Well, I'm sure I'm going to get a lot of hate for this... I'm with you.
As much as I love my M6 6sp vert, these cars are fundamentally flawed and I think an engine swap (non BMW) is a brilliant idea. Imagine not dreading thr chime, an engine you're not worried about every time you start it, something that you're not "preventatively" replacing CRITICAL engine components to avoid the grenade scenario, something that at least somewhat RESEMBLES reliability.
Me? I'm plannning to do rod bearings this spring and to drive my car for one summer and if that goes well, maybe a second summer. If, the expected happens and something catastrophic happens to this engine made of glass, I'll NEVER replace it with another s85... Yes it's amazing, yes it sounds glorious, but let's be honest, it's a horribly flawed engine. In 2007 (my MY) it was untouchable in terms or power and performance but reliability, give me a break - the idea of taking this thing on a long road trip is a joke and shame on BMW for what this has turned into. It's a lab experiment that should never have seen production. The S85 is beta at best!!! Vanos pump, vanos solenoids, rod bearings, throttle actuators, injectors, SMG.... What doesn't fail on these that doesn't cost thousands to replace?
Enter the LS SWAP!!! (Yeah I heard the groan...)
IMHO, swapping it with something you know you can count on, is the only thing that makes sense if you love the look, the handling and want SOME reliability. Even an unreliable engine swap would be better than the perpetual expectation of failure of the S85... Alternatively if you have more money than you know what to do with or you're just a masochist who loves to watch your guilty pleasure leave on a flatbed, while you "Burn My Wallet" (BMW life) by all means keep spending money to keep the pin in your S85 grenade, but only just... You'll suffer eventually.
Sloppy mechanics gets 900HP on a with a junkyard LS with a new cam and a turbo, surely a marginal increase in component quality could yeild happiness for E6# owners too.
I'm not naive and of course this is a huge job and subbing this job out to someone would be very expensive but if you're willing to learn and integratethings that were never meant to work together anything is possible, as long as you ignore the naysayers you can make anything happen. FTW! And FBMW! (Last one I'll ever own)
