Ebay Cast Manifold...
 

Has anyone ever used one of these and are they worth buying. Building on a budget and thought it would be better to but this than a more expensive tubular manifold. Are these prone to cracking or do they hold up pretty well. I will be running 8psi on a D16. Any input is appreciated, thanks in advance.

they will out last tubular manifold. ive never seen or heard of one cracking. only draw back on it is that it doesnt flow as well as tubular. i run one on my b16 only because its going to be daily driven and its compact so i can run p/s and a/c. i have a spare one but its b series. also see where the wastegate placement is. if its on one runner only watch out for boost creep but if its in the middle of all four runners like mine you dont have to worry about it so much...but 8psi is nothing so you should be good

perfect, mines going to be a daily driver as well and my turbo is an internal wastegate so i'll just end up blocking it off. thanks for the info
