JDM4X4's 1987 Toyota 4Runner SR5 Build
So I just bought an '87 4runner 2 weeks ago and it's completely stock...for now. I use to have an '85 Pickup with a 5 inch lift on 34's and a weber carb, but I didn't build any of it I bought it like that. I'm really looking forward to this build it'll be the first time I've done this much work to a truck. I'll get pictures and a rough plan up as soon as I can.

It was like .5 grams per mile over the limit for NOX. I changed the spark plugs and wires after the first time, then if failed again. Now I have adjusted the timing, replaced the air filter, fuel filter and a couple of the vacuum lines. It is running a lot better now, I just haven't had time to get it tested again (I'm going on Tuesday). I also ran a compression test just to make sure i wasn't crazy uneven, it's a little low but it's pretty even.

How is the cat?
Triple check vacuum lines using fsm. I failed multiple times before figjring out my lines were messed up on egr system. Also check egr to ensure it is clean.
Good luck

Welded...yikes.
When I failed twice, I had replaced:
- Cat
- plugs
- cap/rotor
- wires
- cleaned air filter
- timing adjust
- cleaned EGR
- Replaces O2 sensor
After all that I was still failing. Looked at the FSM diagram for vacuum hoses and noticed I had hooked some up wrong when I last adjusted something - fixed and passed with flying colors.
Also, just check for vacuum leaks - you could have a leaky vacuum hose. spray wd40 around the hoses (gently) while idling...if idle rises when you do, that hose likely has a leak.

I'm planning on replacing the exhaust anyway. Thanks Phil I totally forgot about the wd40 trick. By the way where else can I find the FSM, I tried the link from the thread with all of them and it didn't work.

Try right clicking and saving this file - that's how I got mine (this is for an 88 but should be fine for you):

If that doesn't work, go to the source and right click on the same link:

Here's a photo I would have taken more today but things got a little crazy.
Goals for the near future:
Pass emissions (#1 priority, it's getting tested tomorrow)
Stop as much of the leaking as possible
Adjust valves
Replace exhaust/intake
Replace front coil springs, leaf springs and shocks
Tires
Clean the body up a little bit
And any other little things she throws at me
Long Term
build motor for supercharger on the side (10lbs)
re-gear diffs to 4.56
bumpers and sliders
rear disc brake conversion
Rims and tires possibly with spacers to get a wider stance.
soft top
interior (more details later)
marine grade sound system
transmission/t-case?
finishing touches on body (i.e. little to no rust, minimal dents/scratches and mostly
even paint)
it's gonna take some time, and money, and it will probably change at least 3 times, but that is the plan for now.
