I installed a neighbor's swamp cooler this weekend, and I got $1500 to blow! My thoughts went directly to a turbo system for the 533i... I have read "the bible" but I still need to do the math for the correct size turbo, but from there I think Im good. I should need:

A TCD manifold
Wastegate to fit TCD manifold
Turbocharger
Bypass Valve
Associated plumbing
Rising Rate Fuel Pressure Regulator
Some form of A/F monitoring device

I only want to run maybe 8-10psi, so this should work right? I don't have access to a mandrel bender, but I do have access to a welder. Can I use silicone couplers to attach the straight intake pipes? 10psi shouldn't blow them off if I do it right, I hope... What am I missing here... Oh! Exhaust system. Should I go with the TCD unit or build my own?

EDIT - It's either this or stash the money away for my 6er that I am trying to sell, or my future Porsche 928S... Any suggestions are welcome.

For piping, there's no reason you can't just buy mandrel bent angles and cut them to make the angle you need. A couple 90s and 180s should do it.

Good point, why didn't I think of that??

What size / AR is the turbo you used, just for reference... I know you have a 3.4, but at 10psi I can be "in the right ball park" and probably get decent results.

The silicone couplers are good for 35psi+. There used on very high pressure systems.

Any 35lb/min turbo will be fine for 10psi. But no room for upgrades.

A TCD exhaust is about as good as you can do.
