What do I need for a stage 2 map

[Poodle]

I don't understand the fascination with hybrid turbos, it adds so much cost to a build for relatively little benefit. Just fit a decent-sized unit, gt20 or td04 or k04 or even a gt17, and it'll be great. Slightly later spool, but that'll save the clutch, higher exhaust flow than a hybrid and can be done for £100 all in. Especially if you're talking about making it revvier, the problematic restriction on the stock turbos isn't on the inlet side so much.
