Need a little help figuring out what to do. I have a 4LEK holset turbo that is compaired to an HX50, so im told. What kind of psi am i looking at and would it work with my setup i will do. Ill go with DD2's and head bolts. Do i need a gasket and O-Ring? Will i be able to wastegate or get the housing right to be able to run that turbo or should i just go with something else? I have the transmission and VB done also, should i get the input shaft. Im looking for around 430-450HP. Thanks for the Help.
