Would it be a good choice to transfer a cam from an engine with a positive dis. blower
(ion) to an engine with a cent. charger (my soon to be s/c eco) I did some research and I know that there is not a cam develped yet for the boosted ecos, unfortunatley. I've been reading alot of the "performance forum" and they have some horror stories. I think if a bunch of us get togethor on this we can get something done, without having our boosted/soon to be boosted j's be guinea pigs at our own expense. There are enough smart people on here (and our fair share of not so smart flamerific people) that we can get something done without waisting our money.
What websites have you used to research your cams for your boosted 2.4l? or 2.2l?
It's just now cutting it's teeth.
mostly the reason why nobody has done it is that there would be a very marginal gain at best by changing them
the stock cams are very boost friendly if you want to spend 400 bucks on something put it into working on the cylinder head or internals

But why are N/A egnines spending $600 for 5 or 6 hp and a crappy power band? I would thing the gain for a boost cam would be amazing? but i guess who would know.
stick a fork in me ...im done

cams are generally for high hp N/A applications but have been used for boost
Have any of you Eco guys ever looked in the cams from the turbo Eco used in the Saab 93 or cams from the Reline to see if they have different specs???

lol skilz I was JUST discussing that, I plan on using my dealer hookup to get me a set of redline cams to see if they help

Not sure how different they are if at all but the turbo Eco cams may be better for you. My guess is that they would provide better low end power if at all different.

see I thought they wouldnt be different but 90% of the people I ask say they have to be different

boosted,
You have to use your connections and try those cams! and then let us know how they work out! Don't make me resort to second grader tactics!!!!
In all seriousness you should try them! it would be a great mile stone and you coule become famous to the org! like the guy who found the secret cam for the 2.4l!
try it!

Great question and I have no idea myself

N/A cams would work great if you advance the Exhaust cam 4-7 degrees (depending on the profile). The Ecotec requires a profile that is turbo-friendly already, so even N/A performance cams have the qualities you need.
The only difference between N/A and boost cams is the lobe seperation. You want less overlap with a boosted cam because you don't need to scavenge to get more air in, the boost does it. Therefore, more overlap on N/A = Good, more overlap on Turbo = Bad.
If you advance your exhaust cam, you're cutting down the overlap, and raising the EGTs a little. This will help with spool up and reduce lag.
Even if you simply used your stock cams and advanced the exhaust 4 degrees, you'd see better results.
And I'm not just shooting my mouth off, I'm a cam grinder who specializes in n/a to turbo conversions, and I have a couple hundred hours of dyno-tuning experience.
Good luck!
