Questions about turboing the 5S-FE, Some stuff that I didn't find clear in the FAQ's Options

[GotToyota]

Hey guys, I'm looking into possibly turbo'ing the car a few months down the road. I read the FAQs, but I was confused about what parts I actually need. Here is what I came up with as far as parts:

New, lower mileage motor
3S-GTE oil pan and drain lines
3S-GTE 2 bar map sensor
3S-GTE Manifold/downpipe
CT26 (twin entry)
MK3 Supra N/A injectors
MK3 Supra intercooler
Intercooler piping
SAFC
Boost controller
Boost gauge
Oil pressure gauge
Headgasket

Now, here are the questions I had. Why must you use the twin entry CT-26? Does the single entry (aka Supra) CT-26 work? Is this because of the 3S-GTE manifold? If I bought an aftermarket 3S manifold, could I then use the Supra CT? I ask because I have access to a few of these.

Also, what is needed concerning the oil and coolant lines? This is where I get confused. I would like this to the as budget of a build as possible, but at the same time be reliable. I would plan to run 6-8psi or so.
