Okay just wanna know if a d16z6 manifold can be ported that big to fit a 68mm throttle body. The motor is a zc block, p29 pistons, z6 head, oversized valves, comp srpings. so its not stock. want a 66 or 68 but wanna know if i can even bore the manifold that big.

 

no. even the sunk2 one only allows 4mm over it's 70mm plenum, stop wasting money on that set up.

 

B series guys hate so much. Its a question. Everyone can build want they want

 

yes that's true but you'd have more to spend if you know power to cost ratio just buy a skunk2 manifold and get a 70mm tb problem solved.

 

Im trying to avoid that manifold. My friend works there so i can get a deal but the runner ports dont even match, they are smaller then stock -_-

 

I know peope have ran a ctr on the z6 manifold so ill probably end up doing that. About the cost. Ive spent about 1800 on everything, not including stuff that i did before i decided to add the pistons

 

total opposite for the b-series ones.

62mm is the ctr tb bore. and your z6 plenum will be 60mm.

 

Yeah skunk2 i question sometimes. Isnt the z6 56mm? I could be wrong
