GR Yaris & GR Corolla G16E Tuning Guide - From Stock to over 500hp.

After a year of development with our GR Yaris, we have put together this tuning guide for the G16E-GTS engine in the GR Yaris and GR Corolla. We took ours from stock to over 500hp and 10--second passes, which gave us, and Powertune Australia, the knowledge you need to build your GR Yaris or Corolla up to the same point.

Pro tip from one of the guys racing a GR Yaris (Rotheli racing I believe), the rear section of the exhaust getting very hot can cause the 4WD overheating issue, with a couple of bucks on some decent quality exhaust tape you can wrap the section around where the 4WD clutchpack and rear diff are - when he did that he didn't have a single overheat issue afterwards. When I install my new exhaust I will definately wrap the back of the center pipe.

[@smellyfish36]

As a new GRY owner looking to modify I loved every minute of this video! So much information in 30 minutes and I now feel empowered into making mine just as good. Thanks for your time making this great video 🙌

[@andrewlangford88]

Great you talked about the failures. This has been something that people don't want to talk about, making everyone think they're invincible. I'd be keen to know more about those cases of failure, eg. What power, torque, how bad the knock was etc.

[@boostgoober7262]

Yeah, when you modify them. In stocks trim, they probably are bulletproof.

[@R00567]

Toyota has engineered quite the engine from hell that can take a lot of abuse. Great work and really love the informative technical dive from the tuner as well as Andrew. You guys rock!

[@gwot]

[@hamishahern2055]

@@gwot has anyone taken the block to 750whp yet? if the GR was sleeved would it handle 1000whp like the Mitsubishi Evo 10 4cyl did?

[@midlifeparty]

​@@hamishahern2055that's a hail mary I believe. I worry about the stock components on the engine and transmission.

[@konforzone]

3 cylinder engine holding 500hp with little mods is simply amazing. I was suspicious when i heard the rumor gr86 will have this engine. However, right now, i am excited to see this engine on gr86.

[@garrettchapman8170]

Fyi motec isn't a little upgrade.. Probably costs 5 grand

[@tristenmarshall2954]

@@garrettchapman8170 I was about to say that seems like a lot of expensive stuff to be classified as "little" mods, I mean you pointed out the expensive ecu (6.5k), but you also need cams (1k), and turbo upgrades (7k), and a custom fueling system (~3k), full exhaust (3.5K), intercooler (750-1k), valve springs (500), clutch (2-3k). So erroring on the cheaper side you still end up at 23.5k in mods; really doesn't seem so little anymore.

[@darrengarcia4937]

I guess you dont look at offroading very often considering people have been tuning 3cyls to well over this.

[@Booneboarder]

I'm shooting for 350hp. I'd be happy with that. Don't need anything more. Hoping people here in the USA or other countries will get to unlocking the stock ECU. Not dropping 6K for an extra 50hp.

[@nicholasblack829]

These things are wild, can't wait for the GR Corolla!

[@venners4288]

Pretty good, when you put it in context. Double the cubes, double the cyls, and you get a 3.2L, 6 cylinder, that will produce north of 1000hp with equivalent mods. Correct me if I'm wrong on those specs. Either way, pretty good.

[@kaloyancholakov3725]

In theory yes, but that's not the main goal because they can fit this little engine in every car, also it comply with regulations, for the relatively small car 300hp is more than enough for most people and also cheaper to produce than the bigger engine. 1000 hp will require more hardcore components which will make the car more expensive and also will turn this vehicle into a very dangerous machine to drive. From a mechanical and technical point of view - the engineers could probably make even this engine double or triple the hp, but it will be 10-20 times more expensive to make it reliable and safe to drive. But yeah, I agree with you, the architecture of the engine seems to be powerful and well engineered.

[@geoffmcheyzer9821]

I've tried to tell people that "cracked" ecu does not mean they have full control over it. It's basicly a hack job at this point, same as "tuning box".

[@woznaldo]

Great summary of your development journey! I did have a couple of questions though. When does the stock turbo max out? What duration Kelford cam did you use and what benefits would there be to using more duration?

[@Robertfyfe62]

Thanks for all the videos and information, it's been extremely thorough. it would be interesting to know how much all that cost. i realise you were given many parts to test. i'm going to buy a Yaris Rallye and checked out the Motec cost- $6k plus fitting and tuning. Probably cant get that one past the wife!

[@RandomlnternetGuy]

Smart to get on this before the GR Corolla comes out. The enthusiast comunity will have a lot of questions

[@dj4monie]

Lots of dumb questions too and won't reference anything but keep asking the same question over and over again.

[@RandomlnternetGuy]

@@dj4monie people get into things at different times. It's best not to discourage people from asking questions and simply point them to information resources like forums related to their car.

[@dj4monie]

@@RandomlnternetGuy I'm not sure about that people are still doing the intake, exhaust, intercooler, tune thing without understanding anything. I don't discourage, I give them links I expect them to read or watch a video. If it takes Gale Banks two hours to get his point across then you better sit your ass down and watch it, he won't be with us much longer and we'll be worse off for it. These DI Turbocharged cars are pretty much dummy proof. Also no mention of spark plugs here but that is often debated as if this is the 1990's all over again. People should do their research before buying anything especially cars, all of them are reliable some more than others but the spread between makes is less than 5% and don't get me started on overpaying for cars.

[@DiegoFaustino68]

The insconsistancy on dyno with stock ecu its because the rear diff is lightly faster than front , the awd dyno gets crazy .. i take off the cardan shaft from mine and all the runs was consistent ( only fwd ) kzbin.info/www/bejne/rWTVamSOe86IpJYsi=Vg6sY1imYxReHUZj

[@PostMortemor]

I'm impressed by the stock ECU logic and how complicated it is and how hard it tries to preserve the health of the engine. Is there anybody in the German industry that has the same approach?

[@zaarkeru3391]

Oh yeah, this isnt some japan only ideology. The germans have done this for atleast a decade now.

I'm glad we are getting the Corolla GR instead in the US.. I want it bad.. I want to get the Base model and order it with the LS on the front and back.. And from there pay it off and by then there will be a ton of aftermarket parts and Tunes to make a safe 400 HP.. that would be more than fast enough for me..

[@marksafwet]

Guys … u r amazing ❤️🔥

[@Drunk3nMas7er]

Block insert = no water around the combustion area of the open deck, which is why they were created and is the major advantage of them... Yaris going to have open deck honda issues at big HP... Grout or epoxy on a late model engine seems naughty :P Darton on the case already I bet...

Hey guys great video! I'm modding up a GR Corolla and will be doing intake, manifold, downpipe, catback exhaust & HKS BOV as well as tune with the valvesprings and camshaft. Would I be okay with a 267-A model cam or would I need the 267-EZP? Cheers in advance!

[@MrTroytroy]

Excellent informative overview. 👍 For the Euro car guys - translation: Stage 1 = ~40hp for $10,000 🤪 Stage 2= ~80hp for $18.000 Stage 2+ = ~100hp for $22,000 Stage 3 = lots for lots

[@dj4monie]

Why would it cost that much?

[@MrTroytroy]

@@dj4monie Motec and custom tuning ain't cheap. Kelford cams and springs are $2k without labour and custom tuning. Overall one of the more expensive cars to mod (mainly because it’s so new and OTS tuning is in its infancy.

I'd be waiting for a lot more development for reflashing the stock ECU's to be done first before I'd consider reflashing the stock ECU unless you don't mind being a guinea pig. For stage one I'd look at a tuning box like a DTUK stage 2, that is proven to work rather than an exhaust.
