rb26 torque differences

[benjiman74]

When reading the latest issue of Zoom last night, their article "street tuner" quoted torque figures as follows:-

r32 - 353nm @ 4,400 rpm

r33 - 368nm @ 4,400 rpm

r34 - 392nm @ 4,400 rpm

Can someone identify the differences between these donks that leads to the variance in torque?

My understanding was they shared the same components barring the r34 which had b/b turbos. Maybe ecu differences?

basically ecu differences, slight improvements in exhaust and inlet also may have helped
