Looking for some build guidance

Hey there! I've got an m440i xdrive convertible (gen 2, b58).

**Current mods**

* AA downpipe
* Dinan intake
* MHD ECA
* S58 injectors
* xHp trans flash

**Goals**

* 10.5 quarter mile
* Keep stock trans
* Keep stock cat-back exhaust

I'm pretty sure that any of the hybrids will get me where I want to be. With E40 in the tank, the car ran back-to-back 11.48's at the track on the OTS stage 2 map. The car had a full tank of gas; DA wasn't amazing. I could reliably chase after an 11.3X pass, but I'd rather skip that and go after my 10.5 goal. There are 2 local used turbos available: a 6769 and an Omega 65, both in the $2X00 range. While the price looks good on the used turbos, does that leave me with a severe lack of post-purchase support from the manufacturer if I need it? I'm 95% sure I'll need the DS25 HPFP as well to reach this goal with whatever I pick, so that's in the budget. The injectors were picked up because FCP Euro had them on the cheap.

What do you all think? I think that any of the DAW or Pure offerings that are complete units will handle it, but there has to be some pros/cons between them. It's mainly a weekend top-down cruiser, but I think a solid mid-10-second car on a 'mostly' stock exhaust will be a fun surprise when I want to get on it and fly under the radar from unwanted attention.
