BMW's are not that easy to work on. The new engine in e46 max out at 333hp/na. OR 343 in CSL form but thats it. I don't think there can be a head work done which can give a boost upto 400hp. Second, you have 2.5L littler engine since you have 325i. EVEN if you were to super charge or turbo charge your car, you will need FORGED PISTONS to begin with. Then, different compression, bigger injectors, intercooler, camshaft, hoses, water pump, new ECU software and many many more things. AFTER every thing is done, then there will be the issue of reliability. Don't forget you will also void any kind of factory warranty.
Also, when you replace the fly wheel, there will always be a rattle at low rpms and clunking sound at high rpms. It is not hurting anything but the noise will be there because BMW uses dual mass fly wheel and single one will leave too much space. The only way around the noise is to use m5 fly wheel assembly.
ALAS, if you love your car our and are worried about the reliabilty, I wouldn't recommend any kind of forced induction. But if more power is your forte, go with DINAN. They will give you upto 48 months of guaranty depending on your engine history.
