Well while the z was in the back garage I pulled the exhaust off . I had tried something that I won’t do again but I used a square port gasket ( Nissan ) on my mn47 head with my square port header . I was getting some small leaks when I pressurized the exhaust during leak checks . I went back with the gasket to match the head which worked fine before .
Also stared at the ITBS for a long time trying to figure out why #3 was sucking more air . As you can see in the pics the linkage was digging into the side of the ITB . Shining a light into the ports before hand did seem to show 3 open a hair more . It was such a small difference I can’t swear I did anything , but I’m betting it’s enough . I ended up just filing the tab on the linkage down .
I also figured a way to run my coolant bypass on #6 . I’ll run it under my ITBS on top of the heat shield . Might also try again to run air for a remote IAC . It’s actually getting too busy under the ITBS .
Also on the to do list is to find some different cooling fans . I want to run brushless for the versatility and power since I want to install AC . AC is ordered from AC solutions but that’s a month out at least .
Cold air box got glued tonight . 75mm Stacks are getting printed out and I’m getting close to finalizing this long project !
