Keep standing then! The 4.6 is narrower than the 5.4 due to the shorter deck height of the block (shorter stroke).imugli said:Isn't the 4.6 to wide to fit into the BA engine bay easily? I know Hilliers put it in the 300+, but I didn't think it was viable on a high volume basis...
I hereby stand to be corrected.
What Ian says is true, but only for the same gear ratio, if the Mazda revs 50% higher and has gearing to match (ie same road speed at 9000rpm as the Nissan at 6000rpm) then they would accelerate at the same rate.
PS that is just a hypothetical, theoretical example. I pulled those figures out of my... I mean from thin air! So don't argue about what the gearing actually is. I agree entirely with the point you're making (don't overlook torque) but there is more to it.
