Question New 2 Subaru so i'm just going to ask it... be gentle...


I'm new to Subaru but I've been a fan since the birth of the bug eye. I remember being in college and building a '94 Del Sol with my roommate that ended up making 318 whp on pump gas. We started started going to car cruises and I saw the future love of my live. I saw a 2002 WRX hatch and I was hooked... then he fired it up and I heard the flat 4 rumble and I was in love. Fast forward 10 years and now I'm established with a great job and a new house and I'm starting a family. Sooo... I sold my boat and now I'm getting rid of the gas guzzler SUV (I needed to haul the boat) and I'm finally getting the car of my dreams. I want a 2010 - 12 WRX. I keep saying I will leave it stock and enjoy the vehicle for what it is but I know me, and I know I cant leave well enough alone. I have already decided i want the sound of a axel back or cat back exhaust. However, I have read unabomber's manifesto among several other articles, posts, etc. Imagine my disappointment when I discovered that there is little you can modify without a proper tune, and an accessport cost around $600. So, finally, getting to my question (sorry for my rambling dissertation)...

How much can I do to my future Subaru (performance mods) before I have to break down and pick up an accessport and have my car tuned? Can I get a CBE without a tune or will I have to settle for a ABE? In Unabomber's manifesto I read about intercooler piping and the improvements in flow buy upgrading them. Can this mod be completed without a tune?

I have scanned pages and pages of this forum and haven't seen anyone who just laid it out for new users/owners... I probably didn't look in the right place, and i half expect to be redirected to the appropriate thread. Any assistance or advice would be greatly appreciated. Please take it easy on the new guy.

I plan on getting my WRX by April as i live in PA and I'm waiting for most of the road salt to get washed away so I don't hurt my baby. When I get her home i'll be sure to share pics of my WRX.

Thanks all,
Bestkept

Cat back exhaust will be fine without a tune. Any other mods you can do without needing to tune the car aren't going to make a difference. There are zero intercooler pipes on a stock 2010-12 wrx. The intercooler bolts right to the turbo and goes to a small throttle body hose.

Glad to see you read the Manifesto. Go back and read the section about tuning and tuners. Bottom line, there's not a whole lot you can do without tuning. Not to mention, tuning is where you're going to get the best bang for your buck anyway. Even just a tune with no physical upgrades is going to net you some significant performance increases.

And if you can't afford $600 for an accessport, you probably shouldn't be looking at a 2010+ WRX that you want to tune anyway.

You don't NEED to break down and shell out $600 for an AP to tune your car. I believe a tactrix cable and an e-tune (from a tuner like Torqued Performance) could save you $480. But personally I like the AP (I'm currently just at a stage 1 tune).

Unfortunately tunes are required for basically any modification that can increase power if you want to see gains and/or not blow your engine up. So a downpipe or an intake without a tune is a no-no. A cat-back is fine though.

thanks guys you have answered a lot of my questions. i didn't mean for it to sound like i was going to take my future scooby into the 400 whp club... I fully intend for this to be a daily driver. I just get a little carried away from time to time. Money for the accessport isn't a problem... its just that if i start down that road there may be no stopping so I wanna keep it as stock as possible but still have a nice SOUNDing and looking car.
I appreciate you taking the time to help me with my concerns, and i'll look into finding a tuner to assist me in my endeavors...

thanks

On the other side of the coin, the access port can be helpful if you are not running a boost guage or if you want to see what your car is doing (from temp to boost and more). Our cars should come from the factory pre tuned at stage 1 and you'll notice a huge difference. The AP comes with maps for the AE Intake or the Cobb Intake as well so that you can run an off the shelf map with either intake. If you do decide to go stage 2, just be warned that the 3G WRX's are prone to boost creep with a catless downpipe and running the off the shelf stage 2 map. A protune will definitely help after that point. Speaking of protunes, using the Cobb AP for a speed density tune is the way to go and you can relatively make the car a 300+whp daily driver beast for relatively nothing...It will void your warranty though.
