  1. The evolution of BMW is a predictable thing. Mercedes went through something similar in the mid-90s when the accountants took over. Great cars up until then, with a reputation all-but destroyed by cost-cutting measures, 'economic' engineering and a massive drop in actual quality. The hewn from rock feeling old Mercedes had was lost, starting with the rust-prone W210. Some of that has been regained, but it'll be a long time before Mercedes are actually known for it again. Newer BMWs, and newer cars generally, just don't grab my attention. Aside from the fact I'll struggle to work on them, there's monumental amounts of technology in them just waiting to go wrong (in my opinion). That tech isn't even used to it's limits - look at cars like the Koenigseggs now being produced... Even they are combining known working solutions, but to far greater effect. BMW are about making money, of course. Sadly it seems (to me) that has become a predominant reason for manufacturing cars, rather than something they work toward as a result of the cars they have made. Makes economic sense, but ensures the amount of soul involved will be tiny, if it exists at all.

    M10 top end

    T'other way about. The M12 and M13 engines were based on the M10. There were a lot of differences, and the older they get the more powerful they were. In reality, I doubt anyone really knows exactly what power they made, but it was a lot. It's safe to say the F1 qualifying engines were making well over 1200hp at their height, although reports of 1500 may be enthusiastic. The race engines were typically 6-900hp depending on when and the circuit. I don't yet know if it will happen. There are a couple of ideas I have that need verifying for actual viability rather than satisfying any 'be realistic' type issues. If it happens, it will be ludicrous. Maybe not Koenigsegg One:1 ludicrous, but you get the idea.

    M10 top end

    I don't think anyone has ever considered mentioning common sense when talking about me! You're right. It is pointless. There are other ways of achieving the same thing, several of them being from Honda, but that's not the point. I know you know what I mean! Cost is an issue. I reckon the top end - cam, rockers, valves, springs, etc would cost around $3500. Forged titanium H-beam conrods: another $3500. I can get a 2.7 stroker crank, but that's almost a mortgage away! All these parts are rated solid and reliable beyond 10000rpm. Let's have a chat about your M10 some time.

    M10 top end

    It's Friday evening, dark outside, too many flying bitey things in the garage when the lights are on, and for a variety of reasons I have time on my hands and no alcohol to help pass it. So, I've started doing a teensy tiny little bit of planning for what I would like to do with an E30 coupe shell. I made the decision a while ago to stick with a 4-pot engine. Lighter than many 6-pots, and more room to work. And fewer cylinders means fewer expensive parts required. And that's as far as it got. In the interests of moving things along, I've since decided to go with an M10. It's original. It's a nice, simple, strong and reliable engine. (Yeah, I know, I'm missing a trick with the opportunity of some of the later engines but I'll live with it.) Admittedly, this decision was influenced by exchanging some emails with a friend in Denmark, who has a friend in Sweden, who has done some silly things with M10s. (And that's without getting into the whole M12 and other variants discussion.) Most recently, he's been developing some top end parts. Roller rockers maintaining better geometry than stock, but weighing more than 5g less. Each. That's over 40g saved from just the twiddly bits in the top. This guy has been testing the rockers, too. He's set up a kit to test cams, rockers valves and springs. Pre-warm oil (of course) and see how long it takes for them to break. It's no fun doing these things at normal engine speeds especially when that's not where they're likely to be used, so how about winding the whole thing up to 10000rpm, walking away and and leaving it for several hours? Subsequent measurements show no measurable wear. An accidental spin to over 15000rpm didn't break anything, but that wasn't sustained. So, this seems like a good idea. Just need a crank, block rods and similar that can do that, too. And a gearbox. And...

    E36 bargain

    Imported from...? Anywhere hot and humid will mean the headlining will be sagging soon, if not already.
  6. Coulda bought my 16s for that sorta money, and they've got near-new Michelins on them! I s'pose when you've got a fancy motor, it has to look all proper-like, even if it's only standing in the driveway... Saw some Style 97s earlier today. I could be persuaded to have those on the 320d in place of the 73s...
  7. Unfortunately for my wallet, I'm far too nice! Even the freebie E36 bar I got some time ago I gave away! (Albeit in exchange for the recipient having a look at another car for me.)
  8. There's a guy in Christchurch who I know had one removed from a Touring. I'd considered it, but shipping put me off. You're hardly next door to him, but you are a lot closer than I am! His name is Dan Cain, he runs Veloce Wrecking, and his number is 022 4444 297. [email protected] No idea if he still has it available, but perhaps worth a try?
  9. The steering wheel on our 320d needs attention - we've pretty much worn it out. However, I suspet a CSL anything is likely to be more than we'll pay. But price... Find out what a new component would cost, and divde by two. Review the figure you get a decide if you as a seller like it, then ask yourself if you would pay it. If you wouldn't pay it, there's a good chance others might feel the same.
  10. A good-looking gold PFL E65 being driven by an at least equally good-looking young blonde lady, heading south on SH1 as far as the TK turning, where I started to wonder if I was being followed! turns out the owner lives just up the road from us. Wouldn't normally give them a second look (however nice they are) but this one had the drivers window a little down. Struck me as a trifle unusual - luxury car with aircon being driven on a hot day with a window open?! I'll keep an eye out.

    Clarkson Sacked

    Apparently there have been further 'production issues' with the new TG, pushing release back by (yet another) couple of weeks. And, further 'differences' with the new head host of the show. It seems Chris Evans, one-time famous ginger person and husband to one-time Dr Who girl, Billie Piper, argued against hiring Matt Le Blanc because MLB "is a has-been." Executive producer Lisa Clark has quit after Evans insisted on last minutes changes in content and direction. Lisa Clark was also (coincidentally?) the person who suggested MLB should join the show. Clark and Evans have been at loggerheads for some time. A script editor quit after clashing with Evans, and Evans himself threatened to walk claiming he was being micro-managed. Suspicions are Evans thought he could 'be' Top Gear, replacing the entire previous team and Andy Wilman who was pretty autonomous in his role as producer.
  12. The Porsche 928 uses lightweight aluminum nuts. Very, very light indeed.
  13. Arild had a thing for building non-standard 4x4s. From 1985 thru 1987 (pre the E30) he ran a very quick turbocharged 4x4 Lotus Sunbeam. I think this also had Xtrac running gear, so maybe it was swapped from the Sunbeam to the E30? There are suggestions the M10 in the E30 may have been one of the ex-Megatron units, but I think it was more of a home-grown engine built on an S14. Certainly the Sunbeam was largely a DIY job. The further it fades into history, the more powerful it gets! I recall mention of 'over' 700hp, but later stories tell of 850+ and how the tyres were bolted to the rims to stop them coming off (which is possible - several rallycross guys did this). From a review of the '88 Rallycross championship race at Brands Hatch: "... standing down by the wall at the bottom of the pits alongside the Cooper straight during that cold misty British GP meet, when Martinsen came off Hoppy's Drop and accelerated along Cooper Straight... Sideways through every gearchange, before having to scandie flick it the other way to negotiate the left through the gap to get onto the start line. My mate and I just looked at each other slack jawed and then burst out laughing....."
  14. Just worked it out - that 6R4 is Will Gollop's car. Maybe the world's first (and only?) twin-turbo Metro 6R4. It made something north of 650bhp. Still no match for the power of an M10 in an E30, though!

    Quick rant thread.

    Drivers who move into the right hand lane of a dual-carriageway for no reason whatsoever!
  16. Double? The beauty of a crash box (at least, where a S2 is concerned) is you can change gear without using the clutch at all. I drove my '62 S2a from Oxford to Norwich (in the UK - 160 miles or so) with no clutch. Started out sweating at how hard it would be, got to Norwich with no problems and didn't bother sorting it for 3 weeks. Setting off is the only difficult bit. This is the one I know of. Very seriously tempted, but I'm almost as big a wuss - I want a roof for when it rains.
  17. Actually, no. I was going to say that's not a S2a, but (of course) it is. I suspect only LR Series aficionados will understand!
  18. I know where there is a SWB 2a with a SBC and 4-speed manual...?
  19. It really doesn't take much water to make and oil look sad. You can find emulsion under an oil filler cap on a cold morning on some cars, where condensation has built up enough to mix with a little oil. Presumably the underside of the oil filler cap is just showing oil, particularly immediately after a drive?

    Mtech1 side skirts

    Hmm. A swap with Ray looks a good bet. I'm keen, but my purse doesn't bulge that far. Doesn't bulge at all, actually.
  21. Head gasket is a possible culprit. Any sign of coolant being passed through the exhaust? Exhaust fumes will be more like what you'd expect to see on a cold morning, and can smell sweet. (Sniff your tailpipe! )
  22. There is a fair bit, but the area that counts doesn't vary so much from rim to rim (within the bounds of having the same pcd).
  23. The 6R4 is the only Metro you can get away with saying that about! 4wd, mid-engine 3-litre V6 making up to 410hp, normally aspirated. Lots got turbos for rallycross.
  24. Aye. Forged rims are metallurgically a little different to cast ones. I took 6mm off the inside face of some AMG 18x8 et31 rims to make them and et37. The et31s rubbed on the front of my W124 but 6mm is all that's needed for free running under all conditions.
