Where are you reading this? I need to see where this diarrhea is spreading!
20V advantages over regular SR20VE....
1. 70mm throttle body (60mm on standard SR20VE)
2. full eight-counterweight crank (four on SR20VE so the 20V is heavier but the 20V is also better balanced for whatever application the end-user wishes to use it for) Higher revs want balance more so than lightweight for speed.
3. 34.3mm inconel valves with 5.5mm valve stems that are cut back from factory to further decrease friction (lighter and less restrictive) "port sizes are the same on exhaust, but smaller stem valves, inconel exh valves. the intake port design is better aka for more for mid-range torque" -Greg Vogel
4. The 20V head flows the most out of any factory Nissan VVL head. The ports are the same size, but how the port is designed inside is totally different and more effective than any other Nissan stock, from factory, VVL head. More than the N1 head, ask Charles because he flow bench tested the thing.
5. 11.0:1 compression ratio (vs 10.3:1 on normal SR20VE engines)
20V rocks.
