So I'll start this off by asking what have you modified on the turbo to make it more efficient in some way?

Simply a dual 2.5" Maf-less system I built for it. I am wishing now that I used 3" as I may have left a few hp on the table. I welded 2.5" v-bands to the turbo inlets as to minimize the inlet turbulence that a couplet could induce. Took care to make sure all inlet pipe fitment was perfect.

I personally feel that if the customer wanted to truly max out the turbos by freeing up some restriction that still exists in the inlet & charge pipe sections that I could get another 25-35whp out of them. Car is still on the factory intercooler & intake plenum after all.

You're in Inlet pipes might be 63.5mm which is great but you're inducer is like 47mm from memory.

Got a pic of the cooler, Nismo is not factory and there is two versions with one being far superior to the other

Looking at the parts list I would say the exhaust and ID1000s are the most limiting factors and would guess a realistic 400-420rwkws and give or take 130-135mph

List says Nismo cooler, factory cooler starts to measurably pressure drop from around 350kw, 500+rwkw on a stock cooler is where I call mythbusted

Nismo intercooler hard pipes

Car made 490whp on 13psi...... Mustered a 507whp pull at about 15psi but the 93 octane pump gas was the limiting factor.
