Default 06 Forester needs a few extra HP's

I have owned turbo subarus but as Im getting older and I guess more practical Im leaning towards a 06 Forester 5sp.

What things could i do to give it a little more get up and go?

as in non-XT Forester?

Well...how much do you want to spend? Haha.

Really if you're worried about power, start with a FXT and then get whatever power you want with whatever turbo that will give you that power. This is the cheapest route for power.

If you really want to step to NA, then the major power gains come from an aggressive ECU tune and full exhaust including good headers (TWE). If you're willing to spend more, cams and head work will shift the power band up and gain you more HP up top. You can move to a higher compression setup along with upgraded internals, switch to E85 (requiring fuel pump and injector upgrades), and go hog wild on timing and get some decent torque gains. Cam choice can put that torque band where you want it. It really depends upon how much you want to spend and how much work you want to do with the engine. For just bolt-ons, you can gain 15% average power over the rpm range pretty easy. If you go wild and make a serious motor, but it takes gobs of money. Gains could be double though.

Yes as in non XT. Im not wanting major power gains just to pep it up a bit.

Since I posted that I looked at the XT........I think its a little more than Im wanting to spend. I found a really good deal on a 06 Premium 5sp one owner 4K below KBB.

I may go the route of headers, exhaust, sway bars and good cross drilled roters with some good pads. I think that will make me happy for a while. I should get the car this weekend if everything works out, which it usually dont in my world.

Thanks for the good info

Well the turbo Forester existed as old as 2004, so it's not terribly hard to get one well priced. It might be kind of hard to find a manual though since the vast majority of them were sold as an automatic.

For NA the comment of pep means low end and midrange torque. It certainly won't help you pass cars on the highway, but you will have solid grunt cruising around town. A full exhaust is a big gainer and a TWE header + full 2.25" high flowing exhaust gets you sizable gains everywhere. I'd talk to williaty about cam options and head porting. He's installed and run a lot of them and can guide you to the best option. An aggressive ECU tune with more timing can gain you quite a lot, as much as a full exhaust. If you don't mind premium fuel, you can run double the timing you will off 87 octane. You'll have to get the car tuned somewhere though. An odd upgrade will be Grimmspeed's phenolic spacer for the intake manifold. Frankly I don't know why it does it, but it adds quite a bit of low end torque. I have guesses, but I couldn't tell you for certain. The 8mm spacer isn't long enough to change the runner length enough to make any appreciable change in the intake manifold tune. It probably has more to do with offsetting the injectors or how the air flows into the heads. I don't know.

Slightly off topic but for suspension I will point you towards Swift's FXT springs. They're a great oem upgrade spring, a little drop and a heck of a lot nicer riding than stock. It's pretty much what stock should have been. Add an oem 20mm rear bar to swap out the tiny 13mm bar, and the handling gets pretty darn good.

For brakes, upgrade to the WRX front rotors and brackets and upgrade the rear to the larger outback rotors and brackets dubbed the "H6 upgrade." Add any decent premium ceramic pad to it, and you're sitting good. It neutrals out the brake bias and offers a little more braking torque. You'll just have to decide what brake pad friction coefficient you want to set the desired pedal pressure. Suggestions, Carbotech Bobcats, Hawk HPS, or EBC Redstuff, but there's tons of options.

Lol, I wasn't going to say anything. Cosmetics are a personal choice. I doubt OP intends to track his Forester, so it doesn't really matter what gets put on. If he wants dross drilled, so be it. If he was tracking, I'd still suggest blank rotors because they're still gone in a weekend.

I guess I mean with more pep is HP, like being able to pass cars. My wife has a 06 Legacy auto. I love driving it but it just doesnt do it for me compared to a 5sp.

Is this true, If i went to a 2.5 exhaust vs the 2.25 it would give me more HP and going smaller gives more TQ???

I will look in to doing to TWE with CBE and decide where to go from there. Thanks alot but feel free to add more.

I Youtube Forester videos and Im really liking the idea of doing a WRX swap on the forester. It of course will be a while but I can have dreams for now.

If you're going to swap a motor in or even turn a NA motor into a turbo, you may do it cheaper starting with a FXT. I may also suggest the idea of looking at WRX Outbacks as well. A Forester is 90% an Impreza, and the Outback wagon design is mostly only losing a little cargo space. The car design also does offer a little better fuel mileage, a little less of a brick through the air, lol. These are just some things to think about.

Some of your first upgrades for sure. RSB is like 100 bucks (usually less!) used. And adds A LOT to the driving aspect.

Downshift?

Unless she's a rare breed, your wife is going to hate your exhaust if you do enough to get any shade of power from it.

Not really. you can build a quiet exhaust that will make the same gains as the louder ones. A large, well designed muffler, will do a good job of reducing volume levels. The valve train will probably tick like crazy, but thats not as bad.

Shes a good breed. I used to have a 02WRX wagon with SPT and she never did complain about it. I think that was the best sounding exhaust for a turbo Subaru.
