got mine from rpm motorsport in ware. cost a tenner. works a treat. dont bother getting one that goes to -bar, you want one that starts at zero and goes to 2 bar really. esspecially if you intend on putting hte boost up.

Kenni, the Zafira GSi isn't turbo'd is it? Cos dump valves are only for turbos.

no, most turbo cars come with them as standard, it just dumps the boost back into the car so you cant here it.

Didnt think a dump valve evn fitted on a turbo diesel corsa as the dump valves all rely on backpressure through the turbo and you dont get that on a diesel
