I own a 2008 WRX Sedan and currently am running a Stage 1 tune from Torqued Performance and love it. I have the access port and everything I need to upgrade to the 2.52 tune from TP (link below if you are interested). It basically consist of just swapping the stock 2008 turbo for the VF-52 turbo that is on the 09-10+ model WRX, I BELIEVE. I am buying the VF-52 turbo for $200 from an individual parting out a 2010 WRX with 48k miles on it. I figured for this price, I would take the risk and hope it works (i believe the car is stock). I have read multiple threads, some stating that other engine modifications are needed and some not. I need to buy a downpipe aswell, which I am thinking about getting an Invidia Catless DP. What do you guys think? Is this worth the hassle? Is it an easy swap? From what I understand, I believe this was the only other engine modification that gave the extra power boost in the 09+ model. Also, i'm not familiar with the term "boost creep" that are known in result of a Catless Downpipe. I live in Michigan and emission testing and sound is not an issue. Is this bad and easily recognizable or am i better off just going catted? (I don't want too if needed).
I know this is a lot of questions and I appreciate any input! I need to know before I buy this turbo what i'm getting myself into from you guys. Thanks for reading, feel free to post your opinion!
