a1 to a6 i/m swap

[accordkid16]

does the a6 i/m flow better than the a1 i/m? and if so can i bolt it on using the a1 IAB?

[92accordkidd]

to me the a6 flows better than the a1 and it can bolt rite on

[visualpoet]

Yes and no: the a6 IM flows better, but there is no IAB on the A1 manifold. You'll want the entire manifold from the block to the throttle body. You can also use the H23 IM or a combination of the two.

You've surely been a member long enough to learn to use the search function; there are several threads about the a6 IM swap.

thats true bro the h23 im is better

thats true bro the h23 im better

Is that a question or a statement?

Please make sense when you type... if we can't understand you, we won't be able to help you. Or rather, we won't bother trying.

ive searched and didnt find what i was looking for. I just want to know if i can bolt it on with out using the IAB or is that a must have, and if it will give me any better throttle responce..im not running the a6 cam or e/m.

I'll spoon feed ya!

The A1 is only a single runner design. The A6 is a dual runner design, thus you can't bolt upper plenum of the A6 onto the A1 runners.

The H23 and A6 have the same bolt pattern, but different plenums (H23's is larger). Both bolt up perfectly for the A1, A4, A6 block.

The H23 has longer runners then the A6 by about a half an inch.

The most common combo seems to be the runners off an A6 and the plenum off an H23. You can go with a single IAB plate or gut one and double stack them OR gut two of them and double stack them, or completely remove them. Quite a lot of options.

The A6 and H23 don't have the same runner design, but the bolt pattern and port spacing is the same for the two manifolds.

would it just be a better idea to order the bisi gasket for my a1?

Well yes, let me correct that.

They all use the same gasket, so it wouldn't hurt.

They're two completely different parts. (as in the gasket and the manifold... not that the manifolds take different gaskets...)


This is why we don't waste time spoon feeding people... because the slightest hint that it might take a little time, effort, and thought to do, people get scared and give up.

I shouldn't have even tried... lesson learned.

[Extacee]

hmm, makes me want to go ahead and do that!

[accordkid16]

im not giving up thank you very much im doing some research and looking at a few of my options.
