I'm runnin the SR40 at 22-23psi it spools great and good power but I really don't recommend the APS turbos. I would either FP turbos the green is super for me the red would be a little much, it is better on the 2.5L. I ve heard mixed opinions on the GT35R some people have said that the boxer engine spools it better than the inlines (4G63s and SR20s) do, if that is the case it would be my choice.
Good luck with the build

I'm gonna see if I can get one special made with the variable compressor vanes and a small enough housing to still get damn quick spool. Then see if they'll sponsor me for a JDM engine/FMIC project (I wish)

well if you are looking for a track monster i would recomend a rotated set up. they are much more effecient and relyable than a traditional set up. and they are very easy to change housings on if you would like to change your set up for differant applications.
i would also run a water injection as a back up. plus you will be able to run 5 more lbs of boost safely.
if i was going to do a huge turbo set up. i would have the turbo kit installed and have it tuned very mildly. that way i could have a chance to get the feel for the car. then after a while i would do the internals, and the crazy boost
