    hey man...personaly ad go for the supercharger(if a had the dough!)immediate and constant power...no turbo lag if you get a turbo(obviously)and am led too believe that mist will take you from 231bhp-320bhp without uprating cams,clutch and brakes(your gonna need too stop at sum point!)ess twinscrew supercharger are sposedly the dogs bollocks!also mossman by m style...and if youv just robbed a bank try thorney motorsport...they will give you the best advice as they ha a few race cars(e46 m3 csls and astra vxrs)good luck!

    just to let you know check out ca automotive in leicester or simpson motorsport in gloucester they both do ess superchargers.
    labour isn't cheap but the charger makes a huge difference to performance.

    The kit for yours is sold at caautomotive and costs £4912.85 + £350 labour

    very price in looking into supercharging any engine...

    Had a few figures thrown at me for supercharging the v6 vectra i had and that was something daft like 6K. and only running 6psi boost.. which is the tops the v6 vectra could cope with!

    There's a book called "Supercharged" by Corky Bell, published in the UK by Brooklands books (or it used to be when I was learning about it), which teaches you all about the different types of superchargers, how to choose the correct one for your application, how to fit them, how to calculate all of the power increase vs power loss to drive it etc., belt thicknesses, how to calculate and achieve correct fueling, stuff about intercoolers and basically everything you need to know (aimed at petrol engines, but the theory would mostly apply for diesels too).

    You can buy superchargers slightly used off eBay (esp. from the states) for reasonably small money ( a couple of hundred quid up), Eatons are popular (routes type chargers - like fitted on the Mini & some Mercs etc.) but that is just the charger - you would then need to make up the ducting, mounting brackets, drive pulleys and sort out the fuelling etc., but if you take the time to read up on it its not actually that hard, just time consuming. The big bucks that you guy's above are quoting are all for "bolt on" kits, where someone has done all of the hard work for you. It doesn't have to cost that if you are prepared to make a bit of a project out of it.

    I learn't about them about ten years ago and did some work with them on the Rover V8 engines, and didn't spend mega money on anything - it depends on how much you are prepared to do yourself.

    I only looked at this thread today because I'm about to replace my 2.8 Nikasil with a good low milage steel linered 2.8, and I made the mistake of flicking through an old Summit Racing catalogue this morning... and then got thinking...and now I'm making tea, and in a minute I'm going to look under the bonnet of the 328 with a tape measure. The Missus is not going to be happy...

    personally i wouldn't turbo, have seen many melt pistons and cause damage to rods and heads!, the turbos are also prone to bearing failure!,my mate had one that failed, got recond with a new 360 bearing, then that failed after 2 months!
    The turbo cars i have been invloved with hav had uprated rods, pistons, thicker headgaskets, different cams ecu upgrades and exhaust manifolds and the turbo itself!, yes with all the parts upgraded you can get massive bhp!
    but with a sc its more or less bolt on. and the power starts when you turn the key!, a second stage set up for a supercharger with a fmic and you will have a lot of power and it will be more reliable than a £ per buck equivalent turbo.
    there is a reason why in america nearly all there tuning is from superchargers, not turbos, they leave that to the jap boys!, and us 2litre 4 pot europeans.
