seems like i'll be going with the 530s from the research ive done and from what ive heard about them to this point, stock turbos are leaking oil.. more blue smoke from the right exhaust then from the left. Nearly no power from boost(with a ton of blue smoke afterwards that blinds every person behind me). Since my engine needs to be rebuilt i've decided ill probably uninsure it for the fall/winter and take is slowly. Looks like JWT530s, 3" SZ dps, and z1/greddy intercoolers will most likely be my choices. This will be my first engine pull..lets hope its my last for a long time lol
