I'm assuming that stock internals will take 12psi and pump fuel. How long it lasts is another matter. For anything over 12psi I would go with custom internals, not cheap what so ever. If you want a reliable high horsepower engine you will have to spend big $$$. I've been looking into it a bit. Take Beeto's car for example. Try to emulate this car. Personally for a high horsepower application I wouldn't skimp on anything unless I had a second engine ready to drop into the car. It may sound overkill, but here's a list I've put together so far (they don't all have prices);

- turbo
- fuel injectors
- custom pistions -http://www.racetep.com/jeimport.html#bmw – US$1490 for 6
- custom valves - www.ferrea.com
- valve springs http://vacmotorsports.com/cgi-bin/vi...ine+Components – US$340 for 6
- Reinforced Rocker Arms http://vacmotorsports.com/cgi-bin/vi...ine+Components – US$600 for 6
- Custom connecting rods - http://www.pauter.com/bmwrods.htm US$1620
- new or reground cam
- intercooler
- wastegate if not on the turbo
- new headgasket
- custom piping
- new exhaust and exhaust manifold
- gauges
- cylinder head studs
- engine management

Then there's labour on top of that and probably a heap of things I haven't mentioned. 400rwhp is a ton of power.
