Hey guys! Follow along here as I slowly build out our 2025 Mudbath TRD Pro 6G4R. Can’t wait to get started.

Purchased on: 9/16/2025

First mod we did was the OTT tune. You can read about my experience here: https://www.4runner6g.com/forum/thr...ship-parking-lot-and-why-id-do-it-again.7019/

Finally got our wheels in last night! Now we have to decide…. 33’s or 35’s!?

Any update on tire selection for the 4R?

Any update on tire selection for the 4R?

Honestly no, I've been building out my Tacoma. I'm still sitting on the wheels. The 4R is my wifes daily, so it's not really a hue priority to throw 35's on there at this point haha.

I will put an upgraded turbo & an intercooler while it's essentially stock and have some fun with it in that sense before tires more than likely.

Would post once you upgrade the 4Runner with that new turbo and intercooler?

Build update!

Got the upgraded turbo from Big Dawgs Toyota Tuning installed today. YouTube video will be dropping soon.

We still need to get it on the dyno, so I don’t have exact numbers to share just yet. I will say, it’s WAY better than before. Especially that it’s paired with the OTT tune.

Required mods for this setup: intercooler and tune. Intercooler will be coming within the next couple days. I decided to go with Mishimoto.

A downpipe can always be added later, but I’d definitely recommend picking one up from OTT.
