    Hi i may be coming into a little money soon and want to increse the power of my car.

    short of buying a new car, (becuse i do like mine), would it be better just to buy a new engine instead of supercharging or turbo charging.

    Vac motorsprots sell a fully turbochared 6 cylinder engine for £5500, at current exchange rate and simpson racing in the uk have M3 engines from as little as £3000 they say. When some supercharger kits ive seen can be £4000 to get anything near that power out of an 323, would i be better just replacing the engine.

    or another option a second hand salvaged m3 engine, then i would have to be carefull of the condidtion of it, but proces are looking around the region of £2500

    Or after costs of new ecu, gearbox wiring ect would the price rise dramatically.

    Thanks

    Ideally if you could get a donor vehicle ie ones thats had a rear end smash then you could get everything you need off of it and put it in your car I would take a naturally aspirated engine over a forced induction one personally-then if you like you could supercharge that

    Thanks, dunno if this needs a new thread but, Has anyone had any experiance in fitting an e46 m3 engine into a e46 2000 323i. After Obtaining all the needed parts will there be any fabrication involved, to fit the engine and move any other parts in the engine bay. Becasue the engine is bigger im guesing some things such as the rsevouirs may need to be moved.

    For example can the engine mounts from the donor m3 work or will new ones need fabricated. would i want to change the stering, diff ect.

    Sorry for the long and drawn out questions, but im really interested in doing this.

    You would at least need this
    Complete engine
    ECU
    EWS Module
    Transponder Key
    Transponder Ring

    However if you did have all of the things you've listed will make for a much better conversion job
