Has anyone out there gotten a meaningful amount of increased torque/horsepower from the new motor with simple bolt ons?

I鈥檇 worry about the transmission at a certain point but wondering if there is 10-25 more horses out there to be found.

We really do need a turbo next generation!

There are lots and lots of posts here asking the same question. The consensus seems to be that there's not much you can do without a turbo. Maybe a couple of horses but not 10-25.

Little to no possibilities. You'd be better of lurking at Forester or Legacy forums, the FB25D is their engine by default. But given that it's the same block as the FB20D and that even port-injected versions weren't particularly prone to tuning, there isn't anything really worth the money that would yield noticeable results. Someone dyno'd a few lbs.ft/hp increase when they ripped off their carbon intake filter. You could also look for a tuner who'd make a custom map for a higher-octane gas.

Buy a WRX and lift it. You get the engine and hood scoop you want. You lose the hatch for a trunk.

K&N sticker adds about 5 BHP. A custom wheel flame paint job about 10 but looks way faster than it suggests.
farty exhaust might give you a slight poot

Which leads to the next question, would it pass emissions inspections?
It would depend on the state. California has very strict, probably the strictest, emission controls. The fact that they have that disclaimer probably means they know it could cause emission testing issues. How many people buy a Crosstrek and never use it on a public road?

Probably.
And of course, not all states do emissions inspections on cars. That sure doesn't happen up here ...

I think most states in the northeast have pretty strict emissions testing requirements, but probably not as stringent as California. There are a few states that have no vehicle inspections, period - TN for one. And in NJ, new cars are exempt from all inspections for the first 5 years.

It's actually eight years here before you have to get a smog certificate but you could still get in trouble before that for essentially tampering with emission control systems, if they found out.

Some states' extent of checking emission control systems is to check for trouble codes or recent resets. 8 years is a long time.

As far as tampering, unless you are visible blowing nasty stuff out your exhaust, you won't get caught unless a mechanic dimes you out.

Yeah, that surprised me when I looked it up. It's four years if there's a change of ownership. Not sure of the logic there?

The smog check also includes a tailpipe emission analysis. Smog check places are not allowed to also make repairs so, if it fails, you have to go somewhere else to have it repaired, then pay for a new test.

After I moved to MA and bought my first new car here, I was surprised to find out that the owner has to have the car inspected after purchase and then every year. In NJ, the new car dealer just slaps a sticker on and you're good for the first 5 years, then you only have to inspect every 2 years after that.
