Looking good!
From recollection, it seems to me that there is an awful lot of material on the adapter plate itself. If it were me, I think I would remove material from it rather than the TB. I don't see why you couldn't remove as much as a quarter inch and be OK. Might need to do some minor porting afterward. Also, if you are considering a phenolic spacer, adding an extra quarter inch there might also alleviate some of your fitment problem...between the two, you could gain 1/2 inch of clearance!

As for the linkage, the two bolt holes on top of the intake plenum are used on LHD cars to hold the throttle linkage. Why couldn't you just rig up some tiny little guides and route the throttle cable around two posts and pull it from that side?

pocketscience, for what reason you are using turbo intake manifold?

The turbo intake manifold runners are a bit longer than the NA's, which moves the plenum to the LHS of the car by about an inch or two. Due to the Weber TB he's using, it would interfere with the fuel rail, so the 931 intake manifold helps by providing add'l clearance.

At least I think that's the answer

Will the arm ot come off then you can turn it 180*.

My Audi TB needed the arm swappign and they appeared to be fairly standard spindles.

Thanks Peter, that helps alot - and matches some research and experimenting yesterday.

If this were destined to be a race car I'd pull the head and get it done, but for the time-being I'll simply do some minor mods to the manifold - that would have to be marginally better than leaving it as-is (completely unmatched).

Is JB Weld really suitable for that sort of application? I've never used it, but it sounds like extraordinary stuff if that's the case!

Cheers,

JB Weld is rated up to 315C (600F). Don't know what temps the intake ports get up to but I can't see them getting anywhere near that.

I'd be more worried about the jbweld breaking up and getting sucked into the motor.

Nice fuel rail, shiny.

Yeah I imagine you couldn't just slap it on - but would need to key it to give it something to hold onto.

FR courtesy of the Todd-meister - shiny indeed. Valve cover is going on a black ops mission soon.

My TB had an arm stop and a throttle stop IIRC it was just the arm stop that had to go. It was in the way and redundant when I swapped the arm over.

No pics, but probably only applies to certain models of Audi TB thinking about it....
