Let us know if u wouldn’t mind me coming to see u and sit in for a ride one weekend. I love cars and this is so nice. Drop me a pm if you don’t mind. I’d just love to have a look at her and in return ur welcome to take mine for a drive and advise me on any alignment or mods that would help. Hope to hear from you. All the best mate and hope the weather gets out nice wherever you are so u can get out and enjoy it.

On a side topic. If my N52 goes bang (please don't) and I needed a new one to keep the old girl going. (3L SI Sport). If you were to put a very rough ballpark to get that replaced with another motor (second hand) for supply and fit. What would you say the very very rough cost would be for that?
No worries if not possible, as I guess the task is hard, but I'm just wondering and I want to keep my zed going for as long as possible.
On that same note, what would be an economical way of putting a more powerful engine in (ideally BMW) e.g. M3 engine / V10 / other v6 bmw engines?
Just playing with ideas here, but of all guys you seem like the one to ask hahaha

From another thread that Stevie w commented on. To give you an idea of the man hours and work needed for a v10 swap or any engine swap and a car built to this quality. (This covers everything I own and they were happy to put a value of 60k on the V10)
Any engine swap will cost a lot of money to complete Truth. It’s not just the physically getting the engine in. engine mounts cross member modifications, piping rerouted. Bellhousing adapters made to mate engine and gearbox. Prop shaft shortened lengthened. Final drive gears adjusted the list goes on.
But the biggest difficulty is then getting it running and wiring and getting the ecu working. To give you an idea I am building a custom turbo build on the same engine that came in my car. The stock ECU won’t do what i want it to. So i was looking at £1500 for a standalone ECU then probably another £1500 bill to install check and map that ECU. I think i have got really lucky and found a company willing to use my car a test car so that they can offer a plug and play ecu for the z4. And that has halved the cost for me. But custom car builds cost mega money.
Keep the stock engine. If it goes bang just replace it like for like. If you want more power buy one of the many BMW supercharger kits. You won’t get more BHP for £££ than that. £5k may seem like a lot for S/C kit but doing anything else will cost more.
My build is getting very close to the £5 mark and i have built almost everything myself. I am a machinist/ welder/ who has 20 year’s experience making and fabricating custom one off things for the scientific industry.
I am not trying to dissolution you. But just know this type of thing is far from cheap. And even further from easy.

Your so right Monkey when it comes to custom work and bespoke items that require manufacturing. I’m sure on my original build thread guy’s we’re asking if I could do a conversion for 10K . I started a list of items I bought to start the build and 10K was swallowed instantly!
I estimated at my hourly rate I would be 25K on labour
. My complete build costs were 23K including the car. So as you see it ain’t cheap and to replicate wouldn’t be much different, actually would probably be lot more as S85 engines are getting scarce and managed good trade deals on items. I know having covered all the ground another build would progress quicker in reality.

I'm going ess come March when it isn't freezing cold. I did toy with the idea of ditching the car and buying an Alpina but this will be more... fun 300bhp sounds pretty appealing for 5k. Will give a 4 day turn around for fitting and panic. It does seem like a lot of money but 50% power increase for 5k is nothing. Well look at this way. For 10k all in with the car. You'll be hard pressed to find a motor that's as fun and rapid for that.
I'm pretty new to all these graphs and stuff - http://esstuning.com/ess-n52-vt1-supercharger-system-gen-2/
It says a 80 to 100hp boost on N52 3L.
Looking at these graphs - http://cdn3.bigcommerce.com/s-00nxb64g/products/630/images/1407/Z4_2__02756.1443412815.1280.1280.jpg?c=2
It seems like a very even power delivery, hitting around max 325hp... Not bad for the money considering that's around the same output as the Z4M. Also means the weight of the car is generally lighter than the z4M variant.
Considering I'm **** with DYI, how long would it take a mechanic / someone good enough to fit this? Is it literally plug and play, or do you need to tweak it / change ECU set up?
Sorry I have no idea with these things.

Best bet is to contact someone who offers turbo mods etc. At least they'll have some knowledge of what's required. Mstyle for instance will fit it for £800. Now given if they are on £100 hour.. well do the math. I intend to set aside a whole spring weekend to allow room for error, problems, nuts that are a c**t to get off, taking a break etc. But I also plan to change all the drive belts, drain all fluids and what not. May as well right.
Just go for it. Granted transplants are a different thing as you need a crane and just plain not viable to attempt if it's a one off. But the SC kit seems pretty straight forward. Most parts of the z4 are. The only things that seem like a bitch to do is anything involving the exhaust or driveshaft.
I learned most of my stuff out of pure defiance to my dad. He owned a repair shop that purely worked on supercars and classics, he put right refused to get me involved or into it. So I started by fucking up my 1.4 astra lsi and then rover 220 turbo and then got some lessons and off I went. Soon after I blew the head off the engine (turbo too big) I got (slightly) better. There are very few things you can realistically break or make non reversible on a car. Like accidently turning a cam wheel. Which I'm sure some of us have all done. But if you don't attempt it you'll never know.
