ok i just checked my messages and he called while i was on line a lil bit ago, and he said it's a d16a1. just for the record a D16a1 and a ZC engine are 2 very different engines that look simular. i'm not trying to be a dick or anything, it's just since so many people in here think that both motors are the same, i'm trying to let you guys know that there are big differences between them. things like the block, mounting bolt patterns, head, crank shaft, cam gears, and valve cover just to name a few. lol
there's always guys out at the races saying that i have a ZC in my ugly ol teg, but it's a d16a1 !!!!! lol
