B58/S58 will not be utilized in the production Supra, but they are being used in the mules.

That said, this 48v system is definitely possible :D
Thank you for the reply. I have a hard time believing that Toyota is making their own forced induction engine after being out of it for so long. Hopefully I'm wrong because I'd like to see more brands making a turbo inline 6, but the cost to dive into something like that is immense.

Perhaps they won't be called the B58TU/S58, but instead a new engine name using the same underlying technology with Toyota specific customizations. Kind of like how Microsoft orders their Xbox CPU and GPU from AMD, but get custom silicon to cater to their specific needs.

Another explanation for this comment, is that we will see something like the B48TU in some of these lower models for the first production Supras with the other motors rolling out later?

I don't really even care about the B58, but an S58 class engine is what I'd be most interested in, and its what I am trying to push for. I think it would be a pretty big fail if they don't produce an RZ/GZ tier Supra to compete with the S58 which we will likely find in the G29 Z4 M.

Lots of other magazines say that there is a Supra GR, GRMN, GRMN Sport version that would work like a Lexus RC, RC Sport and F line.

So there will be a RZ/GZ teir potentially.

If not, there ar emods that can be implemented like a sport package to make a F tier car.

I agree, the B58's ECU has been cracked so getting 500whp out of it should be no problem at all by the time people have these in their hands. But this is a bit different than a true RZ/GZ trim. As someone who drives a 650whp N54, there is a lot to appreciate about the S55. A big difference will be the suspension geometry and handling. M cars almost always get out of the hole better, not to mention around the road course.

you may be extrapolating far more than what I was getting at... this is more like going to a manufacturer and saying I need something that will do this, this, and this. what do you have? oh, you don't have anything currently that will do that... well, can we use these and and modify them to work? Okay, lets do that.

so, it is bespoke, but it's still a collaboration for sure.

Considering my custom silicon analogy, I can agree with this being incredibly likely and if you're suggesting such a thing then it makes all the sense in the world. Thanks for clarification.

Put the people in charge of the Dodge Demon and Supra together in a room and piss them off. You might have a chance then :D
No need, quite a few people will be trying to slap a 76-82mm turbo, going for broke within a few months of release or swapping a 2jz lol.

Will need a stand alone that does Direct Injection. The N54 crowd had to wait for the Syvecs because of the piezo injectors, that really held that platform back big time. Only now are they actually beginning to see results from it.

Yea, I agree. My friend had those issues, with him doing a bigger single on his 335i. I'm sure there will be more people working to tune the Supra though, just because of its name, compared to what the 335i and such had. I was looking at running syvecs for my build, before I decided to go with motec.

I'm still banking on Toyota incorporating their D4S hybrid injection. I'm also hoping they will take it easy on ECU encryption, but that might be wishful thinking. Tada-San is still saying "tuner-friendly" so we'll see.

If its a BMW engine, it will likely be BMW engine control, which should be handled by the MG1. BMW locks down all their software because frankly that's where the big bucks can be spent.

If Toyota has a contribution to this project, its on the electric side, and I doubt a hybrid injection system would get implemented by BMW. It could, and I hope it does because that makes things simpler for us enthusiasts. BMW has quite a bit of money and test time on their high pressure pumps, which have evolved over time to include dual pumps as found on the S55. Bosch who makes those pumps even have higher capacity versions which you can custom order(for $5k+) from their Motorsports division, so with that type of head room I just don't see the need for PI.

Hey man, a set of ID2000s for a JZ costs $1500, and that's a much easier pill to swallow than $5k! But you're right, we'll just have to wait and see.

For all the the bad and good of the Subaru collaboration, at least Subie's ECUs are all unlocked and easy to tune. It's really an underrated feature!

All that being said, let's not forget that it took nearly 10 years for RR Racing to crack the ISF, so I guess it could be worse.
