BFAD, said I had to do a Build thread...So I'm finally starting this almost 11 years after buying my Runner.
I bought my Runner in August of 2002 at a Big Tent Sale at the Fair Grounds. I was looking for a Pre-Runner for my wife and I looked at the 4-Runners they had and wanted a white one since I had a white 93 4-Runner for the last 9 years.
I didn't see any white ones and didn't want a dark colored Runner. I was also old School and wanted chrome bumpers and not the painted plastic which gets sand blasted out here.
As we were walking back to the big tent to work out a deal on the wife's Truck I spotted this Gold Runner sitting out front. So, I asked the Salesman to see if it was available...
It was so I checked it out and bought it too. We went home with a new 2002 Pre-Runner and 4-Runner that afternoon...
In August, 2002, I found YotaTech and the Mods began.....
In October 2002, I replaced the stock suspension with 1"Performance Product Coils and Bilstein Shocks. I got about 2" lift with that combination and that really improved handling and the ride over that mushy stock suspension.
Then in 12/2002 I took the plunge and did both the Silencer and Elbow removal Mods on my 2002 Runner.
I did the Elbow removal first because taking out the air filter box made the Silencer removal easier.
I did something different for the Elbow removal. Instead of just removing it I got a little creative with my Dremel tool. I wanted to avoid having to remove the wheel well components to take out the remaining part which is a major pain in the arse.
So, here is how I avoided this:
I drilled a pilot hole and cut it out with my Dremel.
This is the end result.... A nice big hole where the 90 degree bend is
So, now I just reassembled the modified elbow. No rattles, no hassle with the fender well cover and the Dealer will never see the Mod.
And lastly I placed my pipe in place of the Silencer and spliced the hoses with the brass "T" purchased from NAPA.
I did remove the EFI fuse for 15 minutes. On my 2002 4-Runner it is a yellow 20 AMP fuse.
End results are GREAT!!!!!
Even with the OEM paper air filter there is a noticeable difference in acceleration And combined with my Dynomax muffler it sounds awesome.
Thanks for the help and the Links to Bob's write-up on the Elbow removal.
For the
ISR Mod I was one of Dr. Zhivago's "guinea pigs" since I had a 2002.
I have my write up on YotaTech still, Bob, moved them when they overhauled the Forum some years back:
Intake Silencer Removal Mod Update for 2002 4Runners
Intake Silencer Removal Mod Update for 2002 4Runners - YotaTech Forums
1/2/2003
Paul (ALBPM on the forums) shows you how he did the Dr. Z intake mod, and had to do a few things differently on the 2002 engine.
Here's the Revised Mod for a 2002 4x4 4-Runner as the engine differs from the 2001 and earlier models. Notice the lack of a hose port on the plenum below for the 2002 engine.
Step 1:
This is the FPR hose that was attached to the Air Silencer Box - Now removed and replaced with a Steel Pipe. It won't be needed so remove it.
Step 2:
Locate the "Capped Off" Steel tube coming out of the rear of the plenum. Remove the cap. You will also see a length of unused steel tube on the top of the plenum.
Step 3:
Locate the round FPR unit behind the plenum. Remove the piece of vacuum tubing that connects it to the steel pipe running under the plenum to the front. You have already removed the larger hose from the front end of this steel tube in Step 1.
Step 4:
Now you are ready to add the new Vacuum Hose to connect the unused line coming out of the rear of the plenum to the FPR unit. I bought 2 ft of NAPA part # H-459 it cost a whole $1.25
You will need ~3.25" to connect the capped end to the steel tube. (right side in picture)
Step 5:
You will need ~11" to connect this end of the steel tube to the FPR unit.
Now, pull the EFI fuse out for a few minutes and you are done...
Total cost for the 2002 and possibly 2001 Mod done this way was $6.25 total.
$5.00 for the pipe that replaced the Silencer Box and $1.25 for 2 ft of the NAPA vacuum hose (part # H-459).
Here is the mod in place on Paul's engine.
Made me feel good to see my version of the ISR Mod on 4-Ripcords 2002 Runner the first time I checked his out in 2011....
