zman240uk 0 Posted February 28, 2006 I'm pretty new to the VR6 tuning game and I have just purchase a set of 268 cams. When I have had hot cams in other cars I've needed adjustable cam pulleys and some careful timing to get the most from the cam. Does the same stand for the VR or do they just fit as a direct replacement with the timing being unaltered from standard. Also, as I am about to do the cams I figured I may as well do the timing chain also. How difficult a job is this and can I do it with the engine in situ? Cheers...

Kevin Bacon 5 Posted February 28, 2006 There aren't any vernier pulleys for the VR6, so just stick the cams in and off you go. You can't change the chains without dropping the gearbox unfortunately. Quote Share this post Link to post Share on other sites
vdubjb 0 Posted February 28, 2006 Cat cams makes a set, but you need to pull the inlet mani off and everything to get to them. It's only useful if you have cams that are poorly machined and cant get them timed properly. http://forums.vwvortex.com/zerothread?id=1264409 timing chain install faq.

VRTrickster 0 Posted February 28, 2006 Im not entirely sure but I was thinking of fitting these cams as well, but was unsure because I think it is advised to use shorter valve springs? Quote Share this post Link to post Share on other sites
vdubjb 0 Posted February 28, 2006 Catcams? You can go up to 272° with no issues other than lumpy idle and horrendous low end response. I have their 268°'s with the thinner mkiv headgasket and have had no pinking, or valve/piston clearance issues. Sounds like bare malarchy. lol Quote Share this post Link to post Share on other sites
