hoses
 

what are those hoses called on the back of the manifold (intake mani).....

Also whats the diffrance between d15b7 pistons and d16z6 pixtons ? ;)

Re: hoses
 

fuel lines or vaccum lines how about a better description.

Re: hoses
 

vaccuum hoes ;)

Re: hoses
 

b7 pistons are domed and z6 pistons are dished yO!

Re: hoses
 

is that why the z6 makes higher compression ?

Re: hoses
 

Domed pistons make higher compression in the same motor as opposed to dished pistons which will lower compression. So it must be something else.

Re: hoses
 

they are different cc's, the z6 is 34.6 and the b7 is 38cc.

Re: hoses
 

so which stock d series pistons yeild a high compression ratio ?

Re: hoses
 

just put sand in the intake, when it gets in the combustion chamber it fills up the pistons and makes them higher compresion, not to mention you will also have a nice layer of silicone protection on the top of your pistons O0

pm7's put of a dohc zc or the p29's out of d16a1-8-9, any dohck d16 piston will make high compression in a sohc d motor. why you planning on an all motor build or what?
