    I just recently acquired a 1987 BMW e28 528i. It has an MSport trim to give it the looks.

    If there are any classic Beemer guys out there, Here is where you tell me what works and what doesn't in a old e28.

    I don't plan on giving it a full restoration, although I have dreamed of pulling it apart and refurbishing every part of it with autosol and a toothbrush.

    The car is currently undergoing cosmetics at a body shop. Welding and paneling to remove some rust had been completed, and is now currently getting a new paint job as we speak. The original colour it came (greenish blue).

    I have some plans for her, maybe Dana; pronounced day-na as a project name.

    Nothing too crazy and mostly performance upgrades. I'm a big fan of properly tuned naturally aspired rear wheel drive cornering machines.

    I've been reading a lot about the e28 and to surmise from the mostly European tuning guides, I have come up with a plan below.

    I haven't stuck gold with the forums when it comes to the e28 in Malaysia, but that's probably because the old diggers that use them are buried in their work rather than in their phones.

    Without more witticisms, here's the hot bits as follows:

    #BRAKES

    Upgrade brake pads
    Brake hoses to braided lines
    Lines flush
    Master cylinder tweak ABS

    #SUSPENSION

    4 set Street/sport coilovers.
    (need recommendation on brands)
    So far Titan, bilstein, h&r
    these would need to be adjustable and suitable for letting the ride height 20mm to 30mm

    #GEARBOX
    Inspired and rebuild

    #DIFFERENTIAL
    Inspect and rebuild

    #ENGINE
    Gasket kit
    Pistons to high compression ratio
    Stroker kit
    Oversized radiator
    Head rebuild (maybe a later M30 head)
    Custom header manifold
    Lighten flywheel
    Balance pistons
    Balance crankshaft and flywheel
    Flush injectors or upgrade them
    ECU remap or upgrade.
    Hi flow catalytic coverter or removed
    Cat back exhaust


    The philosophy behind this car is to create a semi sleeper 5er.

    What I wish to achieve with its performance is as follows gents:

    More torque
    More horsepower
    Quicker and higher revs
    Better pickup speed
    Dynamite braking
    Balanced engine
    Stanced ride
    Lowered ride
    Stiffer cornering
    Appropriate body roll

    I still require much information to achieve the above. I would very much appreciate the knowledge of ya bros!

    Cheers!

    I admire your passion for the E28 to be honest. I have the E34 and been a great 15 years till today.

    Engine wise, the factory M20 / M30 engines are nice and can be fun to work on. But judging from your post, I am skeptical if the 12V engine can satisfy you for long. I just find that when churning more power from these engines, the sensation can be a bit dry. Especially if you sample the newer BM engines.

    I would advise going for newer engines. Even the M50 / M54 is a good start.

    As for suspension, the only 2 that you can consider is Titan like you suggested and RCS. Both of which I've tried among other custom coilovers. Titan built the most bullet proof shocks hands down though they aren't the best in outright handling or circuit performance. RCS are pure engineer based outfits and are very focused in handling though product life can be a pain in the ass. both are rebuild-able of course.

    good luck

    Amazing Tom thanks for the info. I reckon you are spot on when you said an engine swap would be necessary.
    And thank for your enthusiasm, I fell in love with the e28 the first time I laid eyes on her.

    A few questions though, Would I be able to reuse the gearbox and/or what other mods do I need to achieve this? Mounting, etcetera.

    I'm still new to the circuit and would appreciate a starting point on tuning shops that are reliable and stock the products I require. For example where do I go about finding a M54 motor?

    Also I'm keen to see some photos of your e34.

    Sure you can reuse the gearbox if you absolutely need to. The newer engines won't mate with the old box so a conversion sandwich plate has to be fabricated to the bell housing. But most gearboxes that comes with the new engine should fit the E28, though i'm not sure if the V8 ones would.

    Engine conversions would likely affect the mountings, but chances are, they are as simple as the height of the mounts. No promises though

    I trust BM World most and if you haven't already got a shop for BMs, you can try them
