i am swapping a y8 head onto my a6 block. i have the throttle body for the y8, is there any benefits to it? or can i use my a6 with same performance. just wondering! I searched too

 

probably the same only thing that might be different is the bore even then a slightly biger one wont help much. but if you use the y8 one you gota extend your map wireing to reach it.

 

-map sensor on the throttle body
-55mm vs. 56mm if i remember right.

You have it so you might as well. It's probably not going to be a noticeable difference but you get a sensor off the firewall and a slightly larger throttle body.

 

from what i could remember, the bolt pattern change after 92 but i could be wrong

can anyone verify this? i would like to not have to really swap them out if i dont have to. i am not worried about a 1 mm bore difference or getting a wire off the fire wall. i have given up on trying to make my engine bay look pretty. thanks

thats wrong i had a a6 tb on a d15b7 not sure about the 96+ though.

 

As far as I know an A6 TB will not fit on an intake mani off anything 92+

I'm pretty sure the same. I know my a6 throttle body wouldn't fit my y8 mani and vice versa. I forgot about that in my above post.

Correct, the D16A6 throttle body will not fit on any other intake manifold other than it's own and the D16A1 one.

 

thanks guys!!

 

Doesn't the y8 tb use a b-series bolt pattern? As in if you have the y8 manifold, you could put on a LS tb.

 

b,d,h,and f use the same pattern with in their obd range. I dont know about 0bd1-2 though.

 

Ok, here's the deal.

88-91 D-Series = The odd flange out, largest TB = 55mm
90-01 B-Series = The good Flange
92-00 D-Series = The Good Flange, largest TB= 56mm
H-Series + F-Series = The good Flange.

 

i dont want to make a new thread if i dont have to, so i will bump this and ask if my a6 headers will bolt right up? i dont even care if i lose performanc ethrough them, just want to drive the car with the head swap whenever i do it in the spring.

 

yes.
