That DOHC being the Ecotec this is quite a little engine!
Check this out:
For a 2.2L DOHC 4banger WITH NO VVT! (OMG HOLY CRAP)
that is a freakin FLAT torque curve for such an engine... Honda can't touch that.
I like the Ecotec, and when it gets supercharged, you gotta see what its going to do to the torque.....
Its funny though... GM has the Ecotec, yet people still claim GM is behind Honda...
the Ecotec can be built up to 1000HP... it is all forged internals (IIRC) and the stock bottom end can support around 400hp or so.
If I was buying a 4cylinder, you'd sure bet it would be an Ecotec.... this engine is so advanced that they were able to help the DOHC not only make this a decent engine for running around town, but also high revving HP.
This is among the very few 4 cylinder gasoline engines used in a car I actually like... alot.
