AT Turbo d16y8 with a Z6 head?
#5
Re: AT Turbo d16y8 with a Z6 head?
i dont think there is that much of a comp diffrence to go through the troubles of changing a head
the y8 has a squareish combustion chamber and a littler lower volume thus a slightly higher comp ratio
here is the diffrence between the two engines
96-00 EX (D16Y
127 hp @ 6,600
107lb-ft @ 5,500
Redline 7,200 rpm
Bore X Stroke: 75mm x 90mm
Disp: 1590cc
CR: 9.6:1
In Valve Dia: 30.1mm
Exh Valve Dia: 26.1mm
Cam Lobe IN/EX: (mid)38.274mm/ 38.008mm
92-5 Si/Ex (D16Z6)
125 hp @ 6,600rpm
106lb-ft @ 5,200rpm
Redline: 7,200 rpm
Bore x Stroke: 75 X 90 mm
Disp: 1590cc
CR: 9.2:1
In Valve Dia: 30.1mm
Exh Valve Dia: 26.1mm
Cam Lobe IN/EX: (mid)38.107mm/ 38.008mm
0.4:1 diffrence just in the gasket and head, if you got it together my advice is just leave it alone, i would only ---- with it if you are taking it upart for a build anyway. Some people will argue the z6 will flow better i have seen no proff of this so i'll let the ricers duke this one out
