I have bought an imported b16b and took the cover off to install skunk2 cam gears and a new timing belt. When I was in there I noticed that the springs and retainers all appear to be titanium. This got me thinking. Surely no-one would go to the trouble of replacing them without replacing the cams too? Now what I'm wondering is, is there any easy way of identifying what cams are in there? I guess, at the end of the road, it won't make a lot of difference when it comes to tuning it because it'll still be a case of dialling them in but it will make a difference if I ever want to skim the head or increase compression. Or want to sell sometime in the future. Thanks for reading.
