I ordered a few things a few weeks ago which I'm not going to install just yet so I want to pass them on while they are still practically shop new. first up is a Prosport EVO style wideband o2 gauge with bosch sensor. http://prosportgauges.com/wideband-air-fuel-ratio-kit-EVO-Red-Blue.aspx Asking $280 inc delivery aus wide through aus post. next up is 2 Greddy Knock off BOV's (you can set them up as plumb back with an additional fitting not included in the kits) pic... asking $50 each including postage aus wide. $90 for both. all items are brand new and still in box. I will probably have additional items for sale soon including HDi Electronic Boost controller $100 + post (minus t pieces) oil pressure gauge $50 oil temp gauge $50 (oil pressure gauge was once wired into the Z but the gauge itself never connected).
