I think he's gonna be doing them in batches of 10 folks as long as there is interest.

Just post on the GB thread that you're in over on TW and he'll add you then PM you payment info when it fills up.

That is not possible. To change the RPM at a given speed, you have to change gears in the drivetrain (transmission or differential).

Not going to argue, just gave my impressions. My truck drives way better is all I know.

Read the whole thread and talked to a friend that knows a thing or two about racing, he says it's makes sense and can work nice with a few adjustments on the stock ecu. So I can say I jumped on the group buy. 
Might be interesting with the ecu reflash i've been postponing.
BTW. I'm interested in low end power, not racing:car:

The taco guys use HP Tuners. It's about $500 for the tuner and credits. I was told by the resident tuner on TW to reach out to HP to see if they have the parameters for the 4R transmission as apparently it differs from the Taco. Don't have the scratch quite yet so I haven't gotten around to it. But you should, and report back......

Luckily I have a friend that has been getting good results on ecu reflash alone on several brand cars, obviously having a stand alone tuner like an HP or Ucom will work alot better but that's a bit out my budget for the moment.
Invested too much time over the weekend lurking around the taco forums.... Kinda hate that place now.

i'm a sucker for bolt ons that actually work.

Damn, I don't get how they improve anything if they're the same radius and such. Any good threads on TW about it? Never heard about these until now. Might be nice to just pretty up my engine bay.

It’s the weight reduction in the lightweight pulleys basically reducing resistance. Plus that red anodized aluminum would probably look sharp.
Btw. Thank you for starting this thread. Been watching it for weeks since the group buy #2 was ongoing. I just got in for the group buy #3. This seems pretty intimidating to me, but then again so has everything else I’ve done on my 4Runner so far.
Thanks to this great site with tons of experience, it’s a lot easier to have the confidence to get this kind of stuff done.

It's seriously not that hard at all. Just take your time, plan for three to four hours. Stay organized, lots of bolts come out. The valve cover bolts that go around the covers are finicky. They're like 8 lbs torque value. Be careful I snapped one. I was using a milwaukee M12 3/8 ratchet, accidentally squeezed the trigger past the lowest setting and boom. I'd do them by hand for sure. The mercedes engine mount tool was perfect for torquing the gear bolts.
If i could go back, I'd budget more time and paint the valve covers while they're off. I'll probably do that eventually anyway.
I would do the blue, my plenum spacer is blue. I bookmarked them for later......
The timing is what scared me the most. I turned the engine to the 0 mark on the crank pulley probably three or four times until the cam gear timing marks lined up. Once it was all perfectly lined up, I was careful to not move anything anymore. The gears are a bit tricky to get in, but not impossible. Just be patient.

I installed both at the same time so kind of hard to gauge what improvements each gave. My truck drives loads better now though. Better skinny pedal feel, lower idle, even the exhaust note changed. Definitely worth the time to do it.

Finally have some mpg data to report. I always fill up until the pump stops, and calculate the mileage by writing down the mileage at fill up and mileage at half tank (10 gallons).
Here is the last few before the gears and the ones since. The first one had a bottle of Lucas injector cleaner. The last one included an easy Sunday drive on the highway to a local waterfall picnic spot loaded up with cooler, disc cooker, propane tank, two kids and wife. Not bad for the price of the gears!

Dang, thats a solid 2mpg upgrade! Would be interesting to see how much improvement there would be on a stock 4runner, which makes me tempted to hop on the buy. Where I am right now, speeds are all over the place 25-65mph, so I've gotten as low as 14mpg on a completely stock 4runner.

Before my Falkens/Ray 10's I had heavier wheels and Nitro Trail Grapplers (MT's). I had no plate bumper, skids, sliders or hitch carrier with full size spare and she was doing in the 13's around town, it was atrocious lol

Heck yeah, that’s awesome! Did you also do your spark plugs too or anything else with the gears at the time?
My should arrive tomorrow. It sure when I’ll get around to it. Still have to get everything else that goes with it.

I did install a manifold spacer at the same time and new spark plugs and PCV valve.
