Never had the need to do the conversion on a cos....the cos rack suffers at low speed on tight chicanes etc...we have on the past drilled out the standard rack galleries to increase flow....combined with a 90 bar pump this works ok...
I'd say it'd depend on what you were trying to acheive...weight saving?...increase in power?...IMO i'd stick an easy feel rack and a 90 bar pump on....

Need to get rid of standard pump to solve a prob. At High revs (8k+) mainly when on Nitrous it sheds its belt. Have had new pump/ belt & lazer aligned but still does it. Not a prob on the road with 7.7K limit. Just looking at all solutions, have found others that have had similar probs.
