Ok, not gonna pick on you anymore. I just realized you were new here.
Anyways, As far as I know (and I could be wrong), there wasnt a 2.3 HO. But the 91-93 2.3l stang engines had 105 horses due to I think a roller cam. the ones pre 91 had only 88 horses. So if you wanna look at it that way, the 91-93's had a "higher output" than the pre 91's. But I still wouldnt call it a HO
As far as turbo HO's, I think what i said above should answer that.
