Yes, I am an ex h23 driver. I have experienced the change from h23 to h22.
Honestly, the difference lowend is not that noticeable, I will say the h23 actually did feel more torquey in the lower rpms, but its not like the h22 is a slouch... and I hope to get pulleys to get lower end gains. I ran on the p14 (h23 ecu) for a little bit and it felt just like an H23 w/o vtec! So I think the ecu has something to do with the low end, high end power. Just a thought
Even though the h23 might have more low end torque... would I trade my higher rpm fun for low end daily driving goodness? My opinion:
NO!
But hey its all personal preference, some like driving more effectively in traffic, I like to win
Not saying the h23 was slow by any means, I loved that thing, kept me happy

just that when it became non-cost effective to maintain and constantly repair it gave me an opportunity to either rebuild and go turbo or get jdm h22a. I picked the JDM swap for conservative reasons. Plans currently are to go all motor...
I think most h23 ppl are h22 ppl in training, :laugh: that high mileage h23 aint going to last forever, and it won't be worth it to try to make it last either.... oh yea, the h22's don't have that notorious ticking and valves don't have to be constantly adjusted, at least not as much as h23s.
Anyways, both engines are great, both have downs and both have ups, one particularly after 5k rpm :bigthumb:
So lets just respect each other's engines aiiiiite.
