Hi.
I am building cosworth yb engine weeks ago i buyed holset hx35 turbo with ar 63 turbine, also i buyed bd14 inlet cam. My doub is if bd14 and std exhaust cam will work fine?
i am thinking change bd14 inlet to bd 16, and use std to exhaust or use thist bd14 to exhaust.
Any advice obout porting and cams should be wellcome.

Head is in porting process it will porting to 25mm inlet and 25mm exhaust, engine is 205 block with std,std crank, grA hasket , valve cuts std pistons, stand alone ecu...

My holset turbo would be equivalent to garrett gt3076

Thanks
