no, because both engines were welded together side by side and use a common crankshaft, making it a V12. it does look like it has 4 turbos though, which is nuts :shock: .
as a racecar combining two rb26's makes plenty of sense, assuming enough chassis and suspension development is done to compensate for the extra weight. those super tuned skylines with just the inline six not only have huge lag, but their power curve is incredibly peaky, which is very bad for a racecar. the combination of two rb26s will give it not only a big power boost, but a huge torque boost and much more linear power delivery.
I'm a big fan of this one, probably partially because I really liked the TVR Speed 12, which essentially did the same thing with their speed six engine. of course it also has 4 turbos, which is.... awesome. must have taken a lot of money to develop this though, since the crankcase and crankshaft must be totally bespoke. it probably runs off two ecu's as well, one for each bank... again, like the Speed 12.
