there are many parts required to modify a Saab B207 to use in a z22se engined car
oil cooler blanking plate

exhaust cam blanking plug, with modification to use the z22se cam cover

The ITB manifold will be port matched for better flow, plus the PCV has been modified to work with the z22se inlet manifold. The B207 hole has been plugged and a new hole drilled to join the two chambers together.

I need to make some new injector blanking plugs as the core plugs are not a great method to use. I know of one z22se engine which failed because a core plug fell into the inlet and got sucked inside the engine, whoever installed that kit didn't install the core plug correctly.
