    • The car revs up through the gears much better/faster now, and fuel consumption doesn't really seem to have be affected either on a Hwy cruise, which wasn't expected  The FAB9 intake manifold has been problematic sourcing though, I've contacted Plasmaman to ask about their intake, which you can get different runner lengths spec'd, and, their different options for throttle bodies  The only real physical drawback with the Plasmaman intake is how to connect it to my current OEM style airbox, as FAB9 make a OEM style back half of the airbox to suit the larger diameter throttle body, and all that is required is a 30°bend silicone pipe to mate the throttle body to the airbox Car also goes in for some exhaust work in a week or so to fit the biggest resonator they can fit clearance wise in the front pipe to help remove some of the drone, there isn't alot of realestate under there, a rough guesstimation is it will only be about 3-400mm long and maybe 90-100mm diameter, and with a 60mm exhaust that doesn't leave alot of space for the internal volume of the resonator to do its thing I'm thinking I may need to bin the "high flow" 100 cell cat for something a bit more substantial, yeah, and restrictive, like a 200-400 cell, to help, but, I have ample room for a really large bodied cat to replace the current one which has around a 4" diameter body I may look around in the recycling bins and see if I can find a massive newish cat that was "replaced" with some new full exhaust system that the local exhaust shop in Western Sydney is doing
    • Hahah look at that smile 😂 Just like those ones on IG where they compare the husband in family photos vs husband going fishing lol. I don't think I'll participate this time, clutch isn't in and also the last time I went there were too many numpties on the cruise sessions. Nearly caused a few accidents holding up people and a few guys initiating massive kerb to kerb drifts with heaps of cars right behind them. Not to mention, there were guys on the track session using it as a power cruise session.
    • Is there an actual website thingie for peoples who don't have Facebooks? Cheers
    • All Jap Day is coming up again! 13th of July this year. Are you going? Tickets go on sale on Wednesday 6pm. Please let Quang know as well. https://m.facebook.com/photo.php?fbid=1163155775853542   I still get shit from my wife for this photo because it is the happiest she has ever seen me. And it's not with her, it's in someone else's car.   Quang's EVO is sick, but that rotary wagon flying past was absolutely bonkers.
