A spicy winter project Twin Scroll conversion and more!
Planned this really long time ago, now its time to make it shine.
I m not gonna only put Twin Scroll turbos(E63 turbo) on, its hybrid bigger turbos.
Update#1 initial setup: Pump gas 94AKI ,STOCK HPFP LPFP, With WMI:
Car was making 490 WHP on stock tune stock turbo with catless downpipe.523WHP on this turbo with stock tune after 5000 RPM I seen it over boosted a lot, even Wastegate requested fully open(5% duty cycle) still over boosting, then ECU cutting the ignition also closing throttle to bring down the power(From graph after 5500 rpm we can see it going down).
850WHP is the GTs stock HPFP limit with WMI.
Upgrade HPFP is on the way

Reason: updates.
Would you mind please listing all the Parts with Model Numbers, etc necessary to complete this conversion to Twin Scroll setup?
I'm sure those looking to do the same would greatly appreciate it.
TIA

Besides the manifolds, just buy all E63s turbo oil& cooling lines heatshield, some little extra work on driver side downpipe(driver side twin scroll turbo sit back about 11.5mm compare to single scroll), Passenger side evap hose delete or modify return location, Passenger side PCV delete( to catch can) or modify return location. Passenger side charge pipe fitment are very bad, but you still can force them on.
