Bought my 2011 WRX early summer of 2012. Looking to start modding this coming spring (tax return). I want to achieve 300WHP and i need a little help from the experts here on what mods will get me to that 300 mark, not the cheapest, BUT the safest. i know there really aren't any guaranties when modding but im sure some routes are safer than others. regardless, i planned on getting the SPT cat back (not crazy loud but still sounds sexy) / Perrin intake (i know the stock intake is good up to 350HP? - but any aftermarket intake lets the driver hear their turbo much better than the stock intake) / lastly a tune...(accessport / dyno tune?)
So the question is...with the SPT exhaust, intake, and tune do you guys think 300WHP is reachable? if not what other mods would be required?
And some info on a tune would also be appreciated. (how many hours in a dyno is required to yield a safe and dependable tune).
Reliability is my biggest concern. If i have to spend a few more bucks to assure myself the mods and tune will be reliable then i will do so.
Thanks in advance for any and all information!!!
