Default 2018 Crosstrek

My girlfriend just bought a 2018 Crosstrek 6 speed, premium... I know it is basically an impreza. She is wanting a little more pick up out of it. I have a 2015 STI, she isn't looking for that kind of power.

Is anything transferable from the wrx? Are there any performance parts for the crosstrek? Ideally... she would like a short throw shifter, intake, semi quiet exhaust, anything that will help it get up a little faster to pull out into traffic and pass people of need be. She isn't a speed demon like a lot of us. And she loves her crosstrek, would just like a little more out of it. So please, no suggestions of trading it in for a wrx and such...

Thanks

Unlikely to be much support for her unfortunately.

The '18 has the newer version of the FB20, so a brand new engine combined with the already paper thin aftermarket support for the XV/Crosstrek, it's unlikely there are engine upgrades for her

And if you do upgrade the engine it's going to be a tough task finding someone to handle the engine management AKA tuning.

DId she think it was underpowered when she test drove it? Trade up for a wrx?

she didn't think it was underpowered when she drove it the first couple of days. She loved the look, got the cool khaki gray, we also have 2 great danes so she wanted something to be able to haul them around in. She won't be disappointed if she can't get anymore power, just curious. Long term... I plan to put a built block in my sti and playing with the idea of take the motor and transmission out of mine and putting it in her crosstrek and running it with the stock set up.

Intake and exhaust won't add any power outside of a placebo. Unless the exhaust is significantly lighter but that still won't be noticeable. And a very light exhaust usually means full titanium or a straight pipe. Neither tend to be quiet.

Shifter mods may not be a bad idea if it makes finding the gear you need quicker and easier.

Weight reduction? Yank the back seats and put in a floor for the pups. In all seriousness there's not much that can be done.

There's no chance the trans/driveline of the Crosstrek will be able to handle the power from an STI. Even if the EJ is only 300hp.

Get some light wheels and sportier tires. See if a tuner can work out a tune for 91 and squeeze a few more hp, then an intake and exhaust might actually help if tunning with 91

That 18 XV has direct injection and 12.5 to 1 compression - immense improvement over 17 and earlier. Not much you can do short of using higher octane. The ECM will squeeze out what it can but probably won't be noticeable with the drag those two dog's heads will cause sticking out the windows.
Just enjoy it as it is - put the money in the STI where you will be able to appreciate real bang for buck from upgrades.

We have a 2018 and we now run 93 octane. We were having pinging and hesitation for the first 2k miles. We have been running 93 for 1k and have documented better fuel economy and less hesitation at lights. It might be related to the engine breaking in, but for the minimal difference over the tank of gas it's worth it for us.

Edit: Side note. Keep an eye on the paint. Ours is having a huge issue with flaking. Well outside the normal road salt chipping normally seen in the area. I'm talking our doors, roof, hood, etc. Basically everywhere that isn't plastic is chipping and looks worse than my 185k mile 07. Waiting to hear back from Subaru to see what they are going to be doing for us.
