      Shaving the Engine Bay

      not doing a full shave just yet (probably should have during the build) but i want to clean it up as much as i can get to now.

      AC is already ripped out, vacuum brake boost pump is gone, ripped out the stock cloth firewall and am installing that gold heat shield stuff, and am removing all the stock crap wire looms to do everything up in heat shrink wrap stuff.
      its gonna be a pita but if i can remove most the unused wires, cut the wiring harness thickness down by half, and tuck as much as possible, it will be one sweet looking engine bay.

      my question is what else can i dump?

      what about this ~1/2" vacuum line with some sort of valve that goes from pre turbo intake to the intake manifold then has a thin hard plastic line running somewhere for fuel? what exactly does that do?

      what about the PCV system? i am also installing a catch can and would like to just vent to atmosphere and avoid the whole pre turbo heating element and stuff, but what is the part of it that connects under the intake manifold - to the breather box - to the coolant housing on the head? whats the point of that?

      ill be posting pics in my build thread along the way and thanks for the help!!

      That brake pump serves an important purpose. And the car will be angry with it gone.

      really? because i read a lot of people unplugged theirs when they go bad instead of replacing them and never noticed a difference. it is just there to assist the brake booster when the engine is cold and doesnt have full vacuum.

      Under certain (vacuum) situations, you WILL notice the lack of vacuum!!! (big time, like no brakes)

      Creating a hill under boost and hitting the brakes you'll notice.

      LOL, I'm not sure what wires in that loom are optional since its every one is required for a running engine.

      Just clean up what you got, there is nothing 'extra' in there for you to get rid of.

      Also, that extra line you speak of is for the EVAP system. Check the check valves to make sure they are still working since when both fail they will create boost and vacuum leaks. Don't get rid of it unless you always want a check engine light for a EVAP system failure.

      Tony if you take the wire harness off for the injectors it'll really clean up your cam cover.

      The OTE pipe is also unsightly and can be removed.

      ill deal with the CEL later. if i cant run it hidden i will remove the evap can and vent the gas tank to atmosphere.

      the wiring harness is FULL of wire that arent needed. think about how many different cars this wire harness was used for across the world. i know of at least 5 visible plugs that are in the engine bay not doing sh*t. plus just by stripping the plastic loom off and doing a shrink tubing wrap will save a TON of room and make it look SO much cleaner.

      i dont think you guys understand the look i am going for

      And every one of those cars is identical... Volvo's ME7 harness was used on 5 cylinder ME7 cars... Which are all identical... Only plugs that wouldn't be connected are lighting related.

      it will be less brakes, but not NO brakes.

      cars have been running fine without evap and vacuum boost systems for decades. ill be just fine

      wiring for the AC, this vacuum pump, lighting, power steering (once i remove that), the 4C system, etc.
      there are PLENTY of wires i can remove lol

      Uhhhhhh you really don't want to drive an R without power steering. Seriously. Ever. It's not fun, it doesn't get easier with speed.

      So you think that power wire for the A/C is really bulking up that harness? Dude, you are going off the deep on a fools errand. What is there to see about the evap system, it lives UNDER the intake manifold so unless you have x-ray vision I don't see why this is a problem for your sense of aesthetic.

      Think about the fact that you have 15 wires for the coils, 10 for the injectors, 6 for the cam sensors, 4 for the CVVT solenoids, 3 for the crank sensor, 4 for the knock sensors, over 10 for the O2 sensors and a giant power cable going to the starter and alternator. Add a few more for the evap solenoid and oil pressure sensor and that's the bulk of what's running around your engine compartment.

      So which of those do you plan on ditching for some crazy idea?

      The bulk of all this runs along the subframe where no one can see it so why is this such an issue?

      If I was running cams then I could see keeping the vacuum pump. But other than that the Car really doesn't need it.

      Oh there have been times that pump is helpful. If you shove the clutch in on boost and slam on the brakes you'll want that pump.

      As for the power steering it's almost impossible to turn the wheel without it.

      I think you're on the wrong forum for this sort of thing...

      I think you're missing the point of shaving an engine bay. The point isn't to eliminate "unnecessary" components (like AC or power steering), but to cleverly route them in a neat, organized fashion. This is a difficult vehicle to achieve that with. You should maybe consider why some people haven't done this yet. Just because it's different doesn't make it a good idea.

      Do what you like, but if you ask a forum for answers, especially one like this with many learned people, don't disregard information provided with snarky remarks.

      To me it is unecessary. I drive this car maybe 1,000 miles a year. After this it'll be the interior and roll cage time.
      I think you are missing the point. I'm turning this R into a show car. I could give 2 fu*ks about AC and other "luxury features"

      So, now that we have that aside, y'all can stop telling me how hard the wheels will be to turn without power steering and help me with what I need to do to remove things

      Ask ScottishBrick what his ME7 harness looks like. He has a complete one from a 99 T5M. Aside from the extra CVVT solenoid and grounds being in a different location they're pretty identical. That should give you an idea of what can go.

      I still think leaving power steering would be smart. Moving 2 235+ wide tires with all the weight on them is not fun without power steering.

      I don't understand why you would sleeve the motor and put a big turbo on it if your not even gunna drive it..
      And why when you had the motor apart you didn't even clean it up that much or powder coat things like mine 😄

      I'll prob end up keeping it. See if I can't get the pump mounted where the AC compressor used to be. That would work perfectly.

      I don't understand shaving the engine bay, although I do like a neat and clean bay. I don't get ridiculous, hilarious camber. I don't get people urinating on their hoods to get that sweet rust look.

      But hey, it's your car. As long as you aren't violating your local inspections (or, like FL, have none) and aren't a safety hazard on the road, who am I to disagree?

      Even if it's phenomenally stupid. Personally I think it's a troll on the similar level to dougy's improvised hood scoop.

      ^ This. If someone asks for my input I give it, even if its that their idea sucks.

      I would never go as far as saying he shouldn't be posting this here though, to each their own after all and its their property and money to do with whatever they desire.

      People have been driving for decades without power steering in cars with steering racks designed for no power assist (no hydraulics, higher ratios, less caster). Doing it with a car/rack designed for power assist is another matter entirely.

      He should test his theory by getting up to speed on some twisties and shutting off the engine to see what its really like. It might actually cure him of this crazy idea.

      Had a boost hose pop off at 20-30mph... car stalled. Honestly didn't expect it to be that bad... But it was.

      No power steering is actually better for handling.
