Thinking about doing twins
Thinking about doing twins Originally I was planning on a 7875 turbo, but space of fitting the hot side to a merge may become difficult due to space. Now I'm thinking of twins, will be easier to package due to tight space around my steering shaft.
Im going to rebuild my 5.3, boring it .020-.030 over. This will be a 90% street driven truck. I'm looking to get to 500-550rwhp in street trim, possibly trying to get to 650 turned up.
I've been looking at a few different turbos from CXRacing. Looking for some input from some experienced turbo guys.
Turbo #1
t3/t4 to4e
.50 a/r compressor
.63 turbine
Turbo #2
t3/t4 to4e
.60 a/r compressor
.63 a/r turbine
compressor wheel 3" exducer,2" inducer
turbine wheel 2.2" exducer, 2.58" inducer
Turbo #3
gt35
.70 a/r compressor 61.3/82mm wheel
.63 turbine 62/67.8mm wheel
t3 flange
Turbo #4
gt35
.70 a/r compressor 61.3/82 mm wheel
.82 turbine 62/67.8mm wheel
t3 flange
Any thoughts for my goals? I was leaning to turbo #2, but I am hoping others with more experience will chime in.

No opinions? I know there was a thread of a member using a t3/t4 50 trim, spooled fast. I know there is a 57 trim available as well. Do you guys think the 60 trim will be to big? I plan on running a BTR stage2 turbo cam. Or would a 57 trim fit the bill better?
