Switching From Stock To Adjustable Cam Gears, Anything Else Need To Be Done Other Than The Swap?

[Moodles2]

I want to switch out the stock cam gears out of my R32 GTR with adjustable cam gears (to save on labour, while letting my chosen garage do the cam gear adjustment later), will I need to check the timing or will it be a direct swap?

As with anything involving timing you should be vary careful. The adjustable units should have a setting to mimic the stock position. Set them at that point and mark the belt and gear position with a very clear and easily readable marker. When you install the adjustable cam gears make sure nothing moves during the process or it will put the timing out. It's important that nothing rotates during the process or you will have to work out your TDC and start again.

If you're confident and take your time and pay attention it should not be an issue. If you're unsure of your skills then best to get the mechanic to do it. In the absolute worst case scenario, incorrect timing will result in pistons meeting valves, in the best case, nothing will happen and you'll save a few bucks depending on what your mechanic wants to charge for fitting.
