ENG: diy plenum spacer

you are correct about the removed butterfly valves from the iab plates. you will lose torque and gain top end power.

If you remove the butterfly assembly, then you can remove the black box under your intake runners and their corresponding vacuum lines. Not needed, but if you're someone like me, I like having only what I need. Just less stuff to have to look at lol.

You can delete both the egr and the fitv. and the iac, and the air boost, etc. You can remove any "additional" items to your basic engine without severe trauma. You will sacrifice a DD engine with comforting features, for a clean ass intake manifold.

You sir are my new best friend. If it runs and does so without risking hurting anything, i'm happy. The manual I had on my car was stolen from me along with alot of other stuff when I moved back to Florida so now I have more questions for you. If you ever have time and have a camera, if you could take pics of everything and have a description of what is what as far as the valves, iac, air boost and the rest that I can remove it would be wonderful. As you said "a clean ass intake" is exactly what i'm going for. myspace.com/brandonsilcox or brandonsilcox if you have myspaceim.

Also how much low end would I be losing? I mean will I have trouble pulling out in front of traffic on the highway and it run like a Festiva until a certain RPM or.....................lol.

u see i like people like u
i hate the buttlerfly drama bullshit, seriously i feel that for the look that it gave my manifold i didnt sacrifice shit, the bitch still pulls (btw f22a)

here u go guys (strut bar doenst let u see it that much)

I CANNOT find an H23 anywhere around here. None of my local junk yards have one. I found one but he wants to sell the engine as a whole for a grand. I guess i'll have to order the plenum or something. I'm also thinking about cutting out the center of my spacers since I won't be using the butterflys. I may do some work to the opening on the runners too but I need a different grinder. When you double stack the spacers is everyone just using permatex to seal it or did you buy multiple gaskets?

questions anybody

Not really a question... but please add your input.

I just finished installing my A6 runners with two IAB plates (with the stupid butterflies removed) with a H23 plenum and TB, along with a Bisi Level 2 cam. It feels like it has no getup and go until it hits 3.5K and up, at which point it becomes a rocket ship.

So right now I am thinking about dumping the two IAB plates and running it that way. After all this is a daily driver and this wouldn't be a problem if 75% of the traffic lights were green instead of this stop and go crap...
And of course I just haven't felt like playing with it in 18° and colder weather...

And a side note, lack of a FITV in this weather SUCKS. Getting this thing to idle is a hell of a trick now and again, haven't felt like freezing my butt off to hook it back up...

I would say it is most likely the cam powerband. There were no such issues with a stock F22A6 cam, unless you have other issues.

If it's the Bisi level 2 cam would level 1 or possibly the Delta have better low end? I plan on getting a new cam and was curious about how those three performed.

I would talk to Bisi about that. I can promise he knows more than I do.

You should buy both complete manifolds and sell me the one you take the spacer of off. I have two spacers and the a6 runners but I need the rest of the stuff.

got a question, which exhaust bolts are you talking about, and when talking about compressor bolts are they from de a/c compressor?
