Hi there,
Currently have a build Sr20det in my s14 and the only thing that wasnt upgraded was the vct, the vct ended up being super rattly so I replaced it with one that wasent, 2 weeks later the new one started rattling, if I was to swap my vct cam gear with an aftermarket cam gear would I need to retune the car?
Thanks
