I thought the B58 engines were all the same, including the one in the 2020 Supra.
Watching the Papadacis Racing video on YouTube (1000 hp build) it shows the exhaust manifold integrated into the cylinder head with only two outlets for the turbo to bolt directly to.
Unless my eyes are deceiving me, On my 2018 M240i there are six separate exhaust ports. The turbo is bolted to cyl. 3 & 4 ports but there are separate short tube headers with bellows that connect 1&2 and 5&6 to the turbo. Everything else looks the same.
WTF. Are there two different versions of the B58 cylinder head?
I would not expect that.
