Wondering if anybody could confirm for me that the flange on the q45 style throttlebody is the same as that of an xf throttlebody. I've got a Greddy copy intake plenum that is apparently made to bolt the q45 onto, so I'm thinking for the setup I've got in mind (250kw atw) the xf would be a much cheaper alternative.

there's an extra "gotcha" when using some versions of the xf throttle body

do a search. the tps sensor voltage is backwards as the butterfly opens backwards (its in the pfc faq in my sig too)

complete different patterns.

xf is 66.5mm stud to stud and approx 94mm diagonally

q45 is 78mm stud to stud and approx 111mm diagonally

just chop the q45 plate off and run the standard throttle body, there should be no problems with it for 250rwkw.

      There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.

      I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.

      Yeah - I mean, go the other way. Smaller range. Not larger.

      Duncan's V37.......race car?

      To re-cap, I bought: https://www.alibaba.com/product-detail/Lsailt-8G-Infiniti-Q50-Q60-2014_1601171829627.html?spm=a2756.trade-list-buyer.0.0.2cd476e9FTIlKE As you can see, if I bought 20 it was $653, but I bought 1 so it was $1,170. I was very tempted to buy 2 and resell 1 at 25% cheaper. @MBS206, I am not sure if they do a Kluger one, here is their list but it might be there under a global model name: http://www.lsailt.com/product/android-interface?page=1 Keep in mind these full android replacements have basically all the bits a phone does (cpu, ram, storage, wifi, bluetooth, usb interfaces) other than a screen (it uses a host), thus the $800+ cost. Android Auto screen mirroring is MUCH cheaper as it's just a cut down shell, input mirroring and output mirroring BTW I also need that "screen off" feature, it is much harder to see wildlife even if a dash is reasonably dark. Both the Fuga and V37 have display off buttons for night use, they just come back on for a second or 3 if you interact with it, eg skip a song.

      I use FCC car launcher. It has an option for different backgrounds, so instead of turning the screen off you can swipe 'up' to a black screen with no background/icons. (mine has the time on it only). It's kinda nice. Also lets you use gestures to say swipe to go to next song, etc.
