It has been proven very difficult to release any more power from the NA. ITBs are the best way but very expensive. Most supercharge and get and extra 100bhp. Have you considered S/Cing?

I have been thinking of installing a supercharger but found that there would be concern every year during the car's inspection.I think it would be easier to get through with more hp without sc

you would need Dutch software to use a 65mm TB, but apparently it's well worth the effort.
To get 200bhp from your z22se NA;
increase the compression ratio to 11:1, either skim 1mm from the head or fit z22yh pistons and rods
fit supertech or Dbilas valve springs
fit CompCams stage 2 cams or Piper regrind stage 1
fit a 2.4 inlet manifold or Dbilas intake manifold
fit a decent 4-1 exhaust manifold and a 2.5" system (Tullet are very good)
Have the balancer delete done and increase the rev limit to 7800rpm
Also worth replacing a few items whilst the engine is apart, new rings, chains and a water pump. Use genuine parts as the cheap pattern parts are not intended for high power builds or track use.

Got my NA up to 199bhp @ the fly (dyno is a pessimistic one too).
Ported myself, piper cams, 2.4 inlet manifold, Z22YH pistons, Z22YH rods, TTV racing billet flywheel, balanced crank, balancer shaft delete, 2.5" Tullet system inc cat & manifold, Diblas valve springs, LSJ injectors, 2.4 throttle body (GM part no. 12580195), own design 70mm inlet pipe with modified standard air box (and standard filter), Dutch ECU. :-)

Great minds ..... :-)

Do your government yearly tests include opening the engine bay lid and even looking at the engine? In the UK they don't and most MOT test guys would not even know that your car is supercharged (if the whine is minimal).

No, they only see the engine on the outside and check the exhaust gas values. Then they look over the ordinary on the car However, if you come across compressors, they may require the car to be checked and then you have to restore all parts of the car to original parts.

sounds very good. think I will build something similar. Does the dutch ecu works well?
Does the original bottom of the engine handle the increased effect? or will I need to upgrade the pistons?

Dutch ECU software works very well
Standard pistons and rods should be fine for 200bhp
You could fit some Eagle steel rods, but possibly a bit of an overkill.
Opening up the exhaust ports is also a good idea, just use a standard OEM gasket and open them up to that
