As for the dump valve forget about that if you are just starting your build you will be a long way away from needing it!
Im trying to get all the parts together before fitting it. And not that far away from needing it. Once I have all the parts, it should be fitted in a weekend.
Ok ok so you already have the engine built then and are just looking at the ancillaries then?
Yeah, turbo'ing the current engine, and will be fitting a 28cc chambered head to give me a compressions ratio of 8.5:1 and fitting a tamer cam at the same time.
I've got to get a fuel presure regulator and exhaust and bulkhead box.
Just unsure about the dump valve I've got at the moment, no name on it, and doesn't feel great quality.
