    OPC Engine upgrade?

    I am sure I heard you can get an engine upgrade for the 2.0 Astra Mk4, parts being OPC stuff. Anyone know a price for the parts or have a link for me. And whats the final bhp once done? Thanks

    This sounds like the OPC engine upgrade Courtenay offers. Think the total was 165bhp. Take a look at the Courtenay website to see if it is what you wanted mate
