GR Yaris (Gen 2) GR Yaris Mk2 (MY2024->)

It was in for brake line fitting and exhaust development. Mods wise, it has an Eventuri intake, enlarged piping to turbo, Airtec inlet manifold, oil cooler, intercooler, torque mount header tank and so on.

My goal is 350-400bhp then suspension. Tuning wise EcuTek are currently working with Litchfield on the Gen 2 so something should be coming our way.

Oh nice! Did you modify your mk1? Will be interesting to see the comparison data from the likes of Litchfield of mk1 to mk2 with similar mods.

I can only assume, the gen 1 didn’t have anything either from what I can remember.

I think so too, but I said to myself: if they put 2 flanges in the mk2, could it be that they noticed something? then I noticed that whoever mounted the muffler changed the bolts and compressed the springs a lot, not totally, but more than the original ones... I don't know if I should unscrew them a bit... or leave them like that because it won't move anyway

For what it’s worth, Akropovic tighten the ‘spring bolts/nuts’ to 34NM.

MyT is old and depreciated, MyToyota is the new one that is updated, what is not working for you ?

And anyway, i am not talking about the app, either it is an Apple or Android phone, connect it through your car with bluetooth, enable carplay Android Auto if you wish, save that phone under your user profile in the car, and that splash screen with the choice will dissapear.

Here you go !

Got it too work now! Thank you again 👍🏻

This is no mapping just with the bolt ons?

Correct just Eventuri intake, Airtec inlet manifold and enlarged silicon piping to turbo from intake.

I would have expected a bit more given the Japanese cars have 300 stock. I suppose you have the gpf still in place?

That was bang on where I was expecting. They are 276bhp stock on non-JDM cars. And Eventuri is reported 12-15bhp, so 9-12bhp from the inlet manifold which is around what I have read elsewhere.

And yes stock exhaust system with GPF, I think with exhaust, GPF removal and a remap which EcuTek are working on 350bhp should easily be achievable.

Is yours the one in the latest vid shared by Paul? A piddly 291 according to that. Or do you mean 300PS rounded up? 😉 either way that’s good gains from just bolt on hardware and leaves plenty of headway for when the ECU has been properly understood and tinkered with. Be interesting to see if a TCU tune will be forthcoming as well. I do love that grey colour 😊👍

Good numbers for bolt ons only.

I imagine your target should be easily achievable with a map and opening up the exhaust. Sports cat too?

Yeah just seen. He said 300 yesterday guessing he rounded up 🤣 so basically all air intake. Before anyone comments ignore the temp gauge.

Yeah I suspect all of that is probably the intake although since the inlet manifold and turbo piping it feels more eager to rev which is good.

I have looked into HJS sports cat but it’s not compatible at present. Think they’re working on it.

It’s nigh on 300PS anyway and those are solid numbers for just hardware. Despite its high price point the Eventuri certainly backs up its power claims. That and a HJS cat on my Mk1 produced terrific gains outside of a remap.

why in the description of the hks exhausts it says: Not compatible with vehicles with 17-inch wheels or rear constant speed differentials??? the circuit or high performance have LSD so they are not suitable?

Honestly I don't understand this today news by Toyota Europe.
Further tiny improvements the GRY, while order books are closed for it almost anywhere?

That vertical handbrake is really a temptation to me, anyway... (still not enough to buy a new car, clearly 😬)

On Toyota global they're only talking about a japan release https://global.toyota/en/newsroom/toyota/42579162.html There's also more detail on the chassis modifications.
