Recently installed Z1 hfcs, Z1 z-tube w/jwt pop charger, and Z1 5/16 plenum spacer.

The previous owner also put on a flo-pro muffler (not sure why) w/ a magnaflow midpipe.

Here's a sound clip. Btw any suggestions on coilovers for the g35x? It's an 06'

If you want to drop it on the cheap, 350 springs and struts give a 1" drop and an OEM ride. As far as coilovers, stay away from the cheapie offbrand eBay stuff and you should be fine.

 

If you get the 350Z springs just make sure they're the revised ones. Nissan uses color coded dots on the spring to identify them, there's a thread somewhere around about which ones are the revised.

 

Gotchya, forgot to mention I have an X, and I heard that dropping on springs on an X is hard on the AWD components, but I was leaning towards Truhart or Megan Racing coils. Will look more into getting Z struts and springs tho, thanks for your ops

 

Double check the intake/MAF with the AC line and make sure it's not touching or rubbing. Common issue with the ztube/popcharger

 

gotchya, will do
