I'm just curious, all of those VVT stuff looks really complicated and alot of electronics. Would you guys think that if something broke down it would be difficult and expensive to fix? unlike a non-VVT ecotec (less stuff there is to break down)? I personally would buy a normal 2.2 ECOTEC or invest some money into a longer warranty to fix it.

Exactly. Honda's been using Variable Valve Timing for over 15 years (they call it VTEC) with hardly any issues to speak of.

Its proven and reliable technology, and shouldn't be anything to worry about on the 2.4 SS.

 

actually vtech isnt the same as variable timing

vtech comes on at a certian rpm , and changes the profile of the cam for more power

vvt , actually changes the cam timing , but does nothing with changing the profile

 

The trailblazer with the 4.2 uses VVT on the exhaust cam. We have had "0" problems with it so far (used since 2002)
