A90 Supra engines and parts diagrams (all) revealed!

[justbake]

Some kind of an Easter egg

Nobody ever talked about a sunroof, right? Can’t imagine how it should work / look like with this shape of the roof.

We haven't seen any mules with sunroofs, and there isnt a sunroof headliner in the parts diagrams. I dont even think it is possible with the double bubble roof.

This goes back to these diagrams listing parts that were used in mules (IE placeholder parts), and not production spec cars

The plot thickens... So everything we saw so far from the leaks can be taken with a grain of salt

The naysayers are certainly eating it up

Btw,

anyone know what this is "in bmw world"? (Center button)

http://www.realoem.com/bmw/enUS/showparts?id=DB43-USA---J29-BMW-Supra 40i&diagId=61_5881

It’s a button for the NOS, I am sure of it.

That makes sense.

New engine codename B58C30O1 for J29 Toyota Supra 40i from wikipedia
https://en.wikipedia.org/wiki/BMW_B58

I dont know why it was listed like this. The diagrams showed it was a B58B30C.

It has now been changed to B58B30O1. The author did not include a source so who knows why though

It's just imposible the X5 has the same basis as the supra.
So it's a motor based on the B58B30M1
Why?
See the collector

Whats confusing about the parts diagrams leak is that the cars we have seen have the traditional 6 port exhaust instead of the 2 port as shown.

I think the WIki article makes it even more confusing because it states the X5 as having the B58B30M1 when RealOem says it has the B58B30C.

To further expand this. Why does the Euro Z4 have the restricted version of high output engine when it makes the same power as the unrestricted 'middle' tier motor? I am assuming the middle tier motor exists because the water cooled exhaust is better for emissions, so why aren't they using it in the Euro Z4? If the middle tier motor has the same environmental impact as the restricted version of the high output motor, why even go through the effort in creating a new head and plumbing system to achieve the same outcome?

Where you have seen have the traditional 6 port exhaust in the supra?

interestingly, the engine in the A90 goodwood prototype doesn't have an integrated exhaust manifold. you can clearly see the cast steel runners for cylinder one and two.

I wonder if they do actually share different heads?? Because it certainly looks cast and not water-cooled here.

We can agree to disagree on what we see here but that doesn't take away from the naming conventions not making sense and the necessecity of this manifold if they high output engine has the same emissions benefit with the addition of a filter

I have already reply to this post "It may be just this part in red because view the angle have no can see the collector with this cylinder head."

We can agree to disagree on that, I am not here to argue about it.

I was just bringing up rhetorical questions on the development of these 2 separate heads

Indeed I find it as strange as you.
Surely have made the choice to improve a single engine of the B58 X5 to reduce costs.

I was looking for spoiler/wing as it's part of the FT1 design. I can't find it anyone?
