So I was looking at this car today and noticed all kinds of worthless evap crap behind the motor. Is there a write up on eliminating all the unnecessary evap/vacuume/ sensors in my engine bay? My car doesn't have ac but does have PS. Thanks for the help. I've never owned a 4cyl Honda before!!

 

You're gonna want to keep that "crap" for the PCV system.

 

Charcoal canister interacts with the pcv on a Honda?

 

That helps keeps a lot of the fuel smell out, and keeps crankcase pressure down.

Find other things to remove like any cruise control modules,or anything like that.

 

why not just keep the engine bay clean and well maintained?
it can look good while having all the "crap"

 

Also depends on your local laws. In my area of the country my build only needs to pass safety, so I can delete everything and anything I want.

Once you start deleting evap and rerouting this or that, it can get really complicated to try to revert back to stock if you ever need/want to.

 

Yea like mentioned above if you ever need to revert back to stock its a head ach sometimes and fumes from fuel might be smelled but if your just looking to remove something you dont use such as power stearing or AC or cruise control then go for it but i dont think its smart to remove something thats part of the engines pcv sysem/ emissins equipment unless your converting to a catch can ect ect. Espessially on a daily driver.

Engines can still look clean with all that crap like raverx3m mentioned haha Heres a pic of my old GSR after the engine was detailed, Maybe clean it up a bit and it will be more appealing to the eye haha.

 

Yes that's the motor that's in mine, it has that dual runner intake manifold. It has a Kevlar or carbon fiber air inlet and spark plug cover though. It also has a stainless header I was just wanting to make it easier to move around in the engine bay. And also eliminate chances for vac leaks etc

 

you starting to remove items at random will actually cause more vacuum leaks than prevent. Just maintain the car and keep all hoses and plastics cleaned and maintained.

My wife's EM1 engine bay. Pretty much has everything in it as well. Just cleaned and maintained.

 

This is my engine bay currently minus the silly booze bottle for an overflow. And it's been degreased and pressure washed a few times

 

Don't look to bad, Use some simple green and a tooth brush and scrub the valve cover it should come out clean.

Id use some spray on wax and hit the engine bay and wipe it down for a waxed and shinier look.

 

FYI, the purpose of the evap system/carbon canister is to recycle the fuel vapors from the tank back into the intake to be burned (after its stored in the carbon canister and vented through the tank vent valve). As temperature changes, the fuel tank pressure changes. Since carbon is excellent at absorbing fumes/gasses/odors its the choice for a "storage medium". That's why you see carbon AC/pollen/cabin filters.
If you have emissions testing where you live, leave it be.

The PCV system is designed to vent the crankcase under high pressure conditions (wot) and recycle them back into the intake by flushing the crankcase with fresh air. Follow the PCV system tuning and it will all make sense.

A few things you might want to look into...
Relocate the battery and fuse box. Braided clutch line. Wire tuck the engine harness.
Swap to a single runner manifold and ditch some vacuum lines. (or ITBs if you got the cheese)

This really cleans up the bay IMO.

 

They both eventually go to the intake and get burned. But they are 2 separate systems. Nothing allowed to escape to atmosphere and pollute the air.

 

Worth repeating.

 

I'm very auto experienced. I've been working on cars for over 20 years. The comment about the intake manifold is a good idea. That dual runner one looks over complicated. I looked around and saw a nice one by golden eagle that looked nice. Is there a write up anywhere about what vac lines are needed and what can go? Thanks for all the help

 

Ok cool. So I won't have to explain all that technical stuff again. Sometimes we just assume that everyone is young and new to cars in general and we have to hold their hand and explain why you cant do certain things lol. My bad ☺.

None I know off hand but I think you'll have to keep the electric vent valve connected or else it will throw a CEL.
The vacuum lines should be self explanatory. I'll see if my manual is around.Vacuum is introduced to the dashpot with a compuer controlled electric valve which opens the secondary runners.
I forget but does the GSR have an egr system?

The skunk2 manifolds are the hot ticket right now I think.

 

The running joke is we're gonna take the 1000hp 69 camaro to the local hangout to ask the " pimply faced kids" what to do with our Hondas lol. As for vacuume lines I'm sure I need MAP, FPR and power brakes. Over that not too much?

 

Hahaha yeah I feel like an idiot when I have a General Motors question.
Yep that's about it..
