Rock sliders if it actually goes offroad.
This is correct. My 4Runner did not pass the smog visual inspection even with the deckplate inserted as it was considered an "air cleaner box modification" and is not allowed. I have an intact factory box I picked up at a junkyard which I use to swap in to pass smog. It is worth the money though to do it. I've picked up +9HP from the deckplate, +9HP from an oiled filter, and +43HP from ditching it all and building a custom 3" intake. +61 HP from freeing up intake restrictions alone.
Alphyn does your 4Runner need a tune? I know enough about tuning to be dangerous and can help dial it in. Can't remember if you have a wideband sensor or not, if not that's what I recommend starting with. The 7th injector gives enough fuel for a pulley as small as the 2.1" pulley so I would take larger injectors off your list, unless you plan on removing the 7th injector entirely?
While your 4Runner is under the knife, take a spark plug out and measure the spark gap. Those gaps are sneaky and really open up over time on a supercharged engine. Anything over 0.035" and you'll start to lose power.

OT, but because I've BTDT, unless you're buying brand new and don't mind weeks/months of possible downtime, skip the Sprinter. They are a nightmare from every angle ~ like I said, Been There, and Done That. I'm in the Transit now, but that's because I'm unwilling to do a Fiat (Dodge), when Dodge has a history of changing business agreements and abandoning vehicles (first gen Sprinters).
My Transit is now 3 years in without a single unplanned trip to the dealer/shop. Maintenance only.
For the actual topic, any fluid not replaced in the past 2 years is due. Brakes, steering, different gear oils, coolant, whatever. If it's fluid and hasn't been done in the past 24 months, do it. Next would be looking at the brake lines (flexible), cheap as hell and beats the alternative of a brake failure. Beyond that, replacing the control arm bushings made the single biggest difference in the quality of ride on my '99. WAY more difference than the Bils 6112/5160 combo or any change in tire on any vehicle.
Briefly, if you regularly use the 4Runner as a necessary vehicle for the next 5-10 years, I would focus on all those items you think a daily driver needs in order to last a long time.

For a somewhat frivolous, pure sex-appeal (OK functional, too) upgrade, I think a set of BXBuilt trick AF retrofit headlights is about $600. Not on my own radar, but they are as popular as a big swollen lips are for Beverly Hills housewives.
Just something that I didn't see on your lists at first glance.....

Edit - Lead Time not good - ouch. Like I said, "Popular"!
This one won’t break the budget - get rid of that squeaky clutch spring.
Use a big flat screwdriver to pop that old one out and toss it. Put in a linear spring. It’ll take 10 minutes and cost from free up to a couple dollars.
Mine has been done for years and no regrets.
Finally someone else who can empathize with my pain! I've seen a few different fixes for it. Adding brackets, changing out springs, etc. I've owned manuals my entire life and it seems like a ridiculous oversight by Toyota not engineering a better solution. More of a rant than anything else. Nice to see someone else here who likes to row their own canoe.
i ripped mine out as well and put in a small coil spring. i got one pack from HD, and that turned out to be too firm, so i went to napa and got one that wasn't so heavy-duty and it works much better.
The spring gets strummed a bit like opening an old screen door, but oh well. it's far better than the alarming clatter and poor return.
Any chance you remember what length spring worked the best?
I'm going to call out a great analogy when I see it. I can imagine perfectly how it would sound. Memories of my grandparents house in Montana came roaring back. Thanks for taking me back in time a bit and putting a smile on my face.
in terms of length, the spring i ended up with is about 3-1/2" long and about 3/8" coil diameter. i wish i had the PN but i do recall they had a couple available as kind of off-the-shelf all-purpose springs, and this one had the lower rating (as in pounds to pull). the ones i got from home despot were 40 lb, and that is way too much.
Perfect! Again, I remember reading through posts before talking about grabbing random springs and shovin' up in there only to have to try a couple before it worked out. I think that's how babies are made, not sure. Anyway, this is the first time I recall anyone providing more constructive advice than trial and error. Really appreciate it! I'm on a roll solving long tolerated 4Runner probs. Without you and the rest of the folks here, I'd be in a tough spot. Thanks again!
Annnnnnnnd after I get this sorted I am going to tackle deferred maintenance on my 300zx. Pray for my soul.
