has anyone deleted or re-routed some of the wiring systems that are at the side of the plenum and around it?
I'm ignorant to wiring stuff, but i would love to move everything i can away from the plenum for ease of access and just a cleaner looking bay.

Post pic's, how-to's, theories and whatnot that you have.
Please.

If you remove the EGR, AIV and boost solenoids you can remove the whole harness bundle on the passenger side.

My boost controller stepper motor is there now, but otherwise that side of the plenum could be blank.

The water hose bypass helps a bunch too.

Not on the plenum, but you can relocate the PTU to under the nose panel, it cleans things up a bit too.

I assume thats a vibration dampner on your engine(balance tube)? did you make that yourself?

I did the avi delete. I'm taking the plenum off tomorrow so ill try to get the EGR off again, its a pain in the a** to get to, especially since i have gigantic hands...
Also the ptu has been relocated as well.
Keep em comming guys.
Any thoughts on deleting the fpr on the plenum?

I like this thread giving me good ideas when I pull my motor in a month or so keep it going (anton i am taking notes :chuckle: )... As for the fpr (fuel pressure regulator) I dont think you want to "delete" that maybe just relocate it.

Stillen engine damper, custom powdercoated.

Do not delete or relocate the FPR, IMHO, just paint it if you feel the need to bling.

Getting the EGR out with the engine in the car is a whore, good luck with that. Getting it out of the bottom of the plenum is easy though, with a flex head 10mm socket.

might try to relocate the fpr over to by were the FF is...

your talking about where the pipes go into the plenum?
that ones easy enough. I might try to get to the egr from under the car.
The battery cables over there are a pain as well.....
Any of you relocate the battery to the trunk? if so, did you leave something under the hood so you could be jumped from the stock location? get what I mean?

IMHO, there's no point. The FPR is hidden enough that it's mostly out of sight. The Dampener is more visible, but neither is an eye sore. Unless you're running AN fittings and braided lines, I wouldn't run long stretches of FI hose over the engine bay.

Just read that in another thread as well.
Ive done the fuel line re-route, which cleard some space all in itself.

So, now on to the drivers side where there are a massive amount of hoses and wires all shoved into a small space right up against the back, right side, of the plenum.
what do we have for that. Especiall the hose with the gawd-awefull S-bend in it. I think its a coolant hose IIRC. anyone re-route the fusebox?

I'd undo that reroute ASAP. It's a waste and foolish to run fuel hose for lengths that long. There is nothing wrong with running the OEM fuel hardline, and no benefit to rerouting it. The only need to reroute fuel lines is with a 300° rail or a BTW/Winfactory top feed system.

Image

The S-bend hoses are for the clutch and brake boosters. Also note on my other picture the cruise control has been deleted for a cleaner look.

I eliminated the PRVR system, hence the silver U vacuum hose on the hardpipe.

You can relocated the fuse box on the driver side fender for a cleaner look, but many of those vacuum connections are required for essential systems.

from fuel filter and return to fpr and ....(?) drawing a blank, on the plenum?
I'm running stainless line.
Ive deleted most of the deletable stuff from Robos writeups.
but Ive seen a memebers engine bay, and it was Immaculate. Most of the stuff around the plenum was gone, rerouted, or tucked.

That S bend looks like a hose could be run straight down and then connected to the clutch and break boosters.
Must give you props on your engine bay. That s*** is CLEAN.

Thanks, lots of work went into it :dblthumb:

Mike, member Z32TT-R has a very nice engine bay, lots of re-routes.

As for the brake booster hose, there is a check valve up top which must be incorporated.

Ill have to look for him on here. There are some engine bays that I've seen that were almost ocd looking when it comes to re-routes and stuff. but they looked like a painting of intercourse(lol).
Im stripping the purple off my plenum and PC'ing it black. all the bolts and little stuff will be purple, timing cover will be modded and cam gears will be purple. not too much purple but in all the right places.

As "boring" as it may be, I'd leave the timing covers in tact. Sand and smooth and paint them if you like, but opening them up or leaving them off is foolish, IMHO.

so that whole bundle where your helper motor is, was just egr stuff?

I've heard the horror stories.
Someone over on 300z made custom covers they cover top and some of the sides. I just want one to where i can take if off without removing the hardpipe,and not so many hex screws. Thinking about going to a simpler plenum as well, Might just be pipe dreams. Gotta get her running first.

Stepper motor/solenoid for the HKS EVC boost controller. There is usually a bracket on that side for harnesses and vacuum lines which I deleted.

Unless you have adjustable timing gears, which require extensive dyno tuning to set properly, there's no need to remove the timing covers more frequently than every 60K miles :biggrin: The fan blows air directly on the front of the engine, and can/does shoot debris at it as well. You don't want a pebble getting between your TB and a cam gear.

If you're wanting to have a clean plenum, do all the deletes you can and sand the plenum smooth. Once smooth, paint it or have it powder coated. Thats the best way to go IMO. A lot of work, but worth it.

Thats the bracket Im talking about. So I can delete it....good,more space.

By "clean plenum" I don't mean as in regards to looks. I mean:

I want to re-route the EFI harness so it's not visible, re-route some of the hoses so they are in better locations. I have big hands, so its s*** trying to get to some stuff in/on the engine. By big hands I mean about the size of a polar bears paw......

Im looking now for info on deleting the IAA unit. No luck yet.

Thanks Tony, although you prob be against my fuel line reroute lol, either way I ditched about 7-8 fuel clmaps doing it, less leaks ;)

You can delete the clutch booster, just use a check valve like the one in your booster line, that will help clear alot up on the driver side, also my FPR is routed under my mastercylinder along with the fuel filter. And fuel dampner is routed against the firewall. Next thing thats getting rerouted is my powersteering reservoir.

You know how easy it is to just take off my DP's? too easy.. lmao. Wait till the plenum and some other things are welded shut/rerouted, then Ill be more satisfied.

All that work and some motherfcuker steals your hood, BASTARDS!!! :tisk:

Yeah, I definitely don't agree with the fuel line re-route. Especially when you can get constant tension spring clamps for the fuel lines to prevent any possible leaks.

My only concerns with the FPR and FF being under the MC is the heat from your DPs.

But yes, your engine bay is very minimalistic, nekkid :biggrin:

Are you Z32TT-R on 3ZC?

EFI is still there, just pushed out the way alil. Everything is only a couple mins to get too, but its not like you should have issues all the time with those hidden parts. But it also made more room to work with other things, so it depends.

Damn thieves!! :chuckle: . They're not exactly close to the dp really at all, plus the rubber fuel lines that originally are that close coming from the hardline survive there for so long out the factory, so Im not worried. Yes Z32tt-R
