Thanks.

As far as felt power increase, I'd say I'm actually a little disappointed. There really wasn't much of noticed increase in power. Some, but not as much as I'd hoped. It does have more power in the top end, but down low it feels about the same as before. I like the sound of the exhaust, but it was probably not worth the trouble of putting it in.

To expand on that, I will likely be changing up my gear ratios in the axles. I have 4.30 gears now and I want to go to 4.88 gears. That should help me bring some power back into this heavy truck.

The wheels are Konig Countersteer Type X. They are 17x8" with -10mm offset. You can see them here: FN Wheels

I'm guessing once you re-gear, it will 'feel' like a new truck.

Thanks for the link. I really like those wheels. Were the TRD center caps an option? Or did you have to purchase those seperate?

Dang Renegade, you've been busy...hence renaming your thread...ha

I haven't been on here for awhile and you've done a ton. Looks and sounds great! I really like the bedliner paint job.

Are you happy with the (felt) power after engine / exhaust overhaul?

I'm sure its in your thread somewhere, but I missed it. What wheels are those?

Great job!

Alright, well I started looking around under the engine bay and found a bunch of vacuum lines that looked bad. I checked on my OBD scanner and looked at the fuel trim levels and the truck was running between +15 and +25% fuel. So the truck was running lean and adding that much fuel to make the O2 sensors happy.

Replaced most of the hoses and wow what a difference it makes in your truck when you replace split vacuum lines with good lines. Fuel trim is still slightly positive, so I have another small vacuum leak somewhere, but the truck is running very good and and it has quite a bit more power on the highway.

So now I'm not so sure on the regear. It definitely isn't bugging me as much for now. I'll take another long highway trip one day and see how I'm feeling about it.
 
Nice build bud! I'm glad your 4runner performs better after replacing those vacuum lines.

Because of you I retrofitted my headlights and I'm building my drawer system today.

Oh good. I'm glad to hear this.

Now what will you do with the money you were going to spend on gears? hehe
 
The new motor looks great painted! Good luck with it.

Thanks! It's been running a little better after the new hoses. I am still waiting on a PCV hose and I may have another one from behind the Fuel rail leaking at the IAC Valve. I can hear it coming from there, but can't find it.
 
New Fuel Pump

I've been experiencing what seems like a fuel cut/misfire at high RPM under load, so without doing any diagnostic work, I assumed fuel pump was the culprit. (Spoiler: It was)

So I drove around until I basically ran out of gas, even that wasn't the plan exactly. The truck stalled out a couple times in m,y neighborhood while I was driving home. I was a little nervous about pulling the pump because I read some horror stories about the hoses and people cutting them off the tank. I'm not really sure why, because it took me 2 hours to do the job alone, for the first time, and my neighbor was talking to me for a little while. He wanted to make sure I was OK. Of course without 90 degree Long reach Needle nose pliers it would have been a complete pain. So that probably helped out quite a bit.

I am thinking of adding a supercharger one day and figured if I replace the original fuel pump with a new OEM unit, it should be ok since that seems to be a major limiting factor for these trucks. I've read some of the complaints of not enough fuel when people add them to old trucks but make no mention of new fuel pump. At the same time people were adding them at low mileages/new and had no issues, or less issues. I can readdress the fuel pump later if needed, it really was that easy.

This job was super easy and I'm very happy with the results. It got a little more top end, and it pull much harder at mid throttle all the way through the RPM band.

Part numbers for those who are curious:

Pump: Denso 950-0100 This included a filter sock, even though I bought one because it said it didn't.
Seal: 77169-60010
Cushion: 23249-74610 I ordered this for some reason. I don't know why because it did not seem necessary at all. Could have just reused the old one, it was fine.
 
Great thanks, I've been wanting to get around to this. Is there a thread you used as a guide?

Not really, I just looked a couple weeks ago and remember seeing a lot of complaining about the hoses. A well-equipped person shouldn't have any issues with this. You will definitely want a set of long reach needle nose pliers, both straight and 90 degree end. I got mine from Harbor Freight for about 5 bucks each. They have been invaluable, especially the angled pliers. They work incredibly well for hose clamps.

Tools:
  • 12mm socket, 14mm socket, 8mm socket
  • Ratchet with extensions 6 and 12 inches
  • Long reach needle nose pliers, straight and angled
  • Channel-lock pliers
  • Phillips screwdriver
  • 14mm flare nut wrench (I used a regular 14mm, carefully) and 19mm wrench for fuel filter

Procedure:
  1. Forget to unhook battery (oh well...)
  2. Pop up driver rear seat, pull back carpet
  3. Unscrew the conspicuous black door with wires going through it
  4. Use a pair of channel-locks to squeeze the clip on the harness right on top of the tank.
  5. Underneath the truck now-
  6. Remove the 12mm bolts (5) for the gas tank skid plate
  7. Then I started unhooking lines.
  8. At the front of the tank, its pretty obvious, pull the soft line sections off the hard lines on the tank, I use the channel locks to twist the soft line over the hard line connection to break it free, then they just slide right off.
  9. I didn't feel like messing with the fuel line connections on the line itself so I disconnected from the back of the filter with 14mm and 19mm wrench. prepare for gasoline bath.
  10. For the vent on the top, I actually disconnected the soft vent hose section right in the middle of the tank, at the rear connection to the hard pipe that goes over the rear cross support (you'll see there are 2 sections of soft vent hose on the very top). This is where the angled pliers are key. You can reach up beside it, clamp the stupid hose clamp and rotate it to a normal angle to remove it. Again, break the hose free with channel locks and pull out of the way.
  11. Then I removed the fill hose at the back. With a long extension and the 8mm socket, loosen the hose clamp and pull the fill hose off.
  12. Now, you can remove the 14mm bolt and cotter pin on the rear strap. Have a jackstand or something underneath to support it.
  13. Lastly, you remove the 12mm bolt at the front and the tank is free.


There is the second wire from the bulkhead connection under the seat, it doesn't actually go to the gas tank but its attached to the tank with a plastic clip. Or should I say it used to be. The rest should pretty much be common sense for pump removal.

Install is pretty much reverse of removal.

I wish I had thought to take more pictures, but it's pretty self explanatory as you go. Of course, after removing and reinstalling a motor, everything is probably down hill from that point...

Good luck and let me know if you need some more info.
 
New truck

Not necessarily build thread related, but I've been so happy with the 4runner that I'm selling my old faithful F250 and bought an 06 Tundra DC. I have now decided that I messed up by not doing a 2UZ swap on my 4runner.

The truck is in good shape, but had lots of scratches which were easily buffed out. I got a great deal (so far) on the truck and probably doubled the value with 2 days of work- Buffing the truck, cleaning the headlights, and putting new suspension under it.

I'm impressed with the 2UZ and the tundra in general. I was relieved when I dived into putting some Bilstein shocks on and saw that the front suspension is identical to the 4runner, in design and function at least.
 
Nice truck. I had an 01 Tundra with the 2UZ and loved it, in fact I wish I would have kept it.
I think you will be very happy with it.

Congrats.

Fishing trip

Not really much to post build-wise as honestly I'm not sure what else I'll be doing to it at this point. I do have LCA bushings to put in, but just have not had time.

I did take it on a fishing trip this past weekend with a buddy and we had a blast, didn't catch a lot, but that is how it often goes. New motor did a lot better in the 30mph head wind, but obviously still labored. I got a few questions about the 4runner and quite a few people were checking it out down there. I still love it when I turn around while I'm walking off and when people ask about it. It makes my day.

I haven't been to the coast fishing since Hurricane Harvey hit, but have been waiting patiently to return. We found a cool spot. It's a bar and grill with a huge patio. They have a few "campsites" and have bait, food, a convenience store, and a live band playing there on weekends. It was very cool place and well known locally for enormous fish!

After some discussion on the fish, we have been trying to ID it. It is a Drum for sure, but it's either a red drum or black drum, to me it doesn't have the typical hump-back look of the black drum and the gill comes pretty far back, plus its very red for a black drum. If it is a Red, that makes this fish nearly a state record at over 40 inches and 50 pounds!

Next up will be Lower Control Arm Bushings and some new LED Turn signals for the front.

Oh and my dad finally caved to the 4Runner addiction and bought a second 4runner, although this one was much more expensive! 2018 TRD Off Road Premium, loaded. He wanted a TRD Pro, but there are none to be had in Texas apparently...
