Forester Tuning your 09 FXT

Id like to create this thread as a listing for those looking to mod out or those who have modded their 09 FXT. Sadly, Bigstick isnt tuning his Sleeper anymore but I would still like to know whats out there for the 09 FXT as I will be looking to do some more mods later this year.

Current Mods on my 09 FXt are :

18" OZ Ultraleggras w/ Yokohama 245/45/18
AEM Cold air Intake
SPT Cat-back Exhaust
EcuTek Tuned

Parts to come:

whatever else wont void my warranty



Please Post whats in YOUR 09 FXT !!!

Good idea for a thread!

I just picked up my '09 Black FXT yesterday.

Today I picked up my 18x8 et48 Rota Formula Mesh wheels in Hyper Blk.
Tires are 255/45R18 Falkens.

I wish I had been able to test fit before hand, I think I would have gone bigger! There is GOBS of space under there! I love the wheels but I think I will keep them as winters next year and get new summers next summer. Probably go with 18x9.5's with 275's!

- Next up is the mesh front grill and the bumper spoiler.

- Next next up will be sway bar(s).

- NNNNnext up will be coilovers.

- Upon break in I will get an Ecutek custom tune with a high flow catted downpipe and possibly an APS intake. Don't think I will go beyond that with power.

I will be getting the SPT front sway bar soon, so i will let you know how it works out. My wheels are pretty sweet, I dont know if I would actually go for 19s but if they work well for you, maybeeee next time round ill give it a shot.

Yup, definitely don't do intake without EM. AEM is particularly heinous.

I'm not planning to go with 19's just want to go wider and wider tires.

Are you doing the SPT front sway bar only? Do you find the car doesn't understeer enough? Why not get the rear bar first?

SPT Cat-back Exhaust here. Unsure where to go from here, as I don't want to break the bank.

I thought the front sway was significantly thicker than the rear - something like 22mm front and 17mm rear. I could be wrong on the numbers, but I do recall the front being much much larger than the rear.

Yes, stock is bigger and the car under-steers as is so if upgrading most people (including myself) would get a bigger rear bar so the car is more neutral to taily.

There is nothing wrong with an intake and no tune. I've been running an Agency Power short ram intake for many miles now no problems.

So far the only thing we have for the 09 FXT is our intake. Waiting for the Swift Springs to give it a nice drop and better handling.

I don't think that's something you want to give advice about. Your one example for "many miles" doesn't show anything. With an aftermarket intake and NO tune your A/F ratio's will be off and you will often be running LEAN which is very detremental to the life of your car. I worked in a Subaru tuning shop for three years and saw MULTIPLE cars with only an intake as a mod the destroyed their motors.

He MIGHT not be lean, but you definitely want to watch your fuel trims. It is all based on the flow and the size on the intake pipe where the MAF sits. If the new pipe is smaller, you will run rich, if the new pipe is larger, you will run lean. Yes, the ecu will adjust your fuel trims to help compensate for the change, but the ecu can only go so far. Then how the air flows through the pipe will also effect your fuels trims. Sometimes flow has a larger effect than the diameter of the pipe. Besides, slapping a intake (short ram = hot air intake) is a waste. What these motors need is to get the air out quicker, which means a better downpipe and CBE.

I concur. But I would put money on him being lean.

So has anyone ripped into the 09 yet?? I am looking for information and there is little to nothing out there. I really don't want to invent the wheel again like I did with my WRX. Anyplace to get any good info?? The forester forms have very little about the 09.

What kind of info are you looking for Russ? As soon as I hit 1500kms I will have my car up to Rocket Rally for a downpipe and tune and a once over to see what the following steps should/will be.

It shares almost all its parts with other cars in the Subaru family so it's not like we are breaking new ground.

This doesn't show anything either. Let's see some logs to prove dangerously lean AFRs w/ an after market intake.

Leaning out AFRs and running lean are two very different things.

Why NOT to run an intake without EM:

you will be lucky if an intake nets you any gains at all WITHOUT tuning. this is just because of the way it affects the cars. Certain magazines that have "dyno comparisons" of intakes before and after dont let the car learn to that intake (and hence they run lean for the pull) and thus net the "huge gains" of 3-5hp (which you would gain anyways if you leaned it out the same amount with the stock intake). Also, 90%, no, make that 95%, of the intakes out there are "hot air intakes" despite all the body cladding attempts to make them "cold air intakes". If you have one that truly runs the same Air Fuel as the stocker, and increases flow, and isn't a hot air intake, then yes, you can have gains without tuning. However there are only 2 or 3 on the market that do that. The gains will all be less than 5% without tuning, more like 3% if that.

If you data log the air temp on the intake, you will see clearly that some intakes are "hot air" intakes. On a stock tune the hot air intake can zap a lot ofnpower as the stock ECu starts to pull timing when it sees 40C on the MAF (if you think that is high, check the temps that the MAF thinks its seeing out on a certain "big" intake while you sit at a stop light. It would make you shudder).

But if you are maxing the MAF then an intake will instantly increase your output safely. Most people get intakes because they are maxing out the MAF, or have "completed" their mods and want every last bit out of it, or want a true cold air intake. Of course, those are the functional reasons. Normally, its a "low cost" item which can produce gains, if tuned for. I dunno. I once bought one for my RS because I didn't know what else I could buy for $350 that made me feel good :-) (Posted by Patr - aka PAtrick Richard, Canadian Champion Rally Driver and Subie Tuner.

I can search for more info if you'd like or you could show me some info that proves this false asides from a dude who says his engine is ok.

um that is the wrong intake we have a 2009 FXT which means it needs to be the 08/09 WRX/STi intake.

this link:
http://www.agency-power.com/catalog/...8-p-47972.html

we live at 1 mile above sea level so the AFR is different up here. Less Oxygen sucks up here, with the intake we might actually be helping our AFR. Plus we haven't gotten any CEL for the MAF. I know we're not netting any gains but tons of people have run an intake whether it be AP, Perrin, COBB, and whatever else is out there. I won't be running just the intake for long I hope for Stage 2 in the FXT in the next few months.

Also we've only been running this intake through the winter so the outside air temp has been rather cold. Maybe before summer comes I should toss the stock box on or maybe I'll just leave it on. IDK yet.

meh I've had no issues since we have lack of oxygen up here anyway. It might still not be good but oh well warranties are good for something.

At the very least I would grab a scan tool and check your fuel trims to see what they are doing. You you have the short term and long term pegged at 25%, you are on your way to major problems. If they are within +-5%, you are better. I still wouldn't trust it until you have a wbo2 on it to see what is really coming out of the tailpipe. There must be some local suby guys that have a scan tool and wbo2.

So does anyone know what turbo is in the 09 fxt?? I haven't had a chance to pull everything apart to check it out yet.

still a TD04 just now it bolts up like a Legacy GT same power the 2008 and prior WRX and older FXTs have. I think we can swap on the LGT turbo for a little power boost or even the 2009 WRX turbo for even more boost.

So does any company make an exhaust for the 09 FXT (twin exit) or would it have to be custom fabbed??

SPT has one, I think there is a post on here about it and some youtube clips.

A 10 second search got me this - http://www.youtube.com/watch?v=05PV5bORjJE
