Like I said, CA16DE cams are no better than the CA18DE cams. If you guys are going off true specs, the CA18DE cam provides .0010 more lift than the CA16DE's (CA16 1.5940- CA181.5950). Now as for the CA18DET, both cams are good for upgrades, but will affect your top end performance because of the relatively short duration. N/A users can use either the CA16DE or CA18DE camshafts and the CA18DET owners should stop being cheap (budget boosting) and either get the cams reground or get a performance set of cams if they want big performance. Once again, the CA16DE and the CA18DE cams are not that much different from each other in the fact that the CA18DE provides .0010in more lift than the CA16DE camshafts. Hope this settles this CA16DE/CA18DE camshafts and how do I know this is because I've owned all 3 engines and I've also measured all journals diameters and lobes. The CA18DE is the better motor between the two in terms of using parts for the CA18DET.

All parts are interchangeable in the head between both motors. The CA16DE's head may have a smaller combustion area than the CA18's because of the difference in bores, so you may not be able to use the complete head off the CA16DE on the CA18DE's block.

I doubt it in this case, but I could be wrong. They both have 10.5:1 compression and both have the same stroke. But they differ in bore size and because of the shape of the piston, they could very well differ in the combustion chamber area, hence the reason why there are 2 different headgaskets for the CA18 & CA16. My headgasket for CA18DET is made for an 84mm bore as opposed to the CA18's 83mm. And besides that, you don't want to jack the compression of a CA18DE or a CA16DE up unless you have the fuel management to control it.

what is 'regrinding cams', anyway? I mean, I know what a cam is (of course) and I know how putting in cams from a different engine can change performance, but what does regrinding them do?

Basically, a shop welds some material onto the cam lobes to make them larger then "regrinds" them to a different lift and duration.

Heh, you just answered a question I'd had for a long time - how you could regrind a stock cam to a larger size. The part about welding material onto the lobes first was the secret ingredient I didn't know about.
