^^ Get your cams remachined through redzman. I think it was like 400 or 500 dollars, but maybe PM him about it. If you don't want to do that though, I am going to be running a 1.8 with my turbo.

do you have a 1.6, 1.8, or 2.0l engine?
the 1.8 cam will be an improvement on the 2.0l engine. on the 1.8, obviously, you already have the better cam. If you have the 1.6, then I really don't know. I'm guessing the cam would have the same lift as the 1.8l cam, but it could have more, in which case you would lose hp by putting in the 1.8l cam.

nope, the 1.8l cam opens the valves for a longer period of time so it is better for both NA and Turbo.
I have also heard that some cams are better for turbo and some for NA but the 1.8l cam has been proven better for both.

280 duration
10.1 lift

274 duration
10.1 lift

268 duration
9.5 lift

with forced induction you do not want too much overlap between the valves. High lift yes, long duration now. If both the intake and exhaust valves are open at the same time (as in a long lift cam) boost can flow in the intake and right out the exhaust without doing a thing for compression.

What would it be a good combination between the intake and exhaust cams?

Only use the 1.8 intake cam. Don't replace both. I think 1.8 is still better for a turbo setup, but search by all means. Your question is probably answered somewhere.
