Another thing to consider is how the stock intake is routed. The stock elbow comes from the throttle body and passes over the upper radiator hose that`s giving off heat, and connects to a plastic intake pipe that runs a long the top of the radiator that`s also giving off heat, and then connects to the factory air box that`s not far from the exhaust manifold. So by swapping the AFM and battery your taking away most of the heat that was soaking into the factory intake system. So it may not be a true cold air set up, but the air is definatly cooler than it was with the stock set up.

irab, were all of the wires long enough to reach the new AFM location after you seperated that one plug from the wire loom and retaped everything ?.

yes indeed. i was uber psyched when i found out that i didn't need to do 16-ish splices

myyota

Right on, i hope i get that lucky when i get ready to do my 86 4Runner. I need to order some stuff from www.siliconeintakes.com before i can get started.

there was a lot of dried-up electrical tape to remove before i could even start. the most useful tool i used was by far my victorinox swiss tool. i used the knife to cut off most of the tape, the various screwdrivers to gently pry the plastic inserts, and the scissors to cut the new tape. oh, and the pliers helped a bunch, too

myyota

Im sure after 24 years of use i will run into lots of dried up electrical tape and brittle wire loom. Im going to have new wire loom and electrical tape on hand when i do this so i can replace what ever i run into that`s bad.

first freeway drive this morning. going up hills at 65-ish seemed easier

100 miles down, and no issues. i did flip the afm to be right-side-up, no problems

for a minute, i thought i had messed something up. i went to check if i had thrown any codes, and sure enough, the light started blinkin' a pattern. throttle position sensor. so i reset the ecu, which did the trick. i forgot i pulled the plug off to test-fit the elbows

myyota

Let us know if you see any gains in gas mileage.

yep. i actually just filled up yesterday, so i'll have a number by friday

edit:
here is the 45 degree elbow installed. still waiting on a silicon-intake order, and the afm is right side up now.

Pretty sure you won't unless it's different than my '87. On ours the AFM wiring goes out the fender on the driver side and through the inside of the cab. Pretty much stuck with splicing.

myyota

86 - 87 are the same, so it looks like i will have a lot of soldering to do. Its no big deal, just a lot of extra work.

Nice build, subscribed!

Definitely on my to-do list.

Skip the soldering and get permaseal crimp connectors. They conduct better than solder, and the insulation on them is heat shrink that oozes adhesive so it's 100% watertight. Much better than solder. I've been using them for several years with no issues, even splicing under the truck. No signs of failure even after many northeast winters in NY. I highly recommend them. Just stagger the splices so you don't get a huge lump of splices in one spot.

Make sure you pick up a good crimper, too. Check parts-express. They've got it all.

On a related (sortof) side note- I picked up my new motor on Sunday. I'm quite happy!

the thing about solder is that when the wires are connected, the copper strands are connected to each other, not with the solder in between. while it is true that many metals conduct better than lead/tin, the crimp connectors separate the copper strands, reducing the conductivity. and if you shrink-wrap the connections, you'll have a good clean look and be water-tight.




indeed


and an update from beyond: i got the silicon intake order yesterday, installed it this morning. and the battery is flipped with the neg side closest to the frame. cool beans.

myyota

What have you noticed as far as mileage goes ?, any gains or anything else ?.

shaeff

They're not contacting each other once you solder them though. The solder runs like liquid and coats all the copper surfaces. The amount of copper on copper contact is drastically reduced. If you get a good crimper, and good crimp connectors none of that is an issue. Not your run of the mill hardware store crimper that puts one large dent in the connector. Those are crap!

Better conductivity, amongst other things such as better mechanical isolation, stronger bonds, and much, much better repeatability, no possibility of wicking (the solder going up into the wire past the insulation) are some of the many reasons that soldering is NOT used in aircraft. A solder joint is MUCH more likely to break than a properly crimped connector. Crimps also eliminate the possibility of cold solder joints too, which are very brittle and don't conduct well.

With good crimps and good crimping tools, you'll have a much higher rate of repeatability of good connections.

For what it's worth, I used to solder EVERYTHING and never had anything fail on me. I was one of the "solder is better than crimp" people, but after reading many good articles on why and how crimping is better, I've switched and never looked back. Crimping is easier, more secure, conducts better, and takes a whole lot less time to do properly.

I'm not trying to change your mind, or make you change over, just giving you another side. Do some reading on the two of them and draw your own conclusions. I know I'll be crimping anything I can.

Here is a good, inexpensive crimping tool that works very well:
http://www.parts-express.com/pe/show...number=360-642

If you crimp insulated and non insulated terminals/connectors, then get the green handled one with two different dies.

And Express Seal butt connectors are great for any wiring job:
http://www.parts-express.com/pe/show...number=095-912

Of course, get the sizes you need. When using that crimp tool with one of these connectors all sealed up, it's a wicked tight and waterproof connection that's mechanically isolated from vibration and won't loosen up on you. I love those things!

Excellent!

it would be interesting to test the conductivity of each type of connection. i might have to do that some day...

as for mileage, nothing drastic. i'm filling up tomorrow, so i'll get you all some numbers. the time i really notice the swap is after driving for a while, it's still got power up hills and at cruising speeds. it's niiiiice....

oh, and pics later tonight
more later

we interrupt your regularly scheduled programing to bring you this important news bulletin:

a sad entry in the ol' gas mileage log book. 19.6 as opposed to my usual 21-ish

but it looks frickin' awesome!!!

The fact that you lost a little mileage isn`t bad compared to the performance you gained, right ?.
