converting to fuel injection (740)

    Hi all,

    Does anyone have information/experience with fitting a cylinder head off a 2
    litre B200 series engine onto a B230K, a B230 head gasket would keep the
    piston crown/rings away from the slightly smaller diameter combustion
    chamber, but;
    Are the valves smaller?
    Do the valves have the same 'travel' in the head/ ie, are they the same
    length, with the same camshaft lift?
    Would the B200 engine be suitable for fitting a turbo (I have one spare!),
    without messing around with sodium filled valves?
    Assuming I fit a turbo how safe is it to NOT use a thicker head gasket, or 2
    stacked gaskets (this was recommended to also be for using unleaded fuel to
    reduce the burn temperature, but I barely trust one gasket, never mind 2
    stacked!)
    Are all the oil/water passages and bolt, studs, stretch bolt holes in the
    same places as the B230.

    Simply put - can just simply install the 2 litre head on my 2.3 litre block?

    I ask this because I would like to install the other head due to it being
    available and having fuel injection ports, I would then fit all the fuel
    injection bits, and possibly this turbo I've got lying around, is this
    feasible?

    You might be thinking - wouldn't it be simpler to just change the engine
    block? Probably it would, if I hadn't already changed all the ancillaries on
    the front of the block to what's normally on a turbo model, plus which I
    know my block, it's sound (for now :)).

    But would it stay sound if I did what I'm proposing?

    I've read that the 2litre FI engine has slightly more HP than my 2.3litre
    carb engine, but, I installed an auto tranny last year, lost some 'get up
    and go' power as a result, and, would like to use the even extra power I
    think I could get from my 2.3 lump, to make my car shift a lot better.

    Any and all advise welcome, sorry for asking so much!!!
    Thanks, Ken Phillips

  3. I *think* this won't work. There's a bunch of wiring and computer
    differences between a carburetted and a FI engine. It's more than just
    swapping the head.

    I once put a carburetter on a '73 140 which had been FI and it worked
    well for many years. But I don't believe it's possible to go the other
    way.

    It's possible, in fact it shouldn't be *too* difficult, but I'd look into
    something aftermarket like Megasquirt in this case. It's not a trivial
    project but it's doable.
