Hey guys,

Been a member here for quite some time, have owned multiple 4Runners and Tacoma's! I have settled on this one as I got it for a good price!

So, I finally decided to start my own build thread... I will cover my 4Runner and my Expedition Trailer in this thread.

My 4Runner right now is very mild except for my turbo set up, and my trailer is still in the beginning stages of its transformation, but has come a long way!

4RUNNER BUILD:

I picked it up last spring, 97 SR5 manual, 4x4, 169k, completely stock. It has been neglected a bit, and had some grinding into 1st and 2nd, so I did some powertrain maintenance with some of that Redline magic! I changed every fluid in the truck minus coolant (it had been done recently).

Mods:
Custom Rear Mount Turbo (pretty much the same as Clownmeats)
2" body lift (to accommodate for the turbo charge pipe).
Scanguage II
Boost Gauge
Oil Pressure Gauge
Plastidipped stock wheels
Bunch of misc. maintenance things.

Turbo set up pics:












Essentially my whole setup


TRAILER BUILD:
Here are the goals for my trailer:
1. Budget Build!
2. Simple as possible
3. Rugged, durable, easy to work on
4. Functional

So far I am less than $250 into my build. I have been very fortunate and lucky at time to pick up many of my items for free and/or very cheap!

Trailer: I got it for free from my dad. It was in pretty rough shape, but a great starting point!



I got an extra piece of T1-11 plywood from my family cabin that I am going to use as the bottom board for the trailer

Replaced the main center beam... it was completely rotted out! I also traded a small air compressor for a new axle, and was able to salvage the same leaf springs from the old axle.


I completely lucked out and picked up a set of limited tundra/sequoia wheels for FREE! I will be running these wheels on my trailer and my 3rd gen 4Runner.


Started building my vertical supports and corners. (Dont mind the mannequin in the background... its for my business!


Test fitting bottom plywood, cooler, and 2x6's



Exterior 2x6's initial fitment and measurements



Tailgate, Kitchenette framing, and 2x6's bolted


I hated the look of the round tubing as my "vertical posts" on the sides of the trailer, so I cut them off went with some flat bar instead!


As of yesterday (2/2/16), I have tied everything together on the main frame, finished the tailgate latches, capped the top, and bought my 23/32 sheet of plywood for my lid (not pictured).
Sitting next to my 4Runner... makes my runner look tiny! Guess its time to install that 3" lift that's been sitting in my garage for 3 months, and pick up some 33's!




I still have a shit ton to do, but it should be "functional" as a box very soon! I need to build my multi link hitch system, build some fenders, install my lights, and mount my lid to make it usable.
I have really big plans for this trailer that will "eventually" include:
3-4 man RTT on pop up frame (like BoxRocket's) to allow access to lid
Full kitchenette with running water, and Ecotemp L5 heater
Electrical system including 12V/110 power, large inverter, LED lighting, Solar Power charging capabilites
On board air compressor
Rear tire swing out carrier
Fender "extensions" all around to hold propane, jerry cans, water cans etc,
Lot's more that I know I'm forgetting right now.

Let me know what you think, thanks for taking a look!

so my question, the air intake on the turbo, what stops it from sucking water up?
The intake is tucked tight against the bottom of the body and surprisingly avoids excessive water spray from the tires. Most people will get a breathable "sock" the covers the filter, or you can cover it with panty hose as a cheaper option. I'm embarrassed to say I do not have anything covering mine, and I live in Utah but have had zero options!

I'm guessing you are never going off roading and going through mud puddles or fording any water?

I forgot to elaborate on that... I will be installing a snorkel soon and routing my intake through that with an inline filter! I have every intention of getting this thing wet this summer while pulling my trailer around :)
 
Do you have any videos of the truck running? Also what are your plans for tuning? I'm really considering selling my supercharger that I have and doing a setup like yours.

As far as tuning goes... I am running completely off the stock ECU. I am only pushing about 4 psi at the moment. From what I have heard is that if you want to push much more than 5, then you need to have a piggyback or standalone. I copied "clownmeats" build (below). There is a ton of information in there about his build.

Turbo setup is looking clean!! I like it. Can't wait to see the snorkel incorporated, as my first thought was how much water/mud/stuff would get in there offroading.

Also you should post a video of the BOV. I'm curious how it sounds
 
Looks great man!

Sounds like you already have plans with the inline air filter. If you need any insight feel free to PM me. I worked with Spectre Performance/K&N to create a custom setup with inline filter for my snorkel and ran tests including CFM for future applications. It's pretty straightforward but happy to help if you're looking for it.

Thanks man! Here are a few videos... the first one is earlier this summer driving through Ogden Canyon here in Northern Utah. The next 2 are videos I took today on the way home from work.

2. City/Freeway entrance (about 40-50 throttle because people were in front of me.

3. Light acceleration on the freeway

Clean turbo install! The only thing keeping me from doing the same is I haven't been able to figure a way to do a snorkel that I like. I'll be watching your progress!

[MENTION=8329]MillerPKA[/MENTION], Thanks man! I might hit you up soon for some general ideas and education on the inline filter build! I am trying to get it finished before Easter! Heading down to Moab with the family for the 50th Anniversary celebration...

[MENTION=105046]sandracer33[/MENTION], thanks for the compliments! I am planning on getting the Hilux Surf snorkel and running some flexible pipe back to the turbo inlet!
 
Update

Been doing a lot of work over the last 2 weeks...

Threw on a roof rack.

Then the lift and tundra wheels.

Then rear leather seats (don't mind my messy interior).

Then the rear storage compartment.
