It doesent matter if your car is multijet... 8V head is too restrictive.
And if you compare your engine to the one yan.ko has the difference is only in fuel pump, injectors, and compression ratio is a bit lower. The main problem is diameter of inlet valves in the head, which are too small.
Probably I wouldnt be far off if I tell you that with same boost pressure and same fuel injection 16V engine can do 10-15% more power at higher revs.
