Mein Auto: 2007 E60 530XI
Super/turbocharged N52

Hey all. Right off the bat - I know I should just buy a 535, and the N52 isn't the best engine for forced induction due to the magnesium aluminum composition. But I have a 530XI, and I put a lot of work in to it. It's not just a 5 series anymore, it's MY 5 series.

What's involved in rigging together some sort of supercharger or turbocharger for this engine? I know ESS sells a drop-in kit, but $5000 is a little steep and I'm big on DIY.

If I bought just a turbocharger, or just a supercharger, what's involved in getting it working? Is it as simple as hooking up the pipes and/or belt and calling it a day? (To oversimplify)
What about coding? Necessary? Would it be possible to steal a 535's guts and slap them on?

I'm pretty clueless when it comes to forced induction. I recently learned a friend of a friend just finished a turbo mod on his subaru. To quote him,
mine isn't a drop in kit. It's a td05h off a jdm sti and the original ej25d has been swapped with an ej20k bottom end and twin turbo heads that I converted to run a single turbo.
This makes me feel like it's possible, and within my means. Any help is appreciated.

You will spend so much more and have so many more problems building a 1 off kit. And in the end it will devalue your car when you go to sell it.

$5k is nothing for forced induction.
