Haha give me a few days, I am not as interested in CA sites since I already have an SR but I'll see what I can find or maybe you could ask that on the CA forum.
BTW Here for all the CA18DET and SR20DET owners and curious enthusiasts is the site where you can get the Factory Service Manuals in english on PDF (adobe acrobat format) for those engines. They are about 27mb each but contain about 800 pages of information in each. Very useful info for home swaps.

PS if the site ever goes down just im me for the files.
