So for next summer i was thinking about throwing in some comp cams(turbo grind) w/ cam gears. I was just wondering if this is gunna be street friendly on a DD? And will i need tuning after they are installed? the car will be turboed eventually i talked to smg and they said it would be ok but i wanted your guys opinion on this good or bad or any other mods, like bigger injectors i believe would also help.

More air needs more fuel, so: Yes, you'll need bigger injectors and a higher flow pump at the least.

Go beyond the "bolt-on".
