i think you have some wires crossed. the only H23 vtec was in an SIR-T accord wagon over in japan. the H23A1 engine is a DOHC non-vtec engine here in the US. which was found in the 92-96 Si model. there was no vtec model shipped to the US in 92. the first year of a vtec prelude in the US was the 93 model, using an H22A1 engine. the current vtec engine is an H22A4.

93-96 H22A1 - 190hp
97-98 H22A4 - 195hp
99-01 H22A4 - 200hp

there's some weight difference between the body styles and the SH models. but really nothing to significant, nothing a good stripping out of the interior couldnt take care of. people will say the 93 VTEC was the fastest, because it was lighter, but in actuality its only lighter by like 100lbs or so maybe. same goes with the non-SH and SH models in the 5th gen. if i had a choice i would buy a non-SH 5th gen and put an aftermarket LSD in. it would handel better and prolly be cheaper.
