as Ryan has said above^^^
both our cars have been through varies stages of turbo setup ups (myself 3rd), and the reason we have chosen to go a GT35/40 is because we both got use to the power the other turbos delivered and wasn't worried about lag
even though my engine is a forged built engine with cams...etc the turbo isn't much laggier (i prefer the big hit of boost)
i think it all comes down to how your car is tuned by the tuner aswell and what supporting mods u have
As i said earlier Ryans car is the best example of a rb25 i have seen of how to pull 300rwkw through a internally stock engine on BP ultimate
i tried but unfortuanly my tuner at the time leaned out my car on the dyno and blew piston 6 ringland, hence my rebuild
like Ryan im also willing to take whoever for a ride to feel how a "DAILY DRIVEN r33" 350+rWKW skyline feels like
both are cars are very STEALTH, just by looking at them from the outside you would never pick it
