlier than 2500 rpm whihc means no lag and power everywhere! Also if you took notice my torque curve stayed steady at 6200(rev limiter) and the hp was still gaining! If i could flash the redline higher i'd definitely make more power.
As it stands now i have a Naturally aspirated vehicle putting out the power of a stock WRX with a WAY better torque curve as i have no turbo lag/spool to worry about.
Now one other BIG thing to note is that with this setup i get UNBELIEVABLE milage. on a full tank I get about 700-800kms not sure exactly what that translates to in miles but i believe its about 500-550 miles per tank! this is even under VERY spirited driving.

So anyone wanting to go with a n/a build these are the pros:
awesome power band, power everywhere.
milage is bar-none better than any turbo subaru out there.
definitely a reliable safe build.

cons:
well you all know it n/a will never make as much power as a turbo car in the long run.

I'll keep you all posted next year wheni get more done to the car intake short/long block.

Hope this info helped!
