I would do supporting mods just to get them out of the way,, look for cylinder 4 cooling mod, and also a big radiator there’s nothing worse than a Subaru overheating. Or even an air oil separator.

I see no value in a "bigger radiator" -- the cooling volume in any turbo Subaru is much greater than anything you are going to throw at it with those modifications.

Firstly, are you CERTAIN that you want to throw away your factory warranty? It would be pretty awful to have to throw ~$10k at a BRAND NEW vehicle because of an engine failure. Any time you push the OEM components outside their factory envelope, you increase the risk of an expensive failure, never mind failures that are inevitable on a newer vehicle from manufacturing defects.

If you are OK with throwing away the warranty and are OK with spending ~$10k in order to recoup costs should a failure occur -- yes those mods look OK. I wouldn't bother with the FMIC. Instead spend the money on good brake pads and tires.

There has been nothing put forward about the cyl 4 mod that tells me that's anything besides hogwash. The uel headers of the ej are the biggest problem in my opinion.

I'd also avoid recommending modifications for someone's car if you are not aware of what you are suggesting. The cylinder 4 mod isn't even something for the fa20f in his wrx.

Personally i can't recommend against modifying a vehicle under warranty enough, and before someone makes the back to stock comment it's blatantly obvious a car has been modified and Subaru of america has the final say. You'll lose, look like an ass, and make it harder for legitimate persons to take care of actual problems.

Start small and build your way up. Don't buy everything at once. Start with a catback and enjoy the benefits of added sound for a while. After that, add piece-by-piece whatever is compatible with a Cobb off the shelf tune. This will give you plenty of time to do your homework and it will be easier on the wallet.

You honestly may get to a point where you're more satisfied than you had intended, earlier in the modding process. I had big plans for my 2015 STI, but then I realized how content I was with an intake, Cobb OTS tune, and exhaust. Now, with my current STI, I'm looking for a little more power, but that took me years of enjoying what I had.

I agree with what Zax said about brakes and tires. Paired with a good exhaust, it's going to change your experience in the car. Be patient and start slow.

Money if it “blows up” isn’t an issue.. not so worried about something going wrong while under “warranty”. Looking to get more bang for my buck. At minimum I would like an intake and a turbo back exhaust i can the state 2 a Cobb tune from the access port

You are looking at a substantial cost. Easily and I mean easily passing $10k, and depending on location possibly as much or more than 1/2 the cars value.

The fa20f responds better to modifications on the cold side if that matters. Intake, egr, tgv

Those were all part of my original mods I was looking at. Only thing I wanted to add was an AOS everyone recommends due to how the system currently works.

Aos can help but it's not a miracle system. Until the added oil content in the air starts messing with the knock rating of the fuel causing knock it's not super beneficial. The egr delete will be far better at keeping the oil and crap out of the cold side.

Dont be scared.. people have been modifying cars forever. Its always at SOME risk. Its all personal choices. “I” would do intake, catback exhaust. And if i wanted more, goto E85.

Thankfully no tuner on the planet would do that for you because its a piss poor path.

You'd need intake, egr and tgv deletes, turbo back, ebc and external wastegate, bigger fuel pump or lift pump if on the fa20f, and numerous other things before e85 should be a consideration.

I meant turboback not catback. And you dont need egr/tgv deletes. Going E85 implies all the prerequisites with it..

Hi I entirely agree with you. I am setting aside mod's and experiments for competition which is a different story. I'll extend you so-correct suggestions Prozach.

Why take a WRX of some value and turn it into something not only immediately devalued but of forever-more way less than market value by bolting on bits of ballast ,requiring a 'tune'... On a car still under warranty as was said by Prozach ...voiding your warranty ...but also voiding any insurance and any free service if some is still with your car....It makes no sense at all.

Why do it? ...to join the long line of other people the ego-exciting 'tack-on' Pied-Pipers who way back saw a market for vehicle fantasists?. Subaru had an entire team designing every element of your car with equipment so sophisticated people calling themselves 'tuners' will not have. Your car will have itself or 'the model' track tested and road tested so everything works together as a package which includes emission control required where you reside.

Most mods will sit there unused whilst the wallet skinned owner swans-around in the 'designer' car or attracting attention of the highway patrol. My first suggestion is that if you want something higher in performance but must be Subaru and seriously attention attracting sell your car and buy an STI in an earlier model. If not... at the time of replacing your present car's timing assembly and water pump cam seals etc...have the suspension totally checked, boots, rubbers, cracked and worn components replaced. Sump-off taken off and scoured clean, oil pump checked. Forget 'coil-overs' for road driving... Stay with the standard suspension style...which your car is not (I think) adjustable...but have a Bilstein specialist formulate the best sports setting Bilsteins after checking/replacing your tired springs. Don't get camber plates.....and if modifying camber the better way, check for ok with your insurance company.

Have your radiator scoured or replace it if not in really good shape . I'm not sure in your model whether the STI radiator is larger and with larger fans but if you want cooling improvement that's a harmless way to go but...any variation to your car can be used as an excuse for an insurer to void your insurance and/or Subaru to void your warranty.

Have your calipers completely reconditioned, of course fluids replaced...as should be every 12 months. Check transmission and replace clutch with a kit including rear oil seal, spigot bearing and surface machined flywheel. Check head for oil-leaks, read plugs for colour, check injectors for condition and fix all as needed, same attention to ignition, starter motor, relays. Check rims for ''true' and replace tyres with high quality type if not already done. Stick to safety.

I'm obviously suggesting work which holds or improves the value of your car....doing a partial rebuild for a new start. You now have a car of which you can be proud, feel reliability and is an attractive unit for sale.

Once ex-warranty it might be fun to try an original Subaru strut brace. If you want to lower the car for example...again reducing value and increasing circumspection of buyer or at trade-in then get a written 'ok' from your insurer or don't do it...Your car with only lowering by say and inch all around. You may shrug-off your own loss in a prang but the loss to any person car or utility will also not be insured so you will be chased for indemnity.

Bilsteins aside, general maintenance (e.g. tyres) all that will approximate for advantage about what you are planning to spend in devaluing your car. Appreciate what you have or buy an STI...but don't then engage in fantasy with it ...is my advice, look after what you have keep it safe and valuable. Voila

I don't understand why you associate owners wanting to make changes to the feel of their cars as egotistical, which you've made reference to before. If he puts an intake and a tune on his car, does that suddenly make him an arrogant toolbag or a showoff? It's possible he likes his car, but he'd also like a little more power. Or, he could want to get rid of the factory tune and associated rev-hang, of which I've seen well respected car reviews criticize.

There's little wrong with that as long as you understand the consequences. I also highly recommend having the car paid off and (or at least) have savings if something goes wrong.

You offered him little to no help, but I suppose he knows how to maintain a used STI now.
