I just picked up a 2011 wrx hatchback in rally blue - I have been interested in getting one of these cars and I came across this car with 16000 miles on it and I couldn't pass it up. I've had an impreza before (a 1998 that I drove into the ground) and I've been a huge subaru fan ever since. I'm no stranger to car modding. I had a 2000 Mustang GT with a built motor, supercharger, and methanol injection that made an honest 450whp (lost it in a flood, one of the saddest days of my life ). Anyway, that car taught me a lot of lessons that I want to transfer over to this car.
First, I need to keep it very reliable. I realized with my other car that the more aftermarket parts that ended up on it, the more bugs and glitches I encountered. Every time I smelled something burning I would panic, assuming it was coming from my car.
Second, there is such a thing as too much power. My car made too much. I had 315 nitto drag radials on the back and they were useless - I could smoke the tires at 50 just by flooring it. This is a large part of the reason I went AWD this time.
Last, I have kids now and I am very interested in keeping the car driveable and quiet. I don't want to lower it and have to take speed bumps at an angle or slow down to a crawl to avoid scraping my bumper on a driveway entrance. I don't want it to be too loud or draw too much attention.
Driving this car has been a learning experience. My supercharger car had no noticeable step in power - the higher the rpm, the more power it made. This car has a definite kick around 3k which is interesting, and i also notice that it runs out of steam about 750 rpm or more before redline. The turbo lag is what it is, I'm not too worried about it. I would like to beef up the top end though. That is what I would like to focus on. Is that a limitation of the turbo itself or is there a bottleneck somewhere else?
Anyway, I've done my research and I'd definitely like to keep the stock catback but go with the cobb AP and catted DP (stage 2). I'm going to stay with the stock suspension stuff for the reasons I mentioned already. Is cobb generally considered the most reliable aftermarket manufacturer? I see that their stuff costs a little more but I'm happy to pay a few dollars more if the quality is good. Beyond the stage 2 upgrade, what else helps the top end power?
I don't really have a target in terms of horsepower numbers, just want to have some fun and tinker with the car while improving a weakness I've noticed.
Thanks for any advice.
