Safest way to get 15%-20% more NA HP and torque vs. stock
 

Let's assume I have a stock BRZ and a few grands to burn. What are my options?

As far as I am aware no one has gotten to 200 WHP NA without corn juice. I could be wrong by now.

I would start with a tune and headers though, those seem to be getting the best results.

Ecutek is your best bet with headers and perhaps costless.

Tap'd via G-Note2...

~160 whp * 1.2 = 192 whp. <== Is this your goal?

E85 tune would get you there. A tune and PTuning's water/meth injection kit would probably be enough if you don't have E85. Nameless header dynos look to be in that range, but they aren't finished the development yet. The Nameless overpipe and cat back might do it. The 'cold' air intakes don't seem to add anything other then driveability issues so I wouldn't bother with that.

The Innovate super charger might be enough to get you there, but finding evidence of bigfoot is probably easier then buying a finished one.

I didn't think of that! Have you seen this on an NA car? I just read about it on the @ptuning turbo kit a few days ago.

No, but it's the only WMI kit I'm aware of. If they can get a throttle switch to work there's no reason it couldn't allow some more power to be found with a decent tuner. Well, no reason I know of.

+1 for headers and tune. Throw in a catback while your at it too. It's actually what i'm going for.

My mods: headerexit back exhaust from nameless performance, Perrin Silicone inlet tube, Perrin drop in filter, Perrin LWCP, Resinator delete in the stock air box, and running 17x8 45 PF01's. (17.8lb each wrapped in hankook 235/45/17 V12's)

^ This made 169HP. After BRZedit protune at PREracing I'm sitting at 185WHP

Crapy picture but it is what it is. i'll get a print out and scan it soon.

Have the RevWorks header coming my way in the mail and have a retune scheduled for may 3rd. We plan to see a 10-15WHP gain and the torque dip to be eliminated. I'll post results after the header. (hopefully break 200WHP)

*edit* this is also on pump gas... non of that E85 BS

On E85? Yeah. On pump? Doubtful. I'll let you know when I get my next dyno; baseline was just the axleback and now I have the combo front pipe.

Borla header, stock overpipe, test pipe, ISIS exhaust, visconti tune, stock intake I made just shy of 180whp based on Phastek's dynojet.

I figure with an intake, overpipe, and updated tune I could touch 190 on the same dyno.

That thing is mythical though :iono:

Vortech SC with a 6 psi pully...220-ish whp. Very safe, quiet...and fun.

Thank you.
I don't want the inconvenience of E85. I'm looking for something that is as simple to live with as the stock but has more power.
Should I just look into a supercharger?

What would a full exhaust system replacement + headers + tune cost and how much you are hoping to gain in performance?

This seems to be quite an extensive job but you are getting some good numbers. How much did all this go for (minus the wheels and tires)?

I'm at 171whp on a dyno dynamics with the Perrin intake, Nameless overpipe, and Nameless axle back with no tune. With a tune and Nameless headers when they are released, based on what they've seen on a dyno, it should put me over 200whp. Overpipe/axle back $1100, intake $300, headers $1200, tune $500, so $3100ish for just over 200whp (more on a less restrictive dyno).

Spray.

+1

Keeping an eye out for headers myself, although I'm planning on going forced induction later down the road.

Nameless' dyno of the new headers look good, but its still yet to be released - and its been a while. I know when I was first looking at Vortech (before they released the kit) Nameless was still working their magic. Now there's the upgraded Vortech kit, ptuning kit, fa20club turbo, and some other turbos popping up. Seems like forced induction is the way to go if you want power with this engine - highest numbers I've seen N/A ~205whp with e85 and full exhaust/intake.

I'm also waiting out on cams as well. Hoping with a set of cams and headers this car will really start screaming N/A. But that's going to take a while it seems...

EDIT: Check out e85prices.com - looks like there's quite a bit of corn juice in your area OP. Worth a thought. I'm going to be going e85 for sure before forced induction hoping that'll wet my appetite until I can afford the big bucks ;)

ABSOLUTELY!! :clap:

Hate to say it, but a few grand isn't enough for this car to get ~200rwhp with new developing parts and a competitive market.

Id suggest

RevWorks header $700 Nameless frontpipe/overpipe + axelback is $1100 + Perrin Silicone inlet tube $120 and drop in filter $60.

Thats basically $2000 and everything above is self install friendly

Then find a local tuner to give you a protune on a non license E flash BS.

BRZedit protune $500 bucks

Thats $2500 and I guarantee you will be over 190WHP /thread

Fixed that for ya.

I hit 203hp/162tq, with AFE, SRT, and Visconti E85 tune. lol. I think it was like 186-188 on 93. I think with a good header, it should be pretty close.

hi i would like to know if i cut all the catalytic converters out and put a straight pipe,what would happen would it run better? would it hurt the motor? is it safe to do?

I'd be satisfied with 190whp. That's about 15% more than stock. Of course 200 would be nice. I think I can wait if the parts are still in development.

no ones hit 200 whp na statside yet? bummer man. plenty of 215ish whp tunes over here in japan.

Better gas over there, if your not counting corn juice.

Guaranteed 190whp
 

I currently have an AFE takeda intake and Perrin lightweight crank pulley.

Plan to put perrin headerback and either John's tune or Stage 2 Ecutek tune. And get 17 inch ENKEI lightweight racing wheels (13.1lbs per wheel)

Will guarantee a 190whp.

AFE takeda intake - 300
crank pulley - 80
Headerback - 1500
Tune - 800

2680 bucks for a guaranteed 190whp, if not more. But then again, your halfway to a turbo kit........

What mods are you guys running besides better gas?

DO TELL! :bow:

Same mods as us, just better pump gas, our corn juice dominates though.

In Japan, they have 102RON, 100RON, 98RON and 95RON which are respectively 97 AKI, 95 AKI, 93AKI, 91AKI. So the higher the octane rating, the more power they can be extracted if the engine is suited for the higher octanes.

So the Japanese Spec Toyota 86/Subaru BRZ's engines run on a MINIMUM 98RON (93AKI). Same as here in Australia, our Australian spec 86/BRZ are the same as Japanese Spec, except very slightly less tuned. Because we dont have 102RON fuel, we only have 100RON (at certain servos), 98 RON, 95 RON and 91RON.

Plenty of us hit 200 whp with E85.. on just a "few grand" too. :D

Sorry, no E85 where I live.

Mods ?

Since the torque did is gone, I'm gonna assume, header, catback +e85

CAI, 4-1 Header, over pipe & front pipe (catless, but resonated), and E85 reflash/tune.. cat-back exhaust is still STOCK. All parts & tune bought from & installed by @FA20Club.com :thumbsup:

I have yet to play with e85. I was behind a cop this morning with a FlexFuel emblem and I started smelling what literally smelled like burnt popcorn. I wasn't expecting that. Is that normal, or was he just pig ass rich on the tune? (oops accidental pun haha)

Not sure if burnt popcorn smell is normal for E85, but on my car, it's a kinda sweet-ish smell.. similar to coolant. I've never really smelt it from the exhaust though.. I have a breather filter on the hose that used to go into the intake pipe, so the smell comes through from the engine bay alittle.. mostly when I first start up the car.

I hate to be rude but where are you in Maryland that you can't get E85? There's a dozen E85 pumps in your itty bitty state.

Have you tried this map?

Yes. It can smell like someone is cooking french fries, popcorn, or even vegetable(it's corn!) oil.
