I have three intake manifolds. one for my D15 and two for a D16.. one is a Y8 and the other a Z6. im doing a mini me swap on my 93 DX and i am wondering is it really worth the extra effort to swap everything over the the y8? or even the Z6? or can i just reuse the D15 intake. i just don't see any diffrence between the Z6 and the D15.. any help would be great. thanks

 

which d15?

 

the y8 is suppose to be the best flowing d series manifold. Its not that hard to switch it over. If i had it i would do it. But the z6 is also better than the d15 one. The main reason is because of the TB being bigger.

 

D15B7

 

I am guessing maybe a gain of only a few hp or so. It will help on the high end tho.
