Hi buddy!
This winter I am converting to a single turbo HKS T04R setup. However, this summer was the first time I could drive my FD freely as it had just been rebuilt. I had kept the stock twins but made them non-sequential.
Here's my numbers and mods that I had:
Non-sequential twin turbos
Streetport
Injectors
Large stock mount intercooler
Fuel pump
Apexi Power-FC
Full exhaust
Couple more things just so the engine was safe running those numbers.
I achieved 357.7WHP with 284WTQ on 16 psi.
And don't be afraid. I am not converting to a single turbo kit because it was unreliable or whatever you may think. What actually happened was; The bolt that holds the turbo propeller hadn't been torqued right by the guys that rebuilt them. It, then, went through the 2nd turbo and the turbo wouldn't spool anymore.
I think sequential to non-sequential is the best mod you can do to a stock FD when it comes to starting to gain horsepower.
Here's the dyno sheet so you get a fair example of the boost range and everything you need to know about max HP with stock twins:

Trust me I am not lying lol. And it is a roller dyno or whatever you call it. 360whp @ 16psi non sequential. Of course not everybody's going to have the same numbers lol. Called common sense... it wasn't tuned by a nobody aswell.

Wow, nice numbers man. Large street port? How much boost? I feel like I could have gotten over 360whp easily. My injectors are way capable of taking 18+ psi.
edit: Those are BHP and BTQ numbers right? So then I feel like it would be around the same as mine. 21 psi! Still alot of boost. happy to see stock twins can go way over 16
