Just got this back from them:
"Hi luke,
A basic kit fitted is £1,100
If you want any optional extra's then obviously the price goes up.
Fully fitted full spec kits fitted are £2,300
To build and fit the kits it takes around 5-7 days depending on parts availability and whether the machine shop I use has time to modify the supercharger and make the adaptor plates.
I order in the top spec injectors from the states so sometimes they can be here within a few days and then sometimes they can take a week or two.
If you'd like a basic kit made then once the deposit is paid I can get one done with in a few days and contact you once it's ready to send out or collect.
All my kits are guaranteed for 90 days after purchase.
We use eaton m65 chargers these are used units and not brand new, but are in excellent working order and checked prior to modifications are made.
Any further questions please don't hesitate to ask.
Thank you for your enquiry

It may just be booked in pretty soon!

Thats a really good price. I wonder how helpful he will be if i want to do some of the work myself????

Anyone attempted to get insurance quotes for a supercharged Z4.
It's one of the things that has put me off supercharging somewhat, as I was either getting "thanks, but no thanks", or "would you like a mortgage for that, sir" type responses.
However, I guess my risk profile is unique, so it may be simpler for someone who uses the car less, doesn't have business use, European cover, track day cover, etc. or parked on the road/drive in Liverpool

What would you do yourself though? The standard kit just on its own is £900 + £15 postage so he's only charging £200 to fit it! As great as it is to tinker and fit yourself... £200 fitting is probably too good to contemplate doing it yourself! With the added assurance you have somewhere to take it back to to iron out any wrinkles.
Or do you mean help making or machining some of the components yourself? Even so at this price is it worth it?

Luke are you looking at going for the standard kit £1100 fitted.?
Will it still need a remap after it's fitted.?
Does the engine need work doing to it to make it stronger.?
If it's just £1100 and your ready to roll then that sounds fantastic. Oh god I want this.
Go on Luke DO IT...DO IT...DO IT....DO IT....DO IT...DO IT...DO IT....DO IT....DO IT...DO IT...DO IT....DO IT....DO IT...DO IT...DO IT....DO IT....DO IT...DO IT...DO IT....DO IT....!!!!!!

I have been speaking with these guys, they are based in Leighton Buzzard and happy to build a kit for the n52 too, they are also happy to do a group buy discount (10 kits or more) sounds like a very tempting prospect, im definitely in, but they would need a local n52 car to use for reference to create the correct brackets etc...
Anyone in the area who can help with this?

The engine should be ok for 75-100bhp the m54 copes with 6psi quite well apparently. Much more and then you need to start uprating things internally.
Myself and SK93 where looking at making a kit up like this. But it seems there is no need now

Yeah....IF they get an extra 100hp.
That's a compressor of a merc slk200 kompressor (and clk), and is best sized for a 2L engine or so. That won't cope with a 3 liter and certainly not an extra 100hp. Most other tuners use a compressor that has about twice the displacement.
The m65 (it's actually an eaton m45) does about 100m³-300m³/hr with a 1.2-1.5 compression ratio at 65% efficiency. A 3 liter engine needs 585m³/hr at 6500rpm (no loss of air friction etc included!, but calculated at 100% fill). At that time the m65 operates below 45% efficiency, and is probably ratteling apart (you'd have to spin it at about 3 times the speed it spins in the merc
). Any idea how hot this thing is going to get? (and with no intercooler..)
So this compressor is far too small imho. The efficiency sweet spot is nice at 1.4 ratio (so it is a useable design), but this is very clearly a compressor for a 2 liter engine tops with a fairly low revline.
Mercedes used these on a 1,8L engine with 163hp @5500rpm and a 2.3L with 190hp. These are nice engines and pretty easy to bump to about 220hp (for the 2.3L) (smaller pulley), but that's about it. And that is what they do good (OEM quality), and this compressor is ideally tuned for that engine (needs 300m³/hr for 5500rpm at 100% fill)
But no way that it can bump 100HP(!) on a 3.0L 231HP (@5900rpm) engine (so 330hp in total), let alone an S54.
This is a unit that is popular to boost an mx5 or a corrado g60. A nice unit for small engines to boost moderate performance.
Not having a finished picture isn't much reassuring either. And both the z4 m54 ECU (ms45) as the z4m ecu (mss70) are not easy to tune right. Lots of experienced tuners (VF, ESS, AA) have trouble tuning these right without quirks (AA doesn't even do these ecu's on boost)
This unit may fit the M54 2.2L, but that has stock already 170hp Ithink. So It might bump that to 220hp or so, which is not bad (certainly for this price), but they still have to get the tuning right, and make a decent setup (good bracket, leak free, adapted CCV etc etc). Other injectors might not even be needed.

So it is to good to be true
Very impressive write up GuidoK...
What do you do for a living mate.?
Once upon a time i looked at an eaton m90 for my car.
Cut a long story short... The n52 cant be boosted without a lot of costs... So its not even worth trying.
Based on what GuidoK is saying i would actually agree... As i was told i would need an eaton m90 at a minimum.

The m90 is indeed very well matched for a 3.0L and displaces about twice the air of that little m45.
That one is reasonably comparable to the Lysholm 1600ax that ESS uses for the 3.0i m54 (the lysholm does a little bit more air if required and has at the higher boost regions (above 6psi) a little higher efficiency (4% or so)

M112 is a little bit bigger than the m90. too big for the m54 engine.
If I look at the maps quickly, the m90 maybe is the best choice for the 3.0i on high revs&high boost, but the m62 is also a nice match.
It's hard to predict because it also depends on the efficiency of the filling of the cilinder.
Maybe the m62 will perform better in the mid range and the m90 will give a higher top end with proper cooling.
I think if you're not planning on an intercooler the m62 might be better. It is much more efficient so it will produce less heat. (if I interpret the eaton compressormaps correctly and if they are correct).
Bigger isn't always better. With certain rpm and certain boost you need a certain airflow. So you want that amount of air with the highest efficiency.
But with unexperienced tuners be ware about their tuning. I think the ecu tuning is the tricky part, the hardware is the easy part.
Especially on higher boost (so with a lot more power than the ecu expects) you can get really dodgy fault codes.
My engine used to go into emergency mode (no gas pedal anymore, just 1300rpm) when I was at altitude. But only at altitude above 1500m.
With a really dodgy code that the ecu calculated far more power than the expected output. No s**t with an 8psi supercharger....
And that wasn't on full throttle, but sometimes at 50%, sometimes at 35%, sometimes at 70%. Probably a hidden torque mapping that was not adapted or so (that is a mapping not present in most ecu's). With further upgrades that problem disappeared.
So especially when you go maybe 33% (80hp+) over stock you can get strange things (I had about 55% over stock back then (ess TS2))
Also with wrong tuning (too much pre ignition timing, low afr) you can really damage the engine. Great power, but bad lifespan.
