Not very exciting but done..double crimped wires, heat shrink covering and then some spare split loom since I didn't use coated wire. They are stainless but we'll see how long they hold up. I suppose I should knock the surface rust off the clips that hold the table closed...maybe later ...

Changed the Drive belts tonight. S/C belt was in bad bad shape and had been slipping...not to hard to figure out why!

Hardest part of the job was getting to the power steering tensioner bolt...PITA

Out with the Old..
S/C belt was toast!

A/C belt was worn and cracking

Power steering belt was in pretty good shape


In with the New!

What started out a simple supercharger pulley upgrade (downsizing pulley 2.2” to 2.1”) turned into a nose cone swap. The old pulley and nut were seized. Strap wrench and ½” ratchet didn’t work to break the nut free. Tried a number of things (even tried an impact…although this is not recommended) but ended up clamping a vice grip on the front of the pulley and using a 3 foot breaker bar with a silly amount of torque and PB blaster to eventually knock it free. The pulley well that wasn’t going to happen. Put the puller on it and all I did was bend the aluminum pulley. Quickly aborted this and pulled out a new nose cone kit I have been sitting on for a few years. Easily slipped the 2.1” pulley after coating everything in antiseize. Next, had to trim the plastic cover on the front of the motor back a bit more to expose the bottom bolts for the nose cone. Used a syringe and straw to suck out as much oil as I could…maybe 10cc at most and it looked/smelled pretty bad. Shoved a bunch of towels under the nose, unbolted it, tapped the tabs a couple times with a mallet/pry bar and off came the cone. I was shocked at how little oil came out….it definitely need replaced and refilled. I doubt there was much more than 10-15cc left in the cone…supposed to 120cc!

Let this be a lesson to all you boosted 4Runners out there….keep up with your S/C maintenance…oil changes are necessary!!

Installed the new nose cone…easy peasy, put the belt back on and holy smokes….way way way quieter. Quick test drive….boost comes on much faster. I didn’t peg it so no idea how much boost I gained. Will take it slow for now and see if I need to reprogram the piggyback computer and/or consider water/meth injection. In the end…guess it was a good thing the old pulley seized and I had a spare available. FWIW, still trying to get the old pulley off…PB Blaster, torch…still not budging…will keep trying as it would be nice to rebuild this cone and keep it ready for future use.


Seized/bent pulley


Bad supercharger oil (should be clear and should be A LOT MORE OF IT)


Nose cone removed….looks pretty good to me


New nose cone kit ready to go!


New and shiny nose cone/2.1” pulley


PITA!

Done!

Added a oil catch can...figured why not since I am now running more boost with a smaller pulley. It’s not like my engine is getting any younger...maybe reduce some risk? I don’t really know for sure... The one I ordered was marketed for a Tundra and came with a convenient mounting bracket.

Went with Moroso 85651

Hey man. I was curious as to what you thought about the 2.2" pulley. Could you tell a significant difference between the stock pulley and the 2.2" pulley? Or is that why you changed to the 2.1" pulley?

I have the stock pulley, and just bought a 2.2" pulley, but haven't installed it yet. That is why I was wondering.

Thanks.

Short answer, Yes, I noticed a difference and thought it was worth it.

Long answer, I ran the stock pulley for over >100K miles with no other fuel mods and was quite happy with it. In fact, that was about the only mod I had made for over 10 years. When the rear bearings in the supercharger starting to go, I made a decision to start building the 4Runner to where it is today. I pulled the supercharger off, sent it to Magnuson for a full rebuild, added the URD 7th injector kit, 2.2" URD pulley and did a bunch of other maitenance at the same time. When it was finally back together, I did notice quite a difference with the 2.2" pulley. The 4Runner pulled harder and the extra boost was there but it really ran so so much better overall after the tune-up it is hard to give all the credit to the pulley upgrade.

The reason for the recent upgrade to the 2.1" pulley was nothing more than curiosity and greed. Since I originally added the 2.2" I have added a lot of weight and larger tires and was feeling a little sluggish. Re-gearing definitely helped but I wanted to see if a pulley downsize could help even more. With the 2.1", boost comes on noticeably quicker than the 2.2" and it again makes me smile when I step on it. I rareley drive around at max boost and don't really know that the reported 2.5-3.5 extra PSI the comes from upgrading from the stock pulley to 2.1" actually moves my heavy truck around that much faster but the throttle response is there and the whine of the supercharger is very satisfying as is the seat-of-the-pants feel. No regrets...I would do it again in a heart beat.

Thanks so much for the detailed response! Very informative. I will be installing the 7th injector kit at the same time as the 2.2" pulley also. I'm hoping to see a very noticeable difference over what I have now.

Did you have to do much tuning when you installed the 7th injector?

You’re welcome. This build had been an evolution, very few short answers.
I have performed “zero” tuning...everything runs fine. I am pretty sure I could get more performance with some additional tuning but it hasn’t been a priority. I am sure I will get ther eventually...

Needed more spaces for some switches so followed @infamousRNR lead and added 4 vertical switches to the bottom left of the radio bezel. I bought the switch holder and some abs plastic on amazon, some JB Weld Plastic Epoxy putty at Oreilly’s, had some sandpaper and flat black spray paint. It ended up good enough for me but could have been smoother with coat of bondo and some further sanding. Everything went pretty smooth…had to notch out the shifter bezel to fit around the new switch holder but otherwise pretty straight forward.

Another good trip to Croom Wildlife Management Area…with @SHagood . Brought my wife and kids on this trip and they loved it!

Looks tits dude! Good job.

Awesome build! Curious to know what you have in mind for fishing rod storage. Avid fly fisherman here.

Thanks! As far as rod storage most of my spinning rods fit inside and I strap them to the grab handles on the passenger side. Not elegant but works for me. However, if I was going to be transporting rods frequently (especially expensive fly rods) my first thought would be to place the rod pieces in a rod sock then slide them into an appropriate sized pvc pipe, add some end caps and mount to my roof rack. This has been done by many and I think there are some off the shelf versions of this design. Hope this helps!

Very nice!
