Coolant leak between turbo and manifold, HELP!

Coolant leak between turbo and manifold, HELP!
I have a 1.6L greddy turbo miata, and everytime I top off my coolant, or put on my high pressure radiator cap, I notice 3 things:
1. Motor shakes
2. RPMS VERY choppy when throttle opened
3. Coolant seems to be leaking onto the headers from the turbo, around the gasket.
What is the problem here? What needs to be repaired/replaced?

i'd check:
the lower radiator hose, the one that sits directly beneath the turbo.
the hardline that mounts directly beneath the manifold, it only sits in with an 0-ring, that could easily fail.
the coolant hoses on the firewall.
the headgasket

Any chance the turbo's bearing cartridge could be cracked causing a leak into the turbine side then running into the manifold? The missfire could indicate a blown head gasket where coolant is entering the combustion chamber and exiting thru the exhaust then seeping thru a leak at the turbine inlet flange. Is there any (heavy) condensation or milky oil on the inside of the oil cap?

if you have a leak between the manifold and block, it's from the coolant hardline spraying up onto it from underneath!
it's not your turbo.
