5.3 liter turbo size and e-85 ?

[94RCSB]

stock 5.3 liter arp rod bolts,ls1 cam, what size turbo and injectors do you think i need I would like to keep it non intercooled with 7 to 8 psi is this doable with the e-85 and is 500 wheel horsepower realistic. I was thinking mastepower turbo either t70 or t76 size thanks in advance.

Master Power doesn't make Turbos for the US anymore, but you can get Magnum T70's which are basically MP clones, only probably a little better and you can get them in ball bearing too. A T70 on a 5.3 is a great fit. 43's won't get the job done with E85, your gonna need 60's and a good fuel system. With the right tuning and about 10-11 psi, 500rwhp should be do able.

is this something that a factory 96 to 98 fuel pump can handle or that plus an inline or do i just go for something like 255 walbro

Definitely needs bigger than factory. Travis (bangbangskeetskeet) has a 255 walbro dropin kit that he got for a good price it is really nice maybe they make a similar setup for your obs. Maybe he will pop in with a link.

Check out racetronix for the kit that I got...dont have the link but its not that hard to find. Depending on the power goals your looking at, and the fact that youre going to use e85, you may need more pump than just the 255lph.
