Default 2016 WRX Moaaa power help stage 3? E10?

Hey, havenít posted on here in a while.

Anyways I have a 2016 WRX Base that just hit 63k miles. Bought it brand new off the lot in APR 2016

Current mods are:
Cobb 91 Octane Stage 1 Tune
Mishimoto Intake
Turbo XS BOV
Axle back muffler deletes

I want to make some more power, maybe upgrading to stage 3 setup, FMIC & TGV/EGR delete.

I was also looking into flex fuel kits and of course upgrading my fuel pump & injectors as well but the only problem is that where Iím from, E85 isnít available. Really big disadvantage. Iím from Hawaii and the only ethanol content we have is pump gas E10 (At least the island I live on)
Would running E10 be even worth it?

Also whatís your recommendations on a nice & safe setup? Im not looking for crazy numbers. Iím only looking for 300whp and even if I can get close to that, Iíll be happy and I donít want to kill my motor getting there lol. Iím not too tight with budget.

Btw I have 4 years shop experience.

I was able to get 300whp 315wtq with TMIC, full tgv, egr, and jpipe after a protune. But I'm also running 93 oct. E10 is in all our gas here in PA, not many E85 stations either

OP- If you want to make safe power I would get rid of your intake and BOV and start fresh using Cobb's Stage2 or Stage3 kit with flex fuel if you have access to other fuels.

Otherwise I'd just keep it the way you have it if not encountering any issues. On my WRX I have the Cobb Stage1+ (includes their intake running 93oct) and Remark deletes. That is all for safe power, besides a BoombaRacing catch can. It's not a fast car by any means, but entertaining to drive as my daily driver/winter fun car.

Agree with all the above.

Step 1 - get rid of the BOV and Intake - still see mixed results even after "safe" tunes with those noise-makers

Step 2 - Full turboback exhaust, with EBCS, TGV/EGR, and TMIC/FMIC will definitely net some safe gains (HP numbers and butt-dyno).

FWIW - I bought my 16 wrx with 4 miles on it, went stg 2 at 40,000 (only catless turboback and EBCS) and am now currently at 120,000 miles with no issues at all. Definitely satisfied with the power gains from stock and I don't even have TGV/EGR deletes or TMIC/FMIC...

Nice, are you running stock filter or CAI? BOV?

Thanks for your advice.
I donít have any access to any other fuels which is why I was curious to ask if running a flex fuel kit with E10 would be even worth it.
I still have my stock BPV and intake so that shouldnít be a problem.
I was thinking of getting a j pipe and upgrading a few more things to get to stage 3 and a proper pro tune.

Thanks. I have my stock BPV and intake.
Would running a BOV cause a boost leak? Or just get rid of it for a useless noise? I kinda like that whistle sound lol. I donít care about my CAI, I wouldnít mind taking that noise off.

I was thinking of getting a Jpipe and upgrading a few more things to stage 3 with a pro tune.
Also of course servicing my tranny, diff, fresh plugs & oil and double check for any oil leaks before I get a pro tune, making sure my car is ready for the next step

OP, check out this mod path and suggested parts list. I had fellow members point me to this for information in the past when I owned my 15' wrx.



I believe most of it still stands true, and it was written by a reputable tuner, phatbotti.



15' + Suggested Parts: https://phatbottituning.com/2015%2B-wrx-suggested-parts


15' + Mod Path: https://phatbottituning.com/mod-path


Hope this helps , and gl!

Let me give you some more advice...keep your intake and bov, you paid for them use them...

Donít let people scare you away from anything..if tuned properly it will work normal,

Def get the j pipe and the full tgv delete from ibr..well worth the extra money and get a proper e tune for your mods, I can recommend one privately

Fwiw Iím running a 2015 wrx with full bolt on and a non recirculating hks ssqv all installed at around 58k miles and just ticked 81000 and not one single problem at all

Running 93 octane with 50/50 meth injection added recently and so far loving it cause e85 isnít avail where I live either! Look into meth injection for added power and cooling but with j pipe and tgv/egr you will get 300 whp with a good tune

Hope that helps

Thanks for the advice.
I was thinking of getting rid of my TurboXS BOV since I wanted an actual whistle sound lol and upgrading to HKS SSQV. Wish I never gotten rid of my old one that was sitting in the garage...
Is your setup FMIC?
I know a few things about 50/50 meth injection but not an expert. Scary thing to think about is water in the combustion chamber. Will definitely ask some buddies about it. Thatís my only concern.
Iím definitely going pro tune for more accuracy and being on the safe side.
Also I did mention that I have a stock exhaust with axle backs. Would it be better to run full exhaust from headers down to muffler or can I keep my axlebacks with J pipe?

Thanks for the link! Top link was 404 not found but the second link worked and had helpful information!

Advanced Setup Pump Gas sounds good. Doesnít need flex fuel kit/ethanol which is what Iím aiming for.
Also thinking about upgrading my radiator to an aluminum one for better cooling.
I want to stay in the $5-6K range.

I run a spt exhaust which flows about the same as the stock exhaust

Zero gain other than sound from a full cat back

And with meth injection itís such a fine mist that the water vaporizes almost instantly and the chamber is so hot it wonít condense back into a liquid

Itís mainly for cooling and octane boost for more timing

Thanks. I really donít care about changing up the whole exhaust if the only thing itís going to do is make more sound and not power.
Is the 50/50 meth & water mixed or does it run off two separate pumps?
Also what size reservoir do you have for the methane and how long does that last?

I would always run the 91oct pump gas with 10% ethanol, you donít need the flex fuel kit for such a low ethanol content. It will give you better knock protection and thereís no need for an upgraded fuel pump. Hereís a list of bolt on parts that should get you right around 300whp. Full TGV delete/ EGR delete. Upgraded top or front mount intercooler. A front mount will cost a bit more money and really isnít necessary for the power your looking for, unless of course you would like it for the look. Catted j-pipe (cat-less will most likely cause boost creep, which is not good) this will make your car pretty loud especially with your muffler deletes. A good cat back exhaust to pair up with the j-pipe wouldnít be a bad idea. EBCS (electronic boost control solenoid) obviously to control boost is better, also Iím pretty sure your tuner would highly recommend this. I would stick with proven name brand parts like IAG, Cobb, Grimmspeed, And some others. Do some research on reviews of parts and recommendations. These are all very popular mods as Iím sure a ton of WRX owners all have most of these installed.

Agreed !

To answer your meth question I run a 60/40 methanol to distilled water and have a 1 gallon tank and it lasts a decent while...it only comes on above 7 psi of boost so when your just driving itís off
