As far as I know the late US VR6s got a plastic inlet manifold with variable geometry, much like the R32s and 24Vs. Now, this should be retrofittable to the older VRs, I assume they just need an adaptor for the throttle body, and a little bit of piping making up?

Was fiddling with both Fay's and my VR today, and while looking at the measuring blocks, I noticed that my idle adaption was above 1, somewhere near 1.18, but Fay's was below 1, about 0.95 or something.

Now I know that 1 is stoich, i.e. AFR 14.7:1, so, an adaption value of above 1 indicates that the car is running rich, and below 1 it's running lean.

I.e. above 1, it may have an air leak after the MAF?
