how much boost are you trying to run.. higher boost 14+ i think it would be fine under that you may have a small ammount of creep... i mean its only a 2.5L :)

hmmm, maybe marginal based on creep issues I've read about but I am NO expert at all on that motor/turbo combination. fwiw on my 2JZGTE I am now installing a phr stg1 on a cast mani that is moded to fit a 60mm HKS GT wg.

I went from a HPF 50 mm to a HKS 50 mm with small problems and my Tial 44mm has been a blessing. I am a 2JZ but my turbo is a 76 GTS. I am sure you will be fine with that setup.

with the sp61 you will be FINE at holding boost. Wade Tobin who has a 7mgte mk2 has a t61 with tial 38mm an dhe has no problems wat so ever. He also made over 420rwhp last time i checked. :)
