need help picking turbo parts hey guys i just picked up a 04 ctsv (ls6) and id like to do a twin turbo setup on it. im going to stay with a stock motor for this year(600ish rwhp), then do pistons and rods down the road. so id like to just buy good parts now so i dont have to buy things twice when i turn up the power later.
:manifolds
i will be making some custom sch10 tubular manifolds.
:wastgate
pt46mm x2
:turbo
this will be a street car so i dont want to go to big here and give up spool for over all power.needs to be v-band in/out (only avl. in .63 or .82) the 3 turbos i have in mind are the billit. 5857,6057 and the 6262.
:12 volt oil pump
i know the turbos will be to low to just drain back to the pan with out some sort of pump. i have no idea what will work best here
:fuel (e85)
i alredy have 2 bosh 044 fuel pumps, sump for the stock tank,-8an feed line, and fuel lab 100 psi base regulator.
:injectors
i have 4 fic 2150cc injectors. should i just buy 4 more (750$) or sell the ones i have and get 8 smaller fic injectors?
:tranny
stock/rebuilt t56 with billit keys 1-6, steel 3-4 fork and brass shift pads 1-6
:clutch
rxt twin/steel flywheel combo
well thats my plan, any and all help would be appreciated.

I'd say at least the 6262's with 82ar's. Pick up 4 more injectors. Mount the turbos high enough for gravity feed. Find a good tuner to get those injectors idling. Minitub that thing and call The Driveshaft Shop for some upgrades.

I prefer to select the smallest turbo that will still meet the max horsepower goal.
A pair of 5858 CEA ball bearing would kick ***. (.63 v-band)
I don't think the 5558's would have any better response. (at least they didn't before the CEA turbine wheels, 5557 vs 5857)

Im on the fence too between 58/58's and 62/62's. 6.0 w/rectangle port heads, auto with converter 1000lbs less than ctsv. Lots of street highway, 1/4 and standing mile. I think 58I compressor will choke my combo.
