Probably closer to 5lbs, BMW uses a really dense foam to quiet down the direct injection.
Exhaust probably weighs a fuckton too, the one on the F56 Mini is like 40 lbs and can be replaced with a straight pipe because the turbo+cats do a lot of muffling. I'd expect at least -25 lbs there, and there were actual power gains because BMW decided to choke the engine with a catback so they could sell an overpriced JCW exhaust that's actually worth a good ~5hp in stock trim and more when you turn up the boost. Swap the 19's for 18's for a good 20 lbs of unsprung weight, just like the 86 I bet there's an easy 100lbs to shave off without much sacrifice.
But I realized a few years ago I've got a pretty low threshold for trading weight for NVH so I wouldn't mess around with stripping a shiny lightly used Supra.
