yes and no... it's a 2.5 litre. they took an H22A, bored it to 90mm, then used the H23's crank to stroke it (a billet version thereof). the block had a deck plate installed to accomodate a longer rod to help square up the rod/stroke ratio and improve high rpm performance and reduce side forces within the rotational assembly.
the ideal rod/stroke ratio is 1.75:1 the H23 is about 1.59:1 and the H22 is 1.64:1 or something like that. i had everything written in a build log somewhere, but have had no success with finding them since i moved.
