I am looking to build a D-series motor and was wondering what setup to go with. I hav a a6, z6, and y8 block and a a6,z6,y8 head and manifold. I was wonder what would be the best and strongest choice to use for a all motor single cam. Also, what pistons, and rods should i run?

d16a6 shortblock w/ y8 head

IMO this is the best setup.(for d sohc)

 

d16a6 block, y8 head, zc pistons, compcam 59300, intake, good 4-1 header, good exhaust.

 

I thought the z6 had the best head and the y8 had the best intake?

 

From all the research I've seen, the A6 head flows the best, then the Z6, then the Y8. For a street motor, its fine to use any of those. For an all out race motor, A6 all the way.

 

well the a6 isnt even vtec and its old as ****,

i wouldnt believe for a second that it flows better than a z6 or y8

 

we need not get in the v-tec VS non v-tec


we already know who wins

 

I built a Z6 with Aries 11:1 pistons, LS rods ( machined of course), JG head, with 85VT80 cam, JG TBI, rechipped ecu, Y8 manifold and a piece of **** header. I ran 14.1 in a 93 hatchback with 20x14x8 MT slicks. Not bad i think.

 

sweet setup allmotord16z6.....the y8 just needs a port job on the intake side to make it flow good but the y8 has a smaller combustion chamber yeilding higher compression.

theyre both SOHC POS motors....
they'll perform about the same with a HUGE CAM.

 

well i appreciate all the thoughts, just keep them comming

 

Thanks man, it's not bad. I was looking for more power so i pulled the motor and now i'm getting a new one done up. Can't give alot of details but it should be real intersesting in the NDRA Comp 4 class in Houston. SOHC All Motor should turn some heads.
