DIRTCO's 1986 4Runner Build-Up Thread
#643
The truck is running great up the hills (for a 4 cyl auto at 9500' with 35's
). I'm running around 9 pounds of boost and the thing just cruises everywhere. I was down in Denver on Sunday and on the way home it pulled all the hills at between 65 - 70 miles per hour, the last grade right before you enter the tunnel it dropped to 60 miles per hour. I could of pushed it a little harder but I didn't see the need, the sweet spot with the OD off going up a hill is 65-67 and the flats with the OD on is around 72-75 miles per hour. I also noticed that the truck spools up a lot faster down in Denver than up here, I'm sure it would be a blast at lower elevation.

The project is starting to wind down a bit, but there has been a few details that needed to be worked out.
After the snow wheeling trip I noticed that the back window was having some issues. The driver side dropped down and would not go up. After taking the whole thing apart I found that the steel channel at the bottom of the window rusted away.

Instead of buying a new window I built a new channel out of 1/8" x 1" strap and 5/16" (I think) round rod. I didn't really get any pictures but the the 1" steel is on each side of the window and the round rod is welded to the bottom, I then welded the original tracks to the bottom of that. I used a couple sections of the stock gasket to keep the glass from touching the steel and glued it all togther with windshield urethane.

I also had to trim the front of the body a little because the tires were rubbing on it. It's a lot better than them rubbing on the firewall.


And here is a picture of the blown up trunion bearing that I replaced a while ago. You can see that most of the bearing rollers are shattered.

I took the truck out the day after that last trip to the same area, but a back trail that I know of. This was an epic trip for the 4Runner because I realized this thing kicks ass in the snow; I made it ALOT further than I thought I could have. The secret was going nice and slow and floating on top of the snow, but knowing when to give it some throttle. 
Start of the trail


Getting deeper with water, the mud under the water was deep!

Thanks, but I'm no master. It just takes alot of practice, research and a clear vision of how you want the end result to be.
