Yes the I4 & I5 both have 10:1 turbo really need somewhere around 8:1 or lower on a NON Turbo Factory Stock engine Plus the pistons probably want last long since there not designed for the extra temps the turbo will be generating it may work ok if only running 2-3 pounds boost which probably all it can do since like GregDAP said everybody that has tried one said it was junk !
There NO Way Those Atlas engines can handle any Major Turbo Boost without doing some Major upgrades Pistons, Rods , Crank , Cylinder head work .
