    you should be amble to get shrick cams still from the US.

    i have heard the 2.8 MAF will go in there, but you would be looking for the later 471A maf which is a 3" housing and not the earlier 471 (pre 93) which is in a 2.5 housing, oh and remove the screen from it as well. Also bore up the throttle body as the primary aperture is fairly narrow.

    A NOS kit is not far off £700. there is a guy on audifans with a 7a in an 80 quattro, lightened heavily modified currently running NOS after a P&P job, enlarged breathing, suspension brakes etc which has already outrun some serious machinery.

    There used to be loads available for this lump, less around as its an older block but.. http://www.20v.org/upgrade.htm

    also don't over look the manifold, can never remember bu ti think its the lat ones came with a tubular manifold which is good for another 10bhp on its own, i believe to balance out the power once the CATs were introduced.
