Bar.
My manual says my 86Q should be reading about 1 bar when idling. It idles at about .4 bar. Also the highest I've ever seen it go is 1.1 bar. I take it that it should go higher? Will changing the O2 sensor and cleaning the ISV improve the boost?
I mentioned the other day that I was looking for a V8 Quattro from the early 1990s. Would I be making a better decision in going with an S4? Not as much horsepower but quicker. Any other pros and cons that jump out at you.

Go for the S4
From what I gathered, the V8 is a great car, if you're willing to pay for it. It doesn't get great gas mileage, and parts are expensive.
The S4 (or 1991 200 quattro) are much better, if you're happy with a 5-cylinder turbo. The 91 200 quattro is an S4, with the previous chassis (the type 44, found on 5000, 100, and 200 from 84-91). The S4 (which replaces the 200 quattro in 1992) has more improvements, and costs quite a bit more.
In short, I think you should go for the S4. The V8 is great, but the S4 is better.

Re: Bar.
For the 86tq:
Engine off, key on, the reading should be 1.0 at sea level.
Idle 0.4 sounds ok.
It should show 1.3 or 1.4 bar.
Go here: http://www.sjmautotechnik.com
and start the diagnosis as to why you don't get max boost.
My guess: full throttle/idle switch should be replaced.
On the v8 or s4/6 front: v8 is automatic, except for around 50 '91 models and about 5 '90 models. S4/6 is 5-speed stick.

Re: Bar.
Thanks CJ, as I said above, the SJM site was fantastic. Followed the instructions at SJM and re-soldered my Throttle Switch. Now when I turn the key to the "on" position it reads 0.9 bar. It's still idling at 0.4 bar but I did squeeze out an extra 0.1 bar to top me off at 1.2 bar. Close enough eh? My idling went way up to 2000 rpms so I cleaned out the ISV and am now idling around 1200 rpms which is where I like it.

The hollow (non-sport) front sway bar which fits the S4: Is that from a FWD A4 or Quattro? TIA guys.
