After an exhausting 3 month wait my new twin scroll FP HTA73 green is here. it will be replacing the 20g in this thread: 1st twin scroll 20g on DSM !!! (EVO 10 turbo)
1. looking into inlet.
2. CNC ported shroud to stock cover
3. custom FP inlet to match ported shroud
4. HTA73, 5 blade EVO 9 FPgreen, 20g, and 16g
5. HTA73 , 6HSL2, 5H
6. top=20g/5H. middle = FPgreen/6SL2. bottom = HTA73
7. HTA73 almost fits in 20g cover.
8. 16g gets lost in 20g cover.
