1987 4Runner- Expedition Build Up.

Cut some holes and let us see. Looking forward to this.

I didnt have a 3" hole saw, so I made a trip to Lowes. Will try to get it finished up in the morning. But, I need to figure out how to route the air into the airbox. May go PVC, may go to a junk yard and find some other hoses.... who knows.

I did find this install bit: http://www.4wdandsportutility.com/tech/0408_4wd_safari_snorkel_air_intake/index.html

They used a hose from a Mazda truck (center), the stock intake hose (left), and the bit from Safari (left). The problem that I have is that the intake hose on my truck is chewed up pretty bad and quite holy.

And Routed it like this....

If I cant find a hose that'll work, I'll probably go with PVC pipe.... but I'd rather the setup they have above.
 
I went to two junk yards this morning trying to find a hose to do the retrofit. Unfortunately, it seems that all of the newer vehicles, even the small 4cyl economy cars have 3" or larger air intake hoses. Hmm. So, a trip to Lowes was in order, I came out with 6ft of ABS pipe and two 90* elbows. I think It might work.:sombrero:

A female and male threaded adapters, they fit nicely into....

The original inlet to the air box.

Due to the power steering lines, I had to make another trip to Lowes to get another elbow to finish the routing.



Below are three views of the finished ABS pipe routing.

I used about 2 ft of ABS pipe, a 90* elbow and two 90* "street" elbows. The regular elbow has the two female ends to receive the pipe into them and the "street" elbows have a female end and a male end, allowing the male end to be stabbed into a female fitting.

Worked out quite nicely I think!

It appears to be the prettiest thing under there! :coffeedrink:

You are moving at lightning speed. Way to go! One of the fastest build threads I've seen!
 
And the finished product! I like! My wife came outside to admire it and said... "Now all you need is a roof rack," of course I also reminded her of the need for an ARB bumper.:sombrero:

Looks good but...be careful with the ABS pipe. It gets brittle in hot or cold temps and if it burns puts out a very toxic gas. I am sure it will work and not be an issues but keep that in mind.

Curious why you didn't use some silicone turbo pipe? And say some stainless steel fittings?

I'll keep that in mind, but I thought ABS was the better choice over regular PVC?

As far as not using something else? Product availability. I used what I knew about and what I could find. Where would I find "silicone turbo pipe?" I may change the setup later if the ABS fails.

All PVC pipe is brittle in cold or hot temps and all of it puts out a toxic gas when burned. If you want to commit suicide just smoke some PVC pipe and youw ill be dead in a hour! Obviously I am being sarcastic about the suicide part!

I hear ya on using what is available, I just used 3/4" pipe in my trucks water system. Overkil for sure but I had a bunch of 3/4" fittings around so I went for it. Doing it over I would just buy 1/2" fittings and use 1/2" pipe.


ABS pipe is for waste. It is thin wall and a non-pressure rated pipe. Ok I think for air intake. SCH40 is a high pressure pipe and is the most common type of PVC besides ABS. There is also class 100, 200, ect. rated for different pressures. All PVC pipe though is pretty much manufactured the same and all of it gets brittel in hot cold or even from lots of sun exporsure. Like I said though I think you will be ok for the air intake.


Silcone pipe is usually blue but also common in black. Here is a pitcture where you can see some small sections of it used on a diesel engine I just had built.

There is certainly better pictures out there if you do some searching to see the type of pipe I am talking about. A quick Google search turns up this for links...

Any fittings for sensors (ect) can be tapped into the steel fittings. You could use aluminum, stainless or perhaps even galvanized exhaust fittings. Your best seal would come from a fitting with a lip like your radiator has but using the really good clamps should be just fine. We have a large hose shop in the nearest "big" town close to me, 100 miles away. They have all kinds of hose and fittings and clamps and can make stuff up too. Very useful place for me in the past. It is called Evco, you might look around your area and see if there is something similar.

Would a heat sheild deflect enough heat to make a difference?

If so, it may be a worthwhile upgrade, regardless of the material, to keep the air from gaining as little heat as possible as it makes its way into the engine.
 
If you are looking for new tires and want to save some money consider these guys, http://www.treadwright.com/shopnow/...e/category/categoryid/35/sename/Specials.aspx

I have been using them on my Defender in all conditions for about 4 years with zero issues. They are easy to deal with and will ship right to your door.

Actually, today I was visiting a local salvage yard, and they just received a 95 Tacoma. It has factory rims and almost brand new 31x10.50 BFG All Terrains, one isnt that great of shape.... I think I'm going pounce on them, $45/wheel and $15/tire.

Mr. Leary, wanna help me pull them one day?:sombrero:

Good idea. I do have some insulating exhaust wrap that I was going to use on my bikes. I wonder if that'll work?
