Vortech V2 G35
Hey all.
My cars been running a V2 vortech kit since around 30,000 km (now sitting just over 105K). Recently ive been thinking about doing my timing chain, as I believe im at that mark that i should be doing it and would hate to have my timing skip as that was be catastrophic. Im pretty knowledgeable in mechanics and usually do everything myself, but something about messing with my timing and changing my timing chain myself in a one car garage on a jack stands seems pretty sketchy. Should i take this thing to a shop, full send it myself, or drive it tell she skips timing and blows up? Also would i need a re-tune after?

105,000 kilometers is only 65,000 miles. These timing chains aren't a maintenance item and are designed to last the life of the vehicle, personally I wouldn't go replacing it unless you are actually having problems with it. The primary tensioner however would be ok to replace and that can be done through an access window in the timing cover.
If you've ever done a timing chain before then you can definitely do the one on the VQ engines. It's just got more parts to align it's not actually HARDER.
Set TDC and impact wrench the crank pulley off, remove the valve covers, cam actuators (don't let the actuators point face down or the exhaust-side magnets fall out and you'll be buying new ones), and timing cover, remove the tensioner, primary chain, secondary tensioners, secondary chains. Might as well replace the water pump while you're in there. Replace sprockets and use the pictures in the FSM to set the secondary chain alignment pins with the colored notch on the secondary chains, set secondary tensioners. Set the primary chain colored notch, install primary tensioner.
Once everything is set I usually turn it by hand two complete rotations and verify everything is still aligned, then install timing cover, valve covers, crank pulley. The hardest part is torquing the crank pulley bolt on a 5AT vehicle, the flywheel lock tool is expensive and I never found a suitable budget replacement so RIP $200.
