I have the 403's and the valve springs retainers, valves etc. i was wondering if the 403's would benefit me if i turbo the motor?

The 403's are deigned for a mild/moderate NA setup but aren't setup agressively or specifically for a NA build. They are kinda like good general purpose cams and I have heard of people having success using them in their turbo builds if you tune it properly.

If I'm not mistaken, the greatest difference between the 403' and the 411T cams is that the 403's have a larger lift both intake and exhaust. The duration is the same for the exhaust, but the 403 has slightly longer duration (shouldn't cause overlap) on the intake.

As long as you're not shooting for a an all-out monster turbo build, I think you'll be fine using them.
