    NE1 with info on turbo'ing an M10 motor....

    with weber side drafts on it?

    I have a 1972 2002 that I'm finishing up and I would like to add boost to it. IT has a built, bored & stroked, balanced & blueprinted, 9.5:1 forged JE pistons, S14 crank, big 6 chain, mild head work and a 292 Schrick cam. It has dual 40DCOE Webers on it which I think would handle some boost up to a certain point through them. I can create the piping for it but I'm just wondering if any one here has heard, seen, done this sort of transformation?

    Should I just look for an S14 motor and turbo that thing instead?


    Any thoughts, comments are apreciated.

    TIA

    Didn't the M10 run massive boost back then?

    I thought the M10 block was the one they were able to get insane amounts of horsepower from back in the day. IIRC, the turbocharged M10 was able to achieve 800+ HP with corresponding levels of boost.

    Can anyone here provide more info or links in this regard?

    Cheers...

    Rev High,

    Talk to me, brother. Email/PM/Boards/Etc.

    I will do my very best to share the bits of information I've collected over the last couple years. My '73 is awaiting its 3rd resurrection and 1st turbo. I am completing final logistics on a particular blow through carb concept. The majority of Bimmer and motorsport folks will give a 'no way' or big thumbs down to such, but a few of the gurus (including Korman not that long ago) have good sentiment to keep the carbies on!...

    Sincerely; Respectfully,

    Yes, and that was with nearly a stock block.

    From what I've read...

    The builders needed to scrounge well-used 2002 blocks (M10) from junkyards, since the iron was run-in and held the least internal stresses.

    The engine (in qualification trim) pegged their dyno at 1300 HP. It eventually put out over 1400 - from a 1.5 liter 4-cyl. Whew! So, the block can take just about anything you throw at it, for sure.

    I'm still impressed with motors that produce 100+HP/liter (well, NA), BMW developers made one with 10x that. What an effort!

    But, I don't know any publications which outline the "how-to". Wonder if researching via the factory museum would help?

    Cool. I'm looking for hardware(exh) to do this so

    fabrication can be kept to a minimum. This engine needs boost.

    I have carbs though. A bit different and if I go

    to fuel injection I would move over to the S14 platform.

    Re: What to do about exhaust manifold?

    My tii has been turboed since the early eighties and the exhuast manifold is getting beat (made by the Turbo Manifold Company which has been defunct for ages). What do M10 people use for an exhaust manifold these days? I have a beautiful manifold designed for an Aerodyne turbo, but it doesn't fit anything else. What about the factory 2002 turbo manifold?
