    if you are looking at kits there usualy priced between 5-8k and about 1500k fitting with set up so its not cheap.
    i ive got an a new asa charger and 80% complete kit that id like to fit but no funds at the mo.pm for details if interested the kit did retail at 7k.

    depends on what sort of gains you are after, that site rjb posted is quite interesting and it gives you an overview of the price and gains. That being said it would be a lot cheaper to just drop a 3 litre in there and get 40hp more than the 325

    If it is actually an SMG then it should take anything that's thrown at it, it's the Getrag 6 speed box. Perhaps a HD clutch'd be an idea. If it's some sort of auto box trying to masquerade as a proper SMG then who knows???

    Cheers

    Hi everyone and thank you so much for your views and help on this matter to be quite honest i expected the gain to be a lot higher and so being i do not think that 4000 quid justifies only a 40 bhp gain so i will not be doing it plus i dont really want mess with engine itself ill just leave it stock as it is with regards to the gearbox it is a stock SMG not an auto and its only five gears its a 2002 325i i know its not very common to see them on a 325 normally see them on the M3 i think its cause they were a 1500 quid extra when the car was bought new , personally i love it and have had no trouble with it others hate it it takes a while to get used to it and personally the only advantage is not having a clutch pedal the paddle shifts on the steering wheel well only used them when i have one hand otherwise occupied other ways never.

    Many thanks Peter

    check out a-l tunings website mate..a lysom twinscrew supercharger will gv you way more than 40 bhp and will be at full boost way before any other supercharger out ther..they also re map your gearbox too suit.. so no problems ther either..i was in touch with them regularly and was quoted £6k supplied and fitted..even gv you a courtesy car..they are very well quoted in the bmw scene..unfortunately i still havent got the dough yet..if you ask they sometimes have second hand ones too
