only some of the 20VE springs are stiffer. Certain years I guess... The N1 springs are the softest iirc

correct, that's why N1's have softer springs than 20ve's it's the ramp angle of the cam that has to be focused on.

of course the next question should be why does the N1 have such a different ramp angle but that's for another thread.
