Benefits of going VVT-i? Options

[Random_Stranger]

Ok, so I just found out that VVT-i was like dual variable valve timing for HP and TQ. So anyone know how this is beneficial or worse in let's say a 3sgte engine? As I am aware there is a 4th gen engine that has this VVT-i technology (I think).

(I had made a n00b out of myself with the original posting, so I made this thread up to make up for it in another n00bish fashion, but with more to gain from it than my original thread, so my bad.)

very good info Edophus. And it would be more like the B18C jdm spec motor vs the Beams Redtop. the b18c6 only produces 190 hp.

also if I may add one thing. How much power would the beams redtop lose if you were to attach an egr to it.

The reason why I asking this question is becuase the jdm spec integra type r produces 198 hp at 138 lb torque with a 4-1 header, while the USDM spec Integra type R produces 195 hp at 130 lb ft torque. How the hell is that? I know that jdm spec runs 100 Ron = 94 octane, and the usdm spec engine runs 95 ron = 91 octane in California and 98 ron = 93 octane in other states across the U.S.

So how is that that they were able to bring over such a high reving from japan and tweak it so that it only loses 3 hp. Was it the egr that made the usdm spec engine lose 3 hp, or becuase of the lower octane that is provided here in the U.S?

oh that was the one i meant , for some reason i remembered it as the c6 but your quite right!

corrected i think its a pretty good comparison, my freind had a 98 spec engine (B18C lol) in his 96 spec integra type-r and we both travelled to track days together, my ss3 despite being a bit heavier used exactly the same amount of fuel, i mean we were filling up at the same time and putting in the same amount with only pennies difference, both were tuned to the same level, and one was as quick as the other to the point of putting in virtually identical laptimes, they just both went about it with different characteristics, so highlights the benefits of a vvti engine in terms of its ability to bring performance and economy to the mix.
