For those who don't know, the D16Y8 came in the '96-'00 EX (the 'EK' chassis) while the D16Z6 came in the '92-'95 EX (the 'EG' chassis). Both cars are classed in ITA at the same weight, 2305lbs. The engines are almost identical, with the block and head molds being the same, but IIRC the Y8 is factory rated at about +2hp over the Z6.
