I'm going to get a turbo cam and i would like to know what cam and who from, also what valve springs and retainers should i get?

depends on what u want.

jmm recommend dev 3hl for good performance and every day driving. they also make a few other specially designed for a turbo 4L, they also sell the 1 used in brendens xr6 witch is also the same cam pryoay is using in his xr6.

or ring crow or surecam and tell them what u got and they will workout whats best for you.
