Safari Snorkel Install 1st Gen 4Runner

[LaOutbackTrail]

Ok guys, I though I may post this up because I really had a hard time finding any information on installing the safari snorkel to my first generation (1987) 4Runner.

I'm no mechanic, I'm not very imaginative, I may have done something wrong, and I may have used the wrong bits to do it... So only use this thread to give you ideas!

Basically, you start off by moving the igniter coil out of the way and taking the air box assembly out.

You must also take the plastic inner fender out of the fenderwell and you need to move the wiring loom under there as well.

Then you tape your template onto the body.

Drill some little holes

Then a big hole. Tape off the area to keep from screwing your fender up even more!

I had to take my grinder to the hole larger at the top for the snorkel to properly fit. Meaning the hole is more egg shaped. Drill the hole to the inside as well.

Then you need to put the studs into the snorkel, I just used my fingers to get them as tight as possible. I also put Loctite to them.

A test fit

If it works, you then take the little bracket and find where it goes on the A-Pillar. I marked 4 little dots for reference, then pulled the snorkel off again to be able to mark 3 more holes to drill. Do yourself a favor and pilot drill them with a small bit... I started with the correct size bit and it ended up slipping and hit the windshield, chipping it a bit...

The bracket has 3 plastic bits that are hammered into the pillar and the bracket is screwed to that. Snorkel is then bolted to bracket.

Once everything is bolted down, you've got to start under the hood.

The under hood took a bit of thinking. I thought about flexible exhaust but it wasn't flexy enough. Then I tried to go to salvage yards to find hoses to be able to retrofit the whole cocktail together... but none of the hoses were the right size... Then I decided to go to Lowes and get some ABS pipe. Bingo.

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!

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.

That looks awsome, nice work !

 

[liljlandon]

Now I just need to have the money to afford one

 

[Toyota Kijang]

Very nice !

Congratulation sir now you have a head-turner rig. If you were single you can use this snorkel equipped 4Runner of yours to pick up girls

I am sure it will work.

Snorkels always look nice on Toyotas but look so ugly on heep.

Don't forget to raise your axle breathers if you're planning to do water crossing.

Looks great!

On my 4BTJ80, I had one on- once a lady asked me if it was a snow blower (this was in in Austin too). I had a good laugh.

Get ready for all sorts of questions from un-educated people. I had a snorkle in my FJ62 and I got them all.

"What's that thing for?"

"Is that a periscope?"

"Do you ever use that?"

"How deep have you had that truck under water?"

"Is that a ram-air intake?"

etc...

Great job BTW, nice truck too. I'm gonna print the pics and file, I may have a snorkle some day. Where did you get yours?

 

[LaOutbackTrail]

Thanks for all the comments and compliments, guys.

I've already turned some heads, no questions yet.... except an old teacher of mine replied on facebook,

Awesome! I want to see it in action. Do you have a pretty good seal on the doors?

Not an uneducated question or comment I guess... he is a Land Rover guy....

I bought the snorkel through 4wheelparts.com, but I'd recommend, and regret not ordering through some local guys TRDParts4U.com I think they're forum sponsors here too...

I havent raised the axle breathers yet nor have I put the computer into the glove box.... both are on my lists of things to do. But, tomorrow I'm going to tackle a roof rack.

I'd keep an eye on the corner nearest the exhaust... I'm not sure how much heat the ABS will tolerate.. Very nice job, and very nice write up!!! Thank you!!!

I'm off to FAQ this!

What size pipe is that? Looks like about 2".

Was your original intake on that side of the airbox, where you attached the PVC? Mine is a little tube that exits the airbox in the front, sucks air from behind the headlight.

Its 2" and it all worked great! The original air intake came from next to the headlight and to the left side of the airbox, not in the front.

I have written before that Australia didn't get the 22R in that vintage Hilux and 4Runner, the Safari Snorkel was designed for the 2L and 4Y. The only piece you would of needed to remove from the original airbox connctors was the plastic piece that directs air from behind the headlight along the left guard and bends downward and then towards the middle of the car, which directly connects to the metal air box tubing, that linesup exactly where the short silicone hose connects to the snorkel, like where you have it situated.

 

[LaOutbackTrail]

Correct, Safari Snorkels' design wasnt based on he 22R platform.

There was a magazine write up that I found where the guys had the same problem. So, What they did was find a bit of intake tubing and came up with this...

And they then routed the hose like this...

But in my case, in the top picture, the hose on the left (the one that connects to the airbox) was chewed up by something and was unusable.

I am been trying to figure out how to adapt a snorkel to my weber on my 22R.

I seen some Air cleaners on ebay once that fit weber..... that was suppose to hook up to a snorkle............now I cannot find them.

I have had many questions but my favorite question so far about my snorkel (and there have been more then one of this same question) is "Is that your exhaust??" (I belly laugh every time I think of it)

I now answer them (with a straight face) saying "yes.. I placed it right next to my window so I can smell the exhaust fumes and know it's still running"

I know. I'm an a'hole huh?? lol

Weber Snorkle Kit - JTOutfitters

Iffy vendor, but so far im happy with them. They ship faster than marlin, but lack the customer support ive come to love about marlin.

I thought I'd tack something on this older post as it still comes up in searches and is pretty thorough. Just finished installing mine so it's fresh on my mind. First, the template provided is a little off. The main hole in the fender should be centered about 1/8" up and to the rear when looking at the fender (ie: 2:00). That's why everyone has to trim the hole further after drilling. The inner fender hole (on the engine bay side) needs to follow the outer fender hole. The 3 stud holes also need to move 1/8", but straight back, not up. That's a starting point. On my truck, 1/4" would have been even better.
Next is the intake size. Since these snorkels are for low revving diesels, they're sized too small for higher revving gas engines. The throttle body on a 22RE is about 2.5", the inlet on the air box is 2.5", but the necked down portion of the snorkel where it enters the engine bay is about 2 inches, 20% smaller. At low RPM that's not a big deal, but no need introducing restriction into what is already an exceptionally long intake path. Good news is the larger part of the snorkel before the step is right at 3" OD, an there's plenty of room to clamp a hose if you cut off the 2" step down part. You will have to clamp it from within the fender well, plenty of room though. From there you can either run a 2.5" or 3" hose to your air box. After some searching I'm using flexible brake duct hose which is available in 2.5" and 3.0" ID's. This is what's used on track cars to duct cool air to brakes. It's high temp, reinforced, waterproof and light. This will require you to fit a 2.5" or 3" elbow to the lower air box to attach to. If you run 2.5" you'll need a step-down adapter (3" id to 2.5" od at the snorkel body). The reason I keep noting 2 sizes is that fitting a 3" elbow into the lower air filter housing runs you into the air filter where 2.5" does not. I'm still looking at mine deciding which to use.
