when useing a z6 manafold i noticed that the that the throttle body dosnt have the vacume control modual like the mpfi d16a6 throttle body the y8 manafold also has this prob . This wouldnt be a problem but the throttle body's dont match up. is there an easier way to fix this problem then drilling the manafold? how is the flow on the d16z6 as compaired to the d16a6? is it worth anything? i know i am for better off going with the y8 manafold. FYI this is going on a 4th gen civic with a z6 head & block. and i supose i need the vacume modual on the throttle body? is it used for idle or somthing? thank you

i have a Z6 longblock including the Intake manifold... i am on OBDO electronics and using a PM6..
i dont have no problems at all with the IM.... IMO i dont see why u wouldnt use a Z6 manifold over a A6.. they are soo much better design.... just use the Z6 MAP sensor and u good to go... everything else bolts up

 

im useing the a6 intake because i have a jg throttle body for it and do you know what im talking about when i say that vacume thing? did you just not do anything with that do you have trouble wile at idle?
