For me the HTA3586R is out of the question.
It's very hard to choose between the PTE HP6262 and the GT3788R. For me it would be up to which one took less fabrication work to make it fit. The GT37 is going to take work to get the V-band on the downpipe. I'm not sure what it would take to get the PTE HP6262 hooked up. =/
Apparently around 40-45 psi the PTE HP6262 has made around
780+ WHP on some 2.0 liter engines.
