Dunno - not that much is known about what's REALLY inside them, I can theorise that they have either standard internals, or super tricked up conrods and pistons...
Problem is, like I said, nobody
really knows what's inside.
Just look at the blanked off DV outlet (couldn't look in the charge pipe to see if it has baffles, could you?), bolt down coilpacks, lockwired everything and scrutineering tags, extra MAP sensor on the inlet, inlet manifold (is that flowed?), different FPR.
It might have different injectors, there appears to be an extra take-off on the LHS of the charge pipe, I wonder what the turbo is...
Where did you get it?
