My understanding is that I can push the turbo harder, it'll just be less efficient. I don't know have the flow maps for this turbo, so I don't quite know the efficiency range at which they're quoting for 350ps.
I also thought that allowing the turbo to breathe a bit better may up the efficiency range a bit, too.
I'm hoping with the increased duration and increased intake area with the port and polish, my motor will simply have more time to take in the air, gaining a bit more hp. I guess I won't actually know what happens until I finish building, tuning and hit the dyno.
I will run the 264 duration cams. I heard that any higher than this, there is (in addition to really lousy idles), the chance that your motor won't even fire up. Yury over at heavythrottle advised me against the 270 Tomei cams. He said that his car wouldn't start with them in. I don't know how that can be so but hey, it's Yury. If he told me the world's coming to an end I'd probably believe him
