I been doing alittle research on some turbo's and I now have a short list, these are T04z T04r GT4094r GT4088r. Now will any of these make 1 Bar of boost before 4000rpm on my 1.5j, or should I consider a GT35 series turbo?

Here is a boost/rpm comparison which I got with the .84 TO4Z, (2jzgte head) with head work, 272 deg cams, I'm not sure if boost would come on earlier with 256 or 264 deg cams as you would make more off boost torque down low. I remember it being a bit more responsive down low before I changed cams, intake plenum from stock but only saw 450rwhp. But I am very happy with the TO4Z as it is, also had the rear housing, manifold and dump ceramic coated.
I'm in the process of setting up a surge tank with a 1000hp aeromotive fuel pump and upping the size of the fuel supply line, then going for the 600+rwhp

AT the moment it looks like it will be a GT4088r .85 hot side. I've seen a couple of dyno graphs of a 1.5j with similar mods making 18psi @ 4000rpm which is what I'm looking for.
