Default Proud owner of an r-title Impreza

Hello, I am glad I found the NASIOC forums.

I bought an r-title'd 2015 Subaru Impreza hatchback. I originally wasn't planning to modify it too much but... I've caught the bug.

The first thing I want to do is see if I can find a hood with a scoop. I have having trouble figuring out which hoods will fit my car exactly though... As far as I can tell, the 2015 Impreza never came with an OEM scoop hood. I have found a few WRX hoods on eBay that "say" they fit my car, but I have no idea how to make sure they fit.

And no, I don't care how "rice" it looks. I do want the hood for the looks right now. I plan to eventually turbo the thing. Since it is an r-title I basically own it until the wheels fall off. So in another 100,000 miles I'll add the turbo to keep the performance up.

Now I have heard that an open, non-turbo'd scoop hole actually lowers performance a little (drag) but also by lowering the under the hood atmosphere which can be bad for the engine? So I was thinking I would machine my own hood delete and fasten it right under the scoop.

Anyways, I would really like some help figuring out what hoods might fit my car since I am having trouble elsewhere. Like do 2015 Impreza hoods swap with 2015 WRX hoods?

Thanks!

I don't know that any scooped hood fits your Impreza. If you do add one, it won't hurt your engine if it's open. It will indeed reduce the underhood temps, which is good but it also increases underhood pressure, so it very slightly lifts the front of the car up. My wild ass guess is it won't lift it more than a mm. Of course, this also reduces slightly the amount of air coming through your radiator. Again, a rounding error amount.

As far as turbo'ing your engine.....so are you planning to replace your piston with low compression pistons to properly set it up? If not, enjoy the 500 miles of turbo-ness before you blow the crap out of your engine.

For your own peace of mind, you should research why your car is r-titled. The best case is a recovered theft where the car was stolen, paid off, then found. The worst case if flood from a southern state where nothing is required to put the car back on the road. These cars show latent problems years later when electrical gremlins creep in and everything goes to crap.

Yeah, I'm not sure. eBay seems to say that there are a bunch that fit my make but I have no experience in this area. I have never had money to mess with a car before and I would really like to try to get a hood with a scoop. I just think it would look so cool, rice or not.

Thanks for the reply. So turbo'ing seems like more work than it is worth? I don't want to hurt my engine.
As for the r-title, it was totaled with 11,000 miles in New York state, bought in an auction and fixed in Ohio. there was little damage, no frame stuff at all. The stock alloy wheels are scratched up from the wreck but other than that its fine.

I would post a few links to the hoods I am watching on eBay but I know some forums frown on that kinda thing.

I was afraid of getting responses like this. I guess I'll abandon the idea.

if I was stuck with a regular impreza and wanted to mod it I would probably go the off road poser route lifted with bigger tires and small rims.

Interesting take. I was more in line with the idea of a scoop. I just thought it would look really really cool on the '15 Impreza. I think I found a place that will do carbon fiber hoods but that is a bit more than I was planning on spending. And besides I'd rather paint it to match the car...

After doing a little more reading it looks like I should get an intake filter and a muffler. After that, the rally armor mud flaps look really cool too.

Just because some people want to respond in a way that is not what you want shouldn't stop you from going after what you like. In the end it's not anyone elses car but yours, if you want a scoop then get one, who cares what others say? You're the one who will enjoy it. I found a .. not cheap option on CarID. I would honestly look at hood scoops and see if you can get a shop to fabricate a hole in the hood and you install the hoodscoop, you could also try to see if a same year WRX hood would fit, i'm not sure if it does but you may need to modify it slightly to fit, this could be your best option as far budget. Don't be swayed by other people, please. It's your car and you do what you want with it.

Thank you.

After doing more research, still none has been conclusive, I honestly do not think that they make 2015 Impreza hoods with scoop options. If they do in fact fit, I don't think the WRX hoods reach all the way to the grill on an Impreza. but if you can replace the front bumper/grill assembly with a WRX assembly it might work.

what is the end goal for the car? if you want to alter the looks of it, that's your call... but an air filter and muffler are not going to add power. with an N/A subaru, bolt on "power" mods might add a bit of oomph at a specific RPM range, but you're not truly adding to the total HP output. you don't start adding N/A power until you start replacing engine internals... even then, it takes BIG money for mediocre increases.

years ago i had an '02 OBS, which I added .040" over hi-compression pistons, STi crank and connecting rods, Delta 1500 cams, ported and polished heads, light weight fly wheel, blah blah blah. it made it pretty fun, but was pretty expensive and ultimately a waste of money. the best mod I did to it was trade it in for a WRX. hahaha honestly, the best bolt-on power mod I did to the car was a light weight crank pulley.

stick to suspension mods, bushings, lighter wheels, better tires, better brake fluid and stainless lines, etc.

those stock wheels are heavy!! my wife has a 2012 impreza sport. when I throw on her winter wheels (16lb 16" 02-05 WRX wheels) it makes a HUGE improvement to acceleration.


any 08+ STi rear sway bar will fit your car. I have a 19mm 2010-2014 STi rear swaybar on my wife's 2012. HUGE handling improvement over the 16mm stock bar. also, 2015+ STi rear sway bar is 20mm... i had one of those on my old 08 wrx...

and no, there is no factory hood scoop option that will just slap on there. since 2011, the WRX is no longer a tarted up impreza; it is much more of it's own car.

So much of this post is extremely helpful, thank you. Not that the rest of the posts here haven't been, but this one brings me the most clarity. I guess I hadn't thought much about the end goal, and it helps to hear that it is ultimately a money pit. So Bolt on power isn't really the way to go. In the same vein, can you explain to a complete newbie what an air intake filter and muffler would do for my car?

Yeah I keep hearing about sway bars, so I should look into getting a bigger one? So again, what exactly does that do for me? I seriously know next to nothing about this whole Soobie stuff. And other lightweight modifications... cool!

Yeah It seems like the Impreza and WRX are pretty far from each other despite them still being called "Impreza WRX" all over the internet. I guess maybe my end goal will be to trade up for a WRX eventually. Seriously they look sick as hell. Anyways... Well I will probably stick with exterior mods and maybe replacing some of the heavier pieces.

Thank you!
