AEB Intake manifold swap question

[slow&low]

I searched and didn't find the answer. I went to put on my AEB manifold on my AWT and low and behold the injectors do not fit. It appears that the injector holders are a different size comparing the 2 manifolds side by side. The injectors and fuel rail don't seem to go deep enough to seal on the AEB. Am I missing something really simple here? I figured it would be a straight swap.

I'd like to know as well. Did you use your tb from your awt?

[dougyfresh]

what injectors?

[PhunkFX]

I just put an AEB intake manifold on my AMB. You have to use the black injector holders in the manifold (AEB injector holders) and you have to use AEB injectors.

Any other injector holders will NOT fit in an AEB manifold. Therefore you cannot use non AEB injectors with an AEB manifold.

This is to my experience. I have an fully functional AEB manifold now. I just resorted to using AEB injectors.

Are you running a big port head?

What facilitated the need to install an AEB intake manifold?

[PhunkFX]

Ported head, spacer, and it was powder coated.

[dougyfresh]

I guess that works. I would have ported the AMB manifold to match the ported head. The AMB manifold has a bigger plenum and the cyl3 leaning isn't as pronounced as with the AEB manifold.

[PhunkFX]

Right. No biggie. I'm quite sure the difference is minimal in all aspects considering I'm not running any crazy huge turbo. But in reality, I wanted it because it looks nice :)

what injectors?

Audi TT225 injectors.

Since when are there different injectors for AEB vs other 1.8t motors? I was under the impression all injectors were essentially the same. Now I am really confused.

[PhunkFX]

Nope. Just on AEB's THey were the first 1.8T motor for Audi. The entire head and intake manifold are different. Including injectors.

BUMP

quick question on same topic. i got a AEB intake mani that i painted and im about to install on my AMB. what did you guys do with the plate that carries the N112 and N249 valves??

zip tie it to the wiring harness and that coolant hard line (for the heater core) near the oil filter assembly.

awesome. thanks doug

one more thing, is it worth it to get this or just a regular gasket?

[Sales@RAI]

I have the 034 one. I suppose it works, wouldn't be a huge difference, but its something

[onceover]

Up!

I'm running into a similar problem trying to put an AEB intake on my car.

It seems as though the spacing on the AMB fuel rail is different, making the injectors on the AEB manifold not seat down far enough. Has anyone else run into this problem? Do I need injector spacers or something?

[evo_ski]

Any more details on the required changes, IE injectors, fuel rail, etc. Onceover, what all did you end up swapping out?

[onceover]

Just ground the fuel rail mounts down until the injectors seated properly. Alternativley you can buy fuel injector spacers so you dont have to modify your manifold

[Wet0willy01]

Or you could run tall 60mm injectors instead of 48mm short injectors if your tune allows for such option. Otherwise get injector spacers, or (unnecessary) an 034 fuel rail will fit short 48mm injectors on a large port intake FWIW.

[evo_ski]

Thanks guys. For reference I am not looking to build or upgrade anything at all. I am looking at bare minimum stuff to just get the car to run with a new head. I am taking my head to be pressure tested today, but am trying to research a "Plan B" so to speak if they find out my current head won't hold compression. I don't have the cash for a build and am tiptronic anyway, so I just need something that I can bolt on with minimal additional changes and go. I am just trying to find the absolute cheapest way to get my car back on the road. I have an AMB right now and there are a couple AEB heads on craigslist right now for around $400. But if it is going to cost me a ton to get my existing stuff to work with it I would rather just stay AMB.

I am APR stage 1, stock everything else.

Thanks for the help.

[onceover]

If you're never going to build it I would just suggest finding an AMB, ATW, etc head that will bolt right in without having to swap anything.

Yep, I agree with this.. but really think about how long you plan on keeping your car (realistically, every person is different) and what you think you'll be happy with, in terms of power. I see no issue with using a small port head when talking about Sub 350whp. Above that and you start to see benefits of the big port head since it has a better flow rate.

[evo_ski]

My neighbor has an AWP head. I have been trying to research to see if that will fit, but haven't found a whole lot.

AWP is a direct swap and can be found for decent prices.

[evo_ski]

Hmmm, that is very interesting. I am trying to find out some more info now. My neighbor is a super cool guy and would probably give it to me for dirt cheap.

tell your neighbor to magically find another one and hook me up too! lol, I'm sure I'll pull my head sometime next year and I'm scared I'll be opening up a can of worms. Nothing is wrong with my car, I'd just like to have a fresh HG and check out my #2 cylinder since it has slightly lower compression than the others.

necro bump

can someone list some 60mm injectors that are compatible with the AEB manifold? I’m currently using siemens 630cc and they work but I’d like to get some ev14’s back in. The standard 48mm 550cc’s with 12mm spacers do not work, or did not work for me. Do the saab long style 60mm ev14’s fit? What injectors do AEB big turbo guys normally run?

On the AEB, they run the same aftermarket injectors other's use for BT files. I would assume 60mm EV14 injectors would work just as other 60mm, but I would not want you to spend your money on them and me being wrong. If your 60mm dekas work, I don't see why 60mm EV14 injectors won't work. Just going by that logic...all things being equal.

If going to order, order the 60mm length and not the 48mm length (these are the same ones I run, in 60mm length on my AWM IM and high flow rail): https://www.ringer-racing.com/produc...categoryId=223

Nice, I’ve never seen them listed with the option for size so I wasn’t sure if they had identical specs. I’m pretty confident that those are the same as the ones I linked to and that they have the same specs as the 48mm ones. I’ll pick up a set to see

Thanks

No problem! Didn't even notice the link in your other post. The ones you linked are 60mm 550cc EV14 injectors. Ones I linked are 630cc EV14 injectors, with the option of 48mm or 60mm o-ring to o-ring length. If you still ran your 550cc file, I'm pretty sure the 60mm length 550cc injectors would have worked just fine.

[frogspit]

Alright I got my RMA for the siemens and a fresh set of 60mm ev14’s on the way. I found some new ones on ebay for $160 w/ adapters

Thanks for all the help

Ebay sells a lot of fake stuff. China got damn good at copying fakes. Just be sure they are authentic.

[EuroxS4]

Normally its best to used AEB intake manifold and rail and convert to a fuel system with a return line.Save alot of headaches.Im sure there is other ways around it.But yeah thats the easiest way.AMB injectors and AEB are very different.


Also when In doubt just order 1050X injectors from Injector dynamics for AEB.You wount regret it!!
