    Red Bull (5541)

    https://timesert.com.au/ No personal experience but advantage vs helicoil is supposedly the solid structure of the timesert vs the spiral of the helicoil. In the situation you mention I wouldn't be keen on a coil inside a coil... The bmw reputation I mentioned is tied to turbocharging the m54...

    That interior colour/grain combo is beautiful

    C111 Epic Soundtrack M117 TT

    I wonder what else they did to the m117 besides the twin snails to get 500 horse at 6500... certainly seems like quite a redline bump from standard...

    Red Bull (5541)

    I've no experience of this exact job but in a situation where your (m100, right?) heads and manifold are actually quite valuable I'd be strongly favouring: A) avoiding any chance of a shanked bolt corroding and damaging the hole in the manifold, especially cracking it or pitting the sealing...

    Mercedes V8 Inlet Manifolds

    Theyll cool the valves better if the droplet size is smaller. Sure you may dump more fuel per cycle with a poorly atomised spray to get the same effective AFR but it's about heat transfer capacity (which favours surface area to volume ratio) more than it is about heat capacity of the liquid fuel...

    Mercedes V8 Inlet Manifolds

    If they're going to ITBs, why would they stick with the original injector location in the head when surely plugging those holes with a match to the port profile and siting the injectors immediately downstream of the throttle bodies would improve mixing, not to mention allow a more compact...

    I wish Australia wasn't so fringe when it comes to Alpina. There seem to be a decent number of them in the UK so it's not a rhd thing, and the popularity of bmw here seems pretty high. Same for amg anything and the rs Audis of late so money's not the problem... And They Fixed The Awful Grille!!!!

    60 years of the 600

    €450. Not thousand. Max. As a modified car (and that heavily) it has no chance of ever getting german historic registration, and thus would be subject to ordinary registration and taxation requirements, and since its not Euro (what are we up to now?) 7? emissions compliant that means no Green...

    Car of the week

    Haha! Deja vu! I bought a 550i from Grays SA in 2021, only to discover a parking ticket under the driver's seat with its previous Vic rego. Put that into google and hohoho; sold by Grays Vic in 2019 with 120000km more on the clock than I bought it with, which massively explained why the cluster...

    Yeah I'd do it the same way as you. That engine and transmission both I'd want to put back in the car only once ;)

    Ahh ok. I would like to rebuild the 3 speed even if I do end up doing the engine swap (I'd eventually rebuild the m116 too, since it's original to the car as far as I can tell. I'd just keep them stored in case of future preservation-of-automotive-history desires). I'm conscious of the march of...

    BTW: who did your 560 trans rebuild, and what should I expect to pay?

    ooouuuuu. Someone else with my rebuild mindset! Thanks for posting all of this by the way, it's really good to have input from someone with more than my (nearly non-existent) IRL experience with Benzes. So much US-centric or downright confusing information on some things available online, very...

    Yeah I was always pretty sure the internet tables I found were incomplete/misleading. My understanding is that there is one beefed up version of the 722.3 that the 560s used, and all others are lesser to differing but substantial degrees. I should check the german W126 site etc again, i havent...

    Gearbox stuff W3B050 390Nm 722.3 hard to find different versions but none seems rated above 290Nm 722.62x-64x are the 580Nm ones, all others are 330 (or 380, or 400 for a few odd ones in the .68x or .69x region). Bells need adapters onto alloy m117 711.6 and 716.6 seem virtually the same but...

    At least they'd have saved me the hassle of organising it myself 😉 But srsly im beyond pleasantly surprised that it didn't get towed or even "dumped vehicle stickered" in 13 months on the street. Guess my neighbours like me...
