Engine upgrade options for 08 Outback H6

I'm thinking about upgrading my engine, but I'm not sure what I should do. What have you guys done and how was the performance increase? I'm not sure exactly what I am looking for, I just want to get a little more out of my car. I looked at sites like Rapter Superchargers, but those seem a little pricey for me. Are there any nice upgrade options for less, or do you really get what you pay for?

asked about here many times, this board has the most H6 people on it in the known universe:

tuning of the EZ30R, and of the 5EAT

@west_minist = ed of XRT is one tuner that does work with both of those particular things.

just need a tactrix, and a windows laptop.

that and adding and upgrading some adjustable suspension to plant and adjust the rear end better. (using 2003 era rear KYBs,

and whiteline or megan racing adjustable stuff).


? Want people to stop needing to ask what exact car you have? year -model -engine -trans here:

The engine itself is pretty staunch as is. I have an '08 H6 as well. I would suggest whiteline upgraded swaybars front and rear, plus rear rallitek overload springs, some upgraded brake pads, and definitely replace all your control arms front and rear. The bushings wear out and mess up the handling after >80k miles. I replaced the front control arms with spec B clones by mevotech. That plus replacing rear control arms and sways really transformed the car and made it feel faster. For horsepower increases you are looking at serious money. Easiest bang for buck is k+n air filter, synthetic oil, and less restrictive mufflers but still you may only get 10 hp more.

yes - get Ed to tune the engine and transmission. that's about the only thing worth considering.

otherwise if you want to actually make the car faster, it's a waste of time. NA engines don't respond to modifications like FI. read up about the differences if you don't understand why, it's physics driving this not parts/design/people. you'll spend hundreds on intake/exhaust and you won't notice it except worse gas mileage because you're just pushing the gas pedal harder trying to tell if it's faster.

if you just want to tinker and have fun and play with modifications that make a 0.05% difference - then pick what's fun to you - custom intake, custom exhaust, lightweight pulleys, undersized pulleys, get a 5 rib belt, remove your A/C, get lighter weight tires and wheels, vary your gearing with slightly different tire sizes for quicker acceleration, have your heads ported and polished if your headgaskets blow, then weight reduction by removing anything you can, drilling holes in bumper beams to reduce weight, buy a stand alone and program your own ECU, etc.

if you just want the novelty, looks, and to talk about it with friends - do whatever you want that sounds fun to talk about. it won't matter so the beauty is you can do whatever you want and get the same warm fuzzies about it. lol
