    How do you add bhp to a e46 2000 323ci, without adding a superchager?

    I believe you can fit the inlet manifold off of a 325.I think this was the method used to deristrict the 323.As they are both 2.5 cc engines.

    Use the forum search engine for posts regarding this,iv seen a few over the years.

    you can not add the inlet manifold, that was for the e36.
    these are the m52tub25 lumps, not the same as the e36 m52 lumps!, the only way to add bhp on a cheaper side is to remap it, but that will only get you around 5-8bhp!, but the big picture here is the change in response and how the power is delivered!, out side this there isn't really anything you can do to it!, except the m52tub28 engine swap

    I have heard mention of a manifold swap, possibly using one from the 330i, but I'm not sure if it is entirely problem free.
    There should be a non restrictive exhaust upgrade too, possibly E46 325 or 330

    A decent exhaust, big bore throttle body and a dave f induction kit maybe some cams with a remap should give good power gains. I've had an exhaust and remap and its made a massive difference.

    As mentioned above, good exhaust with a good induction kit, the more air can get entering the better the combustion, also want a good exhaust so the air can leave as fast as Poss which will remove more restriction, a good set of plugs will boost bhp a little not much though, you can also get the maf meter chipped to trick the ecu, no remap required.

    Hi James,

    Remap will work well.Around a gain of +18 bhp & +20 nm torque .

    You can check the website for more detailed info buddy if required or get in touch.

    if you get an exhaust don't expect much!, most bmw standard exhausts are that well engineered that they already get nearly the most they can from the engine!, also induction kits and plugs may net you 5bhp, but if you add all the mods together(and i mean the best mods as you will be wasting your money other wise ) you will be paying a hell of a lot!, and with all that you may ask the question of if you sell up and put the money you would spend on mods then you could get a 330. but if the 323 is the car you want and will be keen to up the bhp, please get the best!, scorpion s and k&ns are not the best!, eismann, dave f etc. but just look at there prices.
    on another note, 2.8 engine £350, fitted at an indi for £500. alot cheaper than the mods, and prolly more power, with more to gain.

    Just a question for those who may know. I've currently got a 323i. Is there a vast difference between the 323 and 330 and is an M3 totally mental compared to a 323i? Thinking of either getting a 330 or M3 next year.

    330 is quite noticably different, more so when cruiseing and needing that bit of overtaking grunt. also when you start getting weight in the cars, the 323s start to feel heavy, if you know what i mean?, where as the 330s superior torque keeps the car feeling light.
    m3, different league. every thing underneith to the sheer power sound!, the car is wider, different camber, better brakes and suspension, more raw power delivery,, but isn't as smooth as the 330.
    i would love 1.
