According to TT today, the 2.0 head is better in stock form as well as the base for beginning to port.
While you could adjust lift on the exhaust cam to match the 2.0, what happens when you install that same cam in the 2.0 head with it's already larger intake ports? The stock cams have more lift on the exhaust side. Obviously the exhaust side is the more important of the two. When talking with Dick@Shine Racing, he tells me that when he wants to port a 16v head, he hardly touches the intake ports at all, just cleans up the bowls a little. He spends the majority of his time on the exhaust ports... On the 50mm intake mani's, I think it's been proven to give about 5 more hp up top then stock. Obviously with further mods (cams, etc) your gains may be larger. Only you can decide if that's worthwhile or not... -josh --- Ralph Smith <[email protected]> wrote: > "When a dead horse just isn't enough......" > > The 2.0 16v head IS the better head vs the 1.8 16v > head!----Um, well okay.
