The SR20VE is a 2.0l and the SR16VE is a 1.6l. There is better versions of both the VE motors. There is the SR20VE 20V which there is about 4 of in the states and they only came in the p12 G20s in Japan with a 6 speed tranny. Then there is the SR16VE N1 which came in the VZR pulsar which is a hatch back of the B14. It made 200hp from the factory because of a nissan PP job on the head along with bigger cams and better S/R. The N1 cams are the best factory cam out right now for the VVL motors.

You can put a VVL head on a 240 you just need to put it in a s14 if I remember correctly.

I am building a drag b14 with a fully build VE in it. I better S/R and a custom cam set up. Should be able to rev to 10k no problem.

If you have any more questions pm me.
