I am not saying that the smaller displacement engines are easier to "bolt-on" mods. The truth is that the SR20DET and the RB26DET were designed as high performance engines. Ever wonder why Nissan's supercar had the I6 and not a v6? The VG series engines were made to haul family cars and terranos (pathfinders). In fact the latest iteration of the VG, the VQ35DE is already hitting it's upper limits of it's capabilities.

Displacement comparissons? Sure, an SR18DE will make less power and torque than an SR20DE. Same overal architecture and performance design but the higher diplacement will have more power.

Now let's look at different designs with different displacements. Compare the old ford Cobra 5.0 versus the current Cobra 4.6. Guess which is a better engine in overall power and emmisions?

Displacement is not the sole measure on the potential of an engine.
