If this question's already been answered please direct me to the nearest thread? I can't seem to find one ><. I have lost many a night of sleep over this.
And how's this 2.4L Ecotec coming along? Are our LD9's toast or is it hype I hear about this new Eco?
Followup: Did some searching while at work. Found a page on the LD9 if anyone cares it's http://www.quad4forums.com/darkfox/Spec.htm |
No the 2.4 EcoTec isn't hype it will appear in a staunr and a pontiac later this year! Shush though! It's not actually all that different from the ld9!!
The Ecotec 2.2 has .5:1 more comp ratio (10:1). The cam lift is good but the duration very short which makes me think that the cams will be more or less shot before the car hits 100,000 miles! It's alu block and head on the eco and the block on the ld9 Iron! It doesn't really differ too much in design and some people think it's a re-worked LD-9. There is only one ecotec in the states currently if you could the destroked ss/ s/c and ion redline motor as the same. However in Europe where the EcoTec has been around for about 7 years there are 1l 1.2l 1.4l 1.6l 1.8l and 2.0l variants! The 1l being a 3 cylinder! Personally I hate that thing! (1l although the car it powers is smaller than an aveo)They have been reliable in the european forms but I don't know how similar the achitecture is to the 2.2l version. My buddy has a screen saver that shows an Ecotec going together it's good and very similar to the ld-9n from that!
