Turbo size
Turbo size Hi guys I'm looking for a turbo(s) for my forged 5.3 build. 317 heads, wiseco pistons, 8.3:1cr, cam is Howard's 224 230 @50 .609 .604 115 lsa. trying to spin it to 6300ish RPM. looking for 900-1100 for a street car, running a mix of 93 and e85. i think 66s will get me close, I was thinking of twin s366s but I can only find them with .91 a/r housing, looking for a quick spool, so I think I would need a .68 housing or something like that. I'm sorry if I am missing important details, I have not started fabricating a hot side, was thinking 2.5 inch pipe but will take suggestions for turbo(s) and turbo advice. thanks.

If I was going twins on a forged engine and only shooting for 900-100, those are the turbos I would pick.
With stupid low compression, that cam on a 5.3, and a pair of .91 housings, you should probably expect to be able to take a nap before you make any boost.

why twins for that power? id go single and call it a day. and definitely get a better cam and drop nitrous. I never understood the point of spending that money on a nitrous kit to bandaid something.

Nothing wrong with the cam if you already have it.
As for quick spool....and 1100hp. Those turbos are a bit on the large side for either of those goals, even more so on a smaller 5.3
A Pair of the smallest 362SXE's would spool a lot faster and make 1000+ with ease.
And you can get many different turbine housings if you look although the normal 0.88 open would cover you, or if your pipework is all divided then you could use a divided housing

They would spool slower with similar power potential to what I stated.
Unless you're flat broke, I just cant see any reason to use the older cast wheel stuff vs the better billet wheeled units. Yes there is a price difference...but it isnt that huge.

Or these ( plus turbine housing cost ), almost same as above
