Installing Front Facing Plenum Soon

i have JUST finished installing my plenum. i just need the throttle cable shortened and im done.

some things that are still fresh in my mind:

- as soon as you get it, take it to a machinist to flatten ALL surfaces on it. it gave me peace of mind doing mine and i know its plumbed up perfectly with the head.

- buy some 2.75" silicon hoses and bends (stock size) as well as some super clamps. comes in handy when cutting up pipes to fit the new cooler rout.

- test fit the BOLTS into the holes of the plenum and check if there is enough clearance for a socket to fit and tighten the bolts all the way in, i had 1 of them get really tight, it was a pain in the ass to cover everything up and start grinding while it was installed on the car.

- if you want to re-use your gasket for whatever reason - make sure its not distorted. if it is it wont let your bolts through and meet with the head. take the gasket and fit it to the plenum while its off and bend it so that its straight and meets with the bolts with no distortion.

what i did to make my install easyer was fit a few longer bolts into the head first so i could slide the plenum in and out so i could guide some bolts through the gasket and into the head. i put 2 long bolts in (one on each end) and i put the other bolts on lightly so that they had JUST started on the threads then when i had most of them through the gasket and in the head i tightend them up and replace the long bolts with proper sized ones.

what happens is you put your gasket in, it sits on the 2 studs already there and the middle bends down so when you stick your bolts in afterwards the gasket gets in the way.

- top radiator hose: just flip it around and it will fit straight on.

- get some decent small clamps for things like your fuel system (dont use the ones they give you).

- just before fitting my plenum i put all the plugs that go into the bottom in first by holding it up near the plug. its a P.I.T.A. doing it while the plenum is already on, especially when the black/blue plug has a hose that runs RIGHT next to it.

- get some decent tools, i used all of my socket sets (1/4, 3/8 and 1/2 inch). also get some ramps or car stands. ramps are #1 in my book.

- when you get your AAC valve fitting welded to your cooler pipe, get them to tap or weld a vacuum hose fitting to the turbo side so youve got a nipple on that side of the engine bay for a boost controller.

be patient, always think of your next step before you start something, start early in the day and have some beer and smokes handy and a shitload of band aids.

p.s. i have a china greddy copy on mine and i had it sanded down and powder coated by Chris from Craved Coatings and he told/showed me it had a shitload of bog in it which he replaced with some kind of alloy weld - so be warned. if you dont get it treated you risk it cracking and come off in the future which may cause air leaks.

      Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.

      The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.

      Ethanol Content Sensor - Always at 11%?

      Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
