I give some tips and advice on the Stillen grounding kit install, since the instructions that come with the kit are terrible.
This is my 2003 Nissan 350z Touring 6 speed. It has JWT C8 cams, and was dyno tuned at Z1, making 300 whp and 284 wtq. The idle lope sounds amazing, with or without the silencer that now comes with the Z1 single exit exhaust.
My 350z's mod list: Z1 m-spec race intake, NWP throttle body, Z1 plenum spacer, JWT C8 cams w/head work, Tomei Expreme headers, Motordyne ART pipes to resonated XYZ pipe, and Z1 single exit exhaust. Also have Z1 rear diff cover, Z1 non-brembo brake package, Z1 lightweight flywheel, and Z1 mild performance clutch kit, paired to Exedy lightweight flywheel. If it's not obvious, Z1 Motorsports is my main performance parts and mod supplier. My z was dyno tuned at Z1, making 300 whp and 284 wtq. I will be retuning in the future, for some changes I've made to the intake system.
