2tongues I have driven one only the once and was impressed with the little power boost, bit like a tiny turbo.
Is there a way to get the lift to operate a bit earlier?
There is a system for the Vtec Honda engines, that brings the "lift" in earlier. I can imagine its controlled by the Ecu, maybe a Uni chip or piggy back ecu could be used?

I wonder where you could get one of them from ??????????

Welcome to the club and by the way you should never buy any car that Anees advises you to :p

But he was trying to persuade me to get a Subaru, but don't think the boss would agree!!
Anyways, I'm happy with what I got, its had the major mods done for me, so I can concentrate on other things now...

I think it could be possible, but read on....
there is a reason that Toyota put the lift so high. The reason that lift is set at 6k is because it doesn't make more power than the first cam at lower RPM's. If you lowered the 2nd cam engaugement point to 5,500 rpm or lower, instead of getting a more linear power band, or getting more power earlier, you will instead get a big power loss when lift kicks in. The car would bog down.
No one has been able to crack the factory ECU to modify the lift engaugement. The only device that allows you to adjust VVTL-i is the Apexi Power FC. Like mentioned above, lowering the RPM that lift kicks in results in a power loss instead of a gain. A member of NC.org (M-Spec) lowered the lift to 5,500 RPM with the Power FC when he was tuning his car and had dyno proven power loss because of it. Instead of lowering the lift engaugement to try and stay in the power band, he ended up raising the fuel cut off point so he could rev higher.

Only reason I said that is because he / me wanted me to get an Evo but my boss would not let me :ohmy:

Probably the easiest option would be to fit a 7 speed gearbox to keep that narrow power band in the sweet spot, one reason why Mr T fitted a six speed box into the T sport, and now other manufacture are fitting 8 speed boxes., just to keep them on the boil
its a complicated subject if your not fully aware of the operation of the internal combustion engine and the physics that go with. its all to do with valve lift duration, timing, air/fuel ratio and to get this to operate in harmony and to extract maximum power then exact science has to be adhered to, as newdriftking has pointed out, get one aspect wrong and you can loose power due to things flame quench, where as the spark propagation or flame can actually go out momentarily and loose power, compression being lost out of the inlet or exhaust port low speed air inertia etc etc.
