It would be great to learn that it's more suitable than I stated. John (wants a 16B) Dave Wilenius wrote: This seems to go against what I thought was conventional wisdom where the Renesis is lighter and doesn't have the same level of exhaust bark, making it a good choice. If you want between 180-200 hp is this really that difficult? I was also under the impression that the placement of the exhaust ports on the side housings improved fuel efficiency. If you design goal was fuel economy with 180hp would you still opt for a turbo REW?
