the blitz turbo kit uses VERY nice turbos, the KKK K27 turbochargers, which happens to be the same turbos used on the RUF porsche CT3... however the issue is fitment, they don't fit without some major modification on either the supra or the Z, should be capable of 500-600+ rwhp depending on tuning and modifications however... Blitz japan has a RX7 using these same turbos running low/mid 9s in the mid 140s, it uses a Jerico air shifted transmission though.
