Are Saab 9 3 cars comfortable and reliable used cars?

Does the turbocharged version of the GM 3L-L81 V6 engine used in the Saab 9-5 utilize the same intake and exhaust valves as the same engine without a turbocharger used in other GM cars?

• Answer:

  i do believe that the valve radii are the same at the point at which they meet the guides. the length from flat face to camshaft however could be drastically different because the block is the only part that is reliably exactly the same. the cam timing and lift would be different because of the different gas dynamics that exist in a forced induction engine. the head and its components could be different but i honestly cannot say. = = = = = AFAIK, the heads on the V6 engines in Saabs are specific to Saab and not used in any other GM model.
