Goal : 300whp and keep it safe for daily driving!

**Nihte21** · 07-09-2012 05:43 PM

I'm looking to add a few simple mods to increase my 2012 wrx to about 300~, but I also use this car as my daily driver so i dont want too many mods to stress it too much. I dont know if mods decrease the life of the car or anything, like i said im pretty new to this, any help would be greatly appreciated so if you leave a link that I have to read even that would help me.

Downpipe (or full turboback exhaust) + retune = Stage 2. Do that first, decide if you need more and go from there. Maybe add an intake in the mix if you want to spend the money.

Thank you guys!

On the 09 n later cars a good stageII protune will put you close to the 300whp mark and a little more torque. I suggest upgrading the fuel pump.. but otherwise everything else the factory put there minus the dp and tune.. will get you to 300whp as long as your tuner knows what he's doing.

Why do you suggest upgrading the fuel pump?

I think getting 300 whp from just an exhaust and tune is pretty optimistic. You're more likely to get in the 260-270 range.

**mangostick** · 07-09-2012 07:57 PM

Because you can never have enough fuel on demand.

300wtq is definitely attainable and in all honesty that's more important on the street than hp is. Even though 300whp is reachable on a VF48/52

go play with your porsche and leave the little people alone.

You'd be surprised, Scott. There are a number of 2011-2012 WRXs kissing 300whp on stock injectors and turboback exhaust on reputable dynos. I was skeptical at first as well.

Don't you max out the stock injectors before the fuel pump?

I agree tq is definitely more attainable and useful, but I'd like to see a dyno graph of a 300 whp WRX with only a TBE and tune.

If you consider a high reading Mustang a reputable dyno then I'm sure you can find a number of them.....

Back in the real world though even with a stage 2 STI (which has a bigger turbo, IC and injectors) it's very hard to get 300 whp.

Since when is a dyno considered "real world?" after all it is just a tool. A car may read 300whp on one dyno and 350whp on another with a different correction factor. The same car exists in the real world, does it not?

Anyhow, back to OP's original point, a TBE, TMIC, and tune may get you close to the 300whp, but don't be disappointed if you don't reach the mark. On some dynos you may, on others you may not. 565cc injectors will be holding you back at this point.

On my 11 wrx I hit 305whp and 330tq on 93oct with Fms tmic, Cobb intake and box, invidia catless dp, n1 race exhaust, FIC 775cc inj, DW 65c pump,

**Anub1s** · 07-09-2012 10:22 PM

^ 305WHP and most decidedly more than stage 2.

I'm going to add to this that shooting for numbers is kind of a fools errand, not to mention a money pit. Take small steps at a time, add a couple modifications, retune and see how that feels for you. And like I said above, if it isn't enough, do more.

A stage 2 WRX is typically more than enough for your average driver. I'm still at stage 1, thinking about stage 2 soon, after 6 years of owning it. Then again, I put more stock in handling and braking more than I do in straightline silliness.

you will NOT see 300hp out of the stock intercooler and BPV. You may on a higher reading dyno with injectors and a fuel pump but your pushing the limit of the stock tmic and bpv. Even at stage 2 levels most are close to max on injectors and bpv.
