I am still waiting for these parts to arrive. I am expecting them all in the next week or so.

SCS Gen 5 17" -38 Offset in Black
Total Chaos 3.5" Race Long Travel Kit w/ King suspension
ADV Fiberglass Fenders
C4 low pro front bumper w/ clearance cuts
Victory 4x4 strike rear bumper

The build is about to take off here mid November. The parts and pieces are all arriving about the same time. I will be producing a YouTube video for the ADV fiberglass fenders. I am looking forward to partnering up with ADV for that video... it will be fun to shoot and dispel some potential rumors about their product.

Over the last week I have added in an ARB manifold into the onboard air system and the ARB bluetooth pressure switch. The manifold serves a few purposes, it allows air to cool before entering the abs air lines to prevent melting or overheating. It also will serve as an air storage device for ARB air lockers when it comes time to do the install of air lockers. I have very limited space in my engine bay, so I opted to place the manifold on the exterior of the drive side fender well. In order to mount and protect the manifold I 3D printed a custom bracket as well as a shield to keep rocks and most road grime away from the solenoids for the pressure valve.

I finished up hammering out the pinch welds and cutting the fender mounts down to clear the 35" trail grapplers this week. I also cut the body mounts for the total chaos BMC plates. I welded the new plates in and ground it down to look smooth and clean. Shot it with some rustoleum protective black paint and I am very happy with the results.

I will add pictures in a day or two when I make it back to the shop.

I am strongly considering changing out the TRD Pro seats for something that will accommodate my comfort, as well as provide support for baja style driving. I have been researching suspension race seats. I will update later once I have made some decisions. My current plan is to do the Goosegear sleeping package to remove the rear seats, install the 2nd battery & Redarc solar setup under the goosegear platform. I am still working out the PPS (Puppy Protection System) but I am looking forward to putting together the interior.

I have a potential tuning solution. The HP Tuners route came up empty, however, UniChip has successfully tuned 2020+ 4runner models with their piggy back tuner. I am working with Tony at UniChip, he has reached out to procharger to discuss Tuning specifics for the Procharger kit and is confident he can provide a solution. I am holding out on committing to this route until it is absolutely necessary in order to get the build on the road. I would MUCH prefer to flash the factory ECU and not have to meddle with the wiring harness and rely on a piggyback tuner to trick the ECU.

TRDlun4r build is coming together... Hoping to have it on the road in December.

I love the ambition of this build. I wonder, how was removing the Pro rack? I've seen Youtubers struggle with the screws that mount it in place, stripping some.

3/8’s impact and the right size torx bit and it came off no problem. Didn’t have to heat it up or anything. I didn’t rush it, but in all seriousness it took me about 3 minutes to pull the rack. Were they using an impact or maybe a ratchet? I could see them stripping with a ratchet. Just slow and steady with an impact and it knocks them loose and pulls through the thread locker just fine.

Sucks to hear about the procharger not having a tune yet. I can tell you on my 19 the procharger was a game changer. One thing I have noticed is that the transmission has no clue what to do for shift points after the SC and bigger tires, so if you are going under the knife it might be a good time for 4.56s. I get mine on tuesday.

Yeah that’s coming, parts are going to be a challenge. It will be gears and air lockers at the same time…

i have a Urd. Whipple in mine, 4.88 gears and 34", my biggest complaint is definitely the transmission,, it does get lost at times. Hopefully its not as crazy with the procharger setups.

Do you find that is is wandering between 3th and 4th? Where does it get lost?

i actually get some hesitation off the line. doesn't seem to wander much around 3rd and 4th.

Just drove mine home from the shop with 4.56s on 33s with the procharger. It used to wander between 4th and OD, it didn't shift a single time all the way home.

Do these transmissions (Toyota A750) physically have 5 gears, or do they have 6 and only “see 5”, like the Mopar 545RFE?

When you net out your change in gear reduction (3.73 vs 4.56, right?) against your tire size change (31.6” to 33”) you still wound up with a significant increase in gear ratio!

yeah it's about 4% off on the speedo but so far I like it a lot.

How reliable would a GPS based speedometer be for highway cruising?

For example, if you found a flat, straight, stretch of interstate and calibrated their T4R speedo (in the cluster) to a GPS based unit, would that get you closer in accuracy than your current state of things at 4% off?

Did you tune for the exhaust or are you running the standard procharger flash?

I have a GPS based speedo in my dash and it regularly is connected to 14 satellites making it very very accurate. I'm not sure how to calibrate in built in toyota speedo since I think they take speed measurements off the ABS sensors.
