Renntech claims 394 on the SLK 32 for the performance package 1 which consists of pulleys and ecu reprogram... costs 3k, but this will not be the number on the crossfire... you will also need to replace the camshafts (1.8k?!?) and that would probably still not do it... and as for nitrous that's an option many people choose not to take... and you cannot blame them for it.
The 3.8 liter engine conversion will probably get you to about 425-430, but it will run you at least 12k.
With about 5k 400 FWHP is probably possible without nitrous or an addition of any kind of forced induction.
I actually had plans on doing this, but my car crash of my sister's car has cut me short.
