Adamski - The process of adding a turbo would probably result in replacement of the manifold anyway so unfortunately your point is invalid.
The biggest problem with turbo-ing the 2.0 is the valvetronic system it uses, its very difficult to setup a replacement ecu to run correctly on this type of engine and pretty much impossible to piggy back the original. Any type of forced induction (turbo or supercharger) will inevitably cost you a fortune as you will be paying the R&D costs.
There was a Chinese company that were going to sell a supercharger kit for the m46b20 but as far as I've heard, they kept blowing head gaskets. Its a shame nobody has put the time in to tune this engine because it could make some decent power for its size and weight.
As others have suggested, going the 3.0i route is probably the cheapest solution. There are other engine options depending on what you are after... I hear good things about the GM V8's. Personally I would like to see you spend your money wisely and sink an LS9 into that Z of yours

I wonder if a BMW 135 engine would work, I'm not really clued up on these things but imagine the power from a 35 lump from either a 135 or 335, they can generate some awesome figures
If your going that length anyway why limit to an older 3.0 engine from a Z4

I think we're both making the same (valid!) point
The standard manifold couldn't take boost, so would need to be upgraded one way or another.I think in the previous half dozen threads on Jonny's engine situation, the majority of advice was to get a 3.0i lump installed (maybe something bigger), or sell the 2.0i and get an M, swapping all compatible mods over.
Separately, some well intended advice is not to forget to upgrade brakes etc, as the 2.0i brakes will not be designed to take 200bhp ++
There's a company that sell bmw power units and drivetrain for a fee. Will try and dig out but tbh it will cost more than the cost of your car then all the labour and know how.
So unless you have money to burn and by that I mean 20k plus your wasting your time.
Just buy a v8 Aston or Maserati gt or anything else.
While the above will cost more than 20k, if you have that money to burn then you can afford a better car than the one you own.
I know it's a personal thing mate but everyone needs a voice of reason 8)
Just surprised it's me

S54. Arguably the best I6 BMW engine ever.
The z4 came from the factory with the m54 so why not just opt for that? It would keep things relatively simple as it was an OEM engine for the model and probably much more affordable than an s54, especially given as you're paying to have the swap done.
Though if you are interested in an s54 conversion, Ben Koflatch has managed to fit one to his e36 touring relatively recently so he'll have plenty of knowledge on S54 swaps.

johnny, buy a 3.0 with a M54 engine, bolt over all your upgrade parts, and then sell the 2.0 . that's option 1
option two is take it to a shop for a V8. i know mannhart racing in Germany can, ( they done the Hornisse (wasp) v10 Z4 ). but they will not be cheap i guess. otherwise search a UK shop witch is know to BMW and engine swaps.
i wouldn't swap in a 3.0 or an z4M S54 as then all the logic is gone, and you'd be beter of buying a 3.0 or Z4M.

You'll need an engine, and probably best to go with an M3 diff for the extra power. Sounds like you have the bigger brakes sorted. Suspension wise, I'd consider a stiffer setup to avoid excessive "squat" under power.
http://www.esstuning.com/products/M54B30-Twin-Screw-Stage-2-(TS2).html - this will give you 345 hp, which is just a little more than an ///M, so an LSD will be handy getting the power down
There's a stage one that does 320 hp - but why would you want that :wink:

I'm no mechanic, but surely it's the final output torque of you project, that is going to determine the answers to these questions. A highly tuned 20I Turbo, is possibly more likely to lunch your drive train, on over boost, if it has a bad moment. than any NA engine in the E85 range.

if you go N54, you'll have the same problem as the V8/V10 swap, it's not that hard for a shop to make it fit etc, but the electronics will be the hard nut to crack.
i'll stick with my first option, witch i mentioned before, as you can allways turbocharge/supercharge the M54 3.0.
