I have DSR street cams in my car right now from a Dinan SC Vortech kit. The specs for the cams are.

256/250 0.430/0.405 214/200 @ 0.050"

Im trying to find some stock S52 cams if these wont work well with turbo.

Could i leave these in and run a turbo setup? Will there be too much overlap? These dont seem too much more aggressive compared to stock S52 cam specs.

S52 cam specs - Intake/Exhaust
Duration 252 / 244
Lift 10.2 / 10.2

I dont know what is the lift on the DSR, but they are regrinds, so there cant be more lift, right?

What do you guys think?

lift is what you want. You can also degree the cams in such a way to eliminate/reduce the overlap. You would need a dial indicator with a decently long plunger and a degree wheel.
