What turbo/cp3 and injectors would work well for a street only truck,looking to make 650 maybe 700hp at most? Any advice would be appreciated

I'm building the engine now, so if injectors and cp3 are needed now is the time!
I would like to stay with a single charger if possible.

I traded the pulling rig for a lifted lmm, then sold it shorty after for a pretty profit! I recently bought an 02 ccsb for nearly nothing that had bent pushrods,so I'm building the engine in this rig to enjoy until I decide I want something different

I found an Aurora 5k kit cheap from a local, is its street manners fair or should I be looking for smaller?

I have never ran a K31 but have friends who have and they have always complained of high EGT's and a higher DP number... A billet S472 will spool lightening fast and flows IIRC the same as my S475. Converter selection will also dictate spooling behavior. I have a Mike L. Precision Converter that has a stall speed of 2700 RPM my turbo spools really fast for a 3.0 charger. If I was you I would go no smaller than an S472. Sure you could make 650 with an S366 but I would much rather have really cool EGT's and more air than fuel. PLUS! the expandability of a T4 Borg Warner charger is great...

What TC do you have? The ML or the high stall PI. I I thought the ML had a lower stall than that. And I don't think the a5k is a very balanced charger, anyone have the specs on them off hand

ya but it is better to have them balenced which requires you to send in your complete injectors.
