    Your looking at about 4-5k if you do all the work yourself and can make most things as well.
    With great challenges comes great engineering.

    asa or ess chargers seem to be the choice of most bmw tuners, expect around 4-5 new, can get for less, and sometimes people sell them on ebay for a couple of grand, even 1 went on here a while back for 1k!
    They run standard 6-8 psi totally reliable, but can be made to run a lot higher than that! but you may start to pay the price if your foots made of lead.
    50-60bhp for entry level, and up from that at extra £££. but the best thing is its bolt on power! easy peesy.

    That can´t be compared to a turbo conversion as a turbo conversion to make 6-8psi is just a waste.

    4-5k will net a gain of 150hp at least. And compared to the SC kits is only marginally more expensive.

    you wont initially get 150hp from a turbo mate, like has been said max 10psi 50bhp

    exactly, nearly all production standard turbo models make 50bhp over there sisterengines, the tuning and chipping and uping boost to dagerous levels gets you more but not reliability unless you start getting pistons rods and thicker headgaskets etc, thats where the big money is!, turbos are cheapish, the special manifold and internals arn't!, super chargers are bolt on, no internals neaded for most applications, and as said 6-8psi will be no worries for the bmw engines that seem to respond perfectly to the sc, and you can get 100bhp extra on thecharger too, with a little bit of cash!,
    chargers work off the engine so the power is there from straight away, turbos give a little more but you have to spool them up!, same idea in theory(forced induction) but different power delivery chariteristics

    Who has said this?
    And where is that claimed to be true in an engineering sense.

    I didn´t say that a decompression plate wouldn´t be used. The engine can handle 150hp more no problem with lowered compression.

    4-5k of DIY money WILL get you 150hp more.
