I have an au3 70mm t/b to go on an el xr8 & was wondering do I need an egr spacer? I can get a 70mm edelbrock egr spacer for a good price so that isn't a problem but the au doesn't use them so will I still need it or does it just get blocked off?

EDXR8

The AU TB already has the spacer built in to it, but no EGR ports on it because as you already said the AU's dont run the EGR system. You could use the Edelbrock spacer as well which will mean the TB sits out a bit further and then you can run the EGR system. If you don't use it and disconnect the EGR syste you can run into problems with pinging and your EEC will throw up the EGR error code every time you test it.

So in order to get around this and use an AU TB with EGR stuff, i'd need to modify the AU spacer to use my current EGR stuff?

How much are the Edelbrock spacers? I have a spare e-series egr spacer that I may consider parting with.

EDXR8

The 70mm AU 220kw TB has the spacer built in and no provision for EGR to be used unless you use a second spacer. The 65mm AU TB's just need a matching EGR spacer, you may be able to use the AU one and drill out the EGR holes but I would just use an aftermarket one.

Would there be any problems using an aftermarket spacer with the 70mm t/b?

EDXR8

It will just sit a bit further over because the TB has a spacer built into it already.

Has anyone found a way to trick the ECU to thinking there is egr gear on there? Because it makes more sense to just rip off the old TB and egr spacer, and put on an AU spacer plate and 65mm TB..

You can trick the EEC by leaving the EGR electronics pluged in and just block the vacuum line and EGR ports. The main problem still is the light throttle pinging which the EGR helps to stop. The aftermarket spacers are not that expensive and will save you all the problems.
