I'm now starting to build my second turboWbx engine and want to do some mod's to it.one of them is maybe exhaust valve.
The WBX head's have stock 34mm exhaust and 40mm intake valves.
Since this is a turbo engine ,some people say that equal valves is a way to go.
Is it poosible to use the intakevalve as a exhaustvalve ..so the setup will be 40mm intake AND exhaust.
A friend told me that the stock exhaust valve was another steel quality than the intake...so maybe the intake valve was not suited for exhaust use.??
Or is there a source for aftermarket valves for the WBX heads?
