Well When I had a machine shop put together my head and port it they put cams that are for NA..

Or as It seems AM I wrong?

INT CAM: Lift .440
Cam Lobe Lift .260
Valve Lift 258
Valve timing @ 0.050 41 bbd 3- ATD
Duration @ .050: 216

Exh Cam Lift .436
Cam lobe lift .258
Valve lift 262
Valve timing @ 0.050 2- btd 38 ATD
Duration @ .050: 218

Does anyone know best specs for big turbo 2.2l? Or have a Recommendation for an Aggressive Turbo Grinds I have an EFR 8374, Head is 94lb springs +1mm Valves And Im thinking these are hindering me rather than helping me. No Dyno to confirm anything yet Obvs

 

If you got adjustable gears you could probably make them work okay

 

Those sound like the stage 2 supercharged cams that I have. Still way better than stock 2.2 cams
