Supercharging z3m

[M400DPC]

I've posted on this topic previously, but now have some funds to one side to get cracking would appreciate any feedback/info generally on the topic of forced induction on s50 & s54 engines.

I own a 2000 s50 z3m. Looking to up the power to between 450-500bhp. Supercharging seems to be the way to go in order to retain the linear torque delivery. A couple of questions if I may:

1.would it be cheaper for me to modify the internals on th s50 or just swap the s50 in for an s54?
2. Can anyone recommend a tuning company who have successfully carried out this type of conversion on an m?

As always I appreciate your expertise gents.

The S54 engine and supercharger set up are a bit different from the Z3M one to say the least.

If you are going to supercharge a Z3M Coupe... The one in my profile might be for sale soon. If you are interested pm me for details. And yes, it is the original G-Power car which established them as the premium forced induction tuner for ///M cars.
