LS3 turbo help
I'm building an LS3 for my '91 with goal being well over 1K hp (built a 1,350 hp 4.6L Mustang for a buddy, I want to beat it now).
I have access to some decent size turbo and I'm planning to run twins, but I can't find enough info on either to know which to run.
Both are B/W turbos.
The first is the one I'm leaning toward because I know the stock engine application runs at 20 psi just cruising around town.
1st:
S300AG072 (Borg Warner P/N)
0.55 A/R compressor
0.80 A/R turbine
2nd:
S2EG070 (Borg Warner P/N)
0.50 A/R compressor
0.70 A/R turbine
If you were building this engine, which twins would you use?
(Yes, I know both are made for 7L diesels)

Re: LS3 turbo help
You need to find out what compressor whee diameters are and what turbine wheel diameters. I googled and couldnt find anything on those. Only thing i found was S2EG070 turbine wheel listed as 60.5/69 mm which imo is on small side for an ls3.
I like to see 64/74 p trim type turbine.
Regular automobile based s300 series in the 66 mm compressor range is ideal for twins. They are like 650-700$ i think. I would go that direction
