Well buying a small supercharger from ebay is a start, then some pipe work stainless and silicon, oil feed and return hose and unions, an intercooler and wham bam thank you pam ! ! !

It obviously depends on mountings and inlet / outlet types, but once thats fabricated / figured out its a few man hours of your own labour to install... wish I had a V6 so I could look around and under the engine to give you guys a better idea...

do you know anything about it? who's got it? how was it done? what's the power output?

ooh, imagine if we could get our cars to be like the TAXI (Luc Besson). None of that crazy extending wheels and bodywork, but the sound that thing made... Makes my skin tingle when I just think about it.

please your trying to make us believe your car has 10k worth of mods?
anything else is just 'normal' maintenance that you get with any car its not really fair to add that in.
10k worth of mods on a 406 turbo would see well at a guess 400bhp ish maybe more depending on what route you took and if you went engine transplant or not .
you could even go for 2x twin turbo'd v6 engines for that if you done the work yourself. i know someone doing this to a spaceframed 205.

as for superchaging an eaton on ebay is likely to be an old mini eaton, now this would be no good what so ever on a 3l v6 it wont shift the air needed and wont create boost it will more than likely cause the engine to stall due to the engine holding back the airflow through the charger.you could change this by using a smallerpulley but then your going to decrease the life of the charger by a noticable amount.

however on cars upto about 2l the eaton is cracking due to being a self sufficiant unit it is as plug and play as the car world can get to superchargers, it has its own oil supply so no need to plumb in oil lines all it needs is air line in solid mounting and a drive belt , and wahaaaaaaaay you got boost!!!!!

persnally i am a turbo boy so would forget the sc and go for a V6 TT now im certain thats not been done inthe uk yet :) and you would be looking at 450bhp? so i would also suggest a mighty fine qauife diff to kep the power down, these things are awesome and i have seen 306's with 300+ bhp (t16 conversions) being able to get the power down with one.

btw niz i found out some interesting info for the guys screaming that the turbo engine has crap pistons............. have any of you guys eve blown any? id be suprised if you have it shares the same flattop pistons as the t16 and these are good for 300bhp, the turbo bottomn end is very very strong stock :P lol

Oh Dear oh Dear.... Malachy always knows how to come in ARSE end first :D LMFAO where does my car stands me at ?10k explicitly mean in mods... your forgetting that my car has had so much replaced in the last 5 years... a list off the top of my head would be including the purchase price of the car:

3 Turbo's
2 Intercoolers
Apex Springs
Stainless Exhaust
BOV
FCD
Clutch Assy Hydralic and Clutch kit
@ least 2k's worth of Audio
New front bumper

With the cost of the car and these bits plus more, I've spent about ?10k on it, I was talking about how much the car stands ME at not how many ??'s worth of MODS it has....

Oh and TBH with ?10k thrown @ it, you would be in the realms of 500hp+ :) easily..

There is one of a Merc Compressor, I wasnt suggesting a mini cooper S one... there are more than just the odd mini ones on there ! !

It has, low boost application running 300hp with 200hp Nitous on top... now thats crazy ! !

I personally would go for the Supercharger set up, reasons:

1) Less thermal impact on components, no build up of heat like the rotor housings of the two turbo's, meaning the extra heat will only come from the cylinders and not external hardware bolted to the exhaust manifold.

2) Colder Charge temps (denser oxygen content), due to above !

3) Easier and quicker to return to std set up unlike turbo conversion

4) Continuous smooth power delivery, unlike the surge of a spooled up turbo ! !

5) The grin factor, when you tell people its supercharged pushing 22 p.s.i of boost and 350+ hp :)

Serious..... ?????

Then why do ecosse and most other peugeot specialists recommend forged pistons as the first port of call when increasing boost levels ?? That statement is enough to question their experties...

Actually I could question their claims because @ 16p.s.i on stock pistons for a week I never had any problems.. but my mixture was too lean and so I backed the boost back off ! !

Well I heard that the crank in the turbo block was from a diesel unit and so are the con Rods and are good for massive boost pressures and compressive/tensile loads. Any ideas on that piece of info???

well considering there are no 86mm stroke dervs that answers itself, its the same crank as the s16 engine which also shares the same crank as the t16,
why would eccosse say that ? well ?600 in their back pocket would be why.
eccosse are known throughout the tuning circles to be rip off merchants.

so basically a 16v head (preferably s16/2.0Lmi16), new exhaust manifold (thereis 2x genuine t16 one for sale on 205gti drivers on brand new for ?500 and one with a few miles on for ?350), new inlet, a t28, 16v bottom pully,16v 2nd tensioner , and your looking at a t16 spec engine,well without the chargecooler although you can get them off a citroen derv from what i remember xm 2.2?
