..... T04E 57 on the compressor side .....
Wait.. They can make bigger turbos for these cars than the TA-33? I thought the TA-33 was the biggest?
How about a Billet 6262
I just looked up a 6262 turbo and the first thing that pops right out is the inlet of the compressor. There's no bolting on the throttle body to that casing. Maybe something can be fabricated, but it'll be much more of a challenge than a TA series.
