Is Tuning the 2.4L BRZ/GR86 Worth While? ECUTEK tuning our Subaru BRZ - Motive Garage

[@benve_luca]

[@euphoric5172]

You should stick with a naturally aspirated build for this one, since this is the modern revival of the AE86 and the best 86's are tuned N/A builds, i would love to see if changing the whole intake manifold and intake filter system would make a good difference for power on this engine, could certainly get more power out of it at high RPM with an intake that's optimised for peak power, but E85 would be a great upgrade too.

Yes, NA power everything like the S2000.

If TOMS come out with Cam and Rod I be very interested. If it can rev out to 8k rpm and gain more HP at that top end will make this extraordinary.

[@Kami892]

idk maybe i don’t know what impressive gains are, but 15hp from a tune doesn’t sound crazy. my 2019 turbo brz was making more whp than this car on BASE map (5psi) after tune i’m around 290whp on 12psi, which was a 60hp gain from the tune. No E85 yet because there are no stations around me obviously you aren’t going to get as big gains on an NA car, but my point is, why spend 600-1000 on a tune when you can buy a turbo kit for 3-5k and have 3x better results and 10x better after tune.

[@idokwatcher2062]

Because it is illegal to put a turbo on an N/A car in most of the world.

[@andrewrigg4905]

Sounds quite good. Good gains .

[@boost331]

I will still bet a UEL will do better filling in that TQ dip and making power under 5k. The EL should still do better with peak numbers. I think a UEL will make for a more peppy, fun street car. And lets not forget that the sound is like an engine orgasm. You can keep your couple extra HP up top as far as I am concerned. LOL

[@racefix]

You can't feel the torque dip at all by the seat of your pants. The 4-2-1 header design mimics 90% the mid range gains of a UEL header while still being able to flow the HP up top and the engine stays motivated to rev.

[@boost331]

@@racefix I sure felt it when my car was stock. Now with my UEL the car will light the tires up from a rolling start when it hits the midrange. That is still on stock tune too. Im usually all about max performance but the sound of a UEL cant be beat. In this case I make the sacrifice. I am glad to see progress with tuning for sure though. Once flex fuel kits are available I will get mine tuned.

[@ChrisPlaysCoC]

@@boost331 I 100% have to agree with you there. I had PSR UEL headers on my GT86 paired with the Invidia N1 full exhaust and it sounded godly...

[@anothersome1whoknows]

Make you appreciate what was possible in the early 90s with the Porsche 944S2 and 968. 3L 4cyl N/A with pistons like coffee cans. Change injectors, plugs, cat delete and get ahold of the factory racing chip and presto, 310whp. They hung in there with 550HP Camaros and Eagle Talons running all the boost in GT racing because they had a wide power band with the vario-cam. V-Tech yo. 🤣🤣

[@ratty2012]

86s and metal? Two of my favorite things

[@spencersinger3209]

You guy should do a series with the VB WRX like you guy did with the Yaris…awesome stuff 👍

[@tone3560]

My objection is I bet the car bone stock dynoed higher then 152kw due to the full exhaust potentially flowing too well and the ecu in stock form not compensating which reduced hp from bone stock. So the real net gain from bone stock vs full exhaust +tune isnt as substantial that is shown in this video on pump gas. What do you think?

[@frank_lotion_]

It’s intended to be a more “pure” car, not a drift missile or a rally machine. With that kind of driver’s car approach, NA is really the best way to go with that setup, notably for the linear torque curve and predictable power delivery. That 3 cyl turbo prob would have made the car unwieldy and ornery, which kills the whole point of what the GR86 is supposed to be about in the first place

[@HardstylePete]

[@avery4528]

There’s no way that power plant is lighter considering all the added engine support to run a turbo system.

Is the WRX a better candidate for power? Doesn't look like a sports car though; it looks like a Tonka toy nowadays. It needs plastic conditioner in the sun over time. lol. I'm wondering what it can do with forced induction, cost to add that, but this 15 hp is so underwhelming. I'm looking into the tuning potential of these for power, then add a wide body kit, and some light rims + wide tires.

[@jameslovett8697]

16wkw increase, how many wnm?

[@Blight-fp3vt]

So 16kw (11%) gain from tune and headerback exhaust system on 98. Potentially 27kw (18%) from stock to e85. Really good for what, 4k in tune and exhaust stuff? Just another reason why you should get the manual BRZ over the manual GR86, which is 4-5k more expensive her in Aus :( And while I am here. 176kw at the hubs from a 4 banger naturally aspirated?

[@Treaxvour]

Kevin Vo did e85 tune with the ecutek beta. The new model has multi-injection - direct injection with port injection. So it should clean the valves from the sticky build up that is common on high ethanol gas. However, the power gains are not much. Kevin made 6 hp on e85 compared to regular gas, with an exhaust and tune. For a naturally aspirated 4 cylinder, I don't think the power gain is worth the fuel economy. And I live in the state with the most abundant ethanol in the country.

It has reportedly "fixed" the issues with the older engine so reliability is a bit unknown at this point but said to be better.
