You will max the supercharger put way before you need these
no the real restricion is the inlet manifold you can always gear the SC down to stop it going above max rpm. Where as the gas velocity will choke the inlet manifold at just over 7krpm no matter what you do else where.
Exige S is capable of 330bhp with the eaton MP62, and thats only 1.8 but then does rev to a redline of 8.5k rpm. There should be more to had from the supercharger - could be worth looking into a better inlet manifold, and then maybe look at destroking to 2.0 and running higher rpm.

the z22se oil pump is best regarded as the 'early spec' pump, the saab B207 and z22yh both use the same revised 'later spec' oil pump.
Any difference in parts/material between the Z22SE and f.i. the Saab B207 or Z22YH pump gears??
the GM Racing oil pump gears are billet, the standard are quite poor quality in comparison
Would the z22yh/b207 part be a straight swap for the z22se?

if you try and buy a new oil pump for the z22se (from the dealers) they will supply the 'later spec' z22yh oil pump
