All sounds dodgy to me mate. A hybrid turbo for 265?
WHAT hybrid is it? You could fit a ko3S comp wheel to a ko3 and it's technically a ko3 hybrid!
Or you could fit a ko4 turbine wheel to a ko3S and call that a ko3S hybrid, although in reality you've created a ko4-001.
Find out exactly what internals he's talking about fitting.
My choice would be a ko3 hotside with k04-023 internals from Littco as they've been proven to make over 280bhp on typical st2 mods.
