boostedka's Turbo 3RZ Tacoma

After driving around the 2.7 for about a year and half now, like many others, I started looking into power adders. After looking at parts from bolt-ons like header and catback to superchargers, I've decided to try to put together a custom turbo kit for my truck. I've been accumulating parts and information from a few people on here as well as a few others on Customtacos. Here's a list of parts that I'm using:
Precision 5431 Turbo .63 a/r
Treadstone Log Manifold
Treadstone FMIC
Treadstone Oil line kit
Turbosmart 38mm WG
Turbosmart BOV
Osidetiger 440cc Injectors
Walbro 190LPH fuel pump
AEM AFR Gauge
Autometer Boost Gauge
Lotek Dual Gauge pod
Custom 2.5" Catback exhaust w/a Gibson SFT Superflow muffler (788500)

The Truck's current other mods:
Suspension
Icon Coilvers
Total Chaos UCA's
Icon 3 Leaf AAL
Rear Icon 2.0
Energy Suspension Steering rack bushings
Energy Suspension Body Mounts

Wheel/Tires
15x8 American Racing Teflon Mojave 3.75" BS
32x11.5 Falken Wildpeak AT3

Drive train
Toyota 4.30 Gears
Marlin Shifter Bushing
5VZ Aisin pressure plate mated to a 3rz Aisin clutch disk

Some of the Parts:


I'm going to attempt to make my own exhaust and IC piping out of 16ga mild steel mandrel bends. So we'll see how that comes out. I've messed with welding here and there and this will be my first attempt at piping. Most of what I am doing isn't ground breaking work, so I'm definitely not trying to make it appear that way at all. I've done a couple turbo setups in the past so i'm trying to apply some of that old knowledge here in what I am hoping will be a fun project.

I got somewhat started yesterday. I'm still waiting for my turbo and manifold to arrive so I thought I mess with some of the other stuff in the engine bay a bit. The only new part installed was the pink top injectors. However, I planned on deleting the EGR system since the treadstone manifold doesn't have an EGR outlet. This combined with the need to remove the TB in order to get better access to the injectors, I decided to remove the intake manifold completely, clean up the runners a bit, install a new fuel filter and delete the TB coolant lines as well.

What I started with:


Out with the browns


In with the pinks


Water lines capped off:


EGR out



Reassembled for test drive to make sure everything is working properly. I still need to put in a 10K ohm resistor in the EGR sensor plug trick the ECU into thinking it's still there. Right now I still have it plugged in just w/o any exhaust gasses being recirced.

 

aaaaaaannnnddd

 

Second beeotch

 

Saw that...Thought just once I could have it....

 

A few pics up now. Hoping to get the fuel pump in tomorrow and start fitting the IC. Then it's just waiting for more parts to arrive. Bends come on Tuesday, Mani and turbo on Thursday.

 

Got a little done this morning while I'm still waiting for more parts to come in. Swapped out the fuel pump for a Walbro 190. Only took a little over an hour. Hopefully everything else will go this smoothly.

 

Got my FMIC mounted up today and Sawzalled some holes to run the piping through the radiator support. Tacked a 1"x1" square tube between the frame and added some tabs to it. I just need to finish cutting the back side of the bumper to fit it over the IC.




Also received this in the mail today

 

Finished trimming up the bumper this morning. Got it fitted for now, until I take it back off to run the IC piping.

 

Looks good!

 

Got some disassembly done yesterday.

Dropped the front diff to get to the oil pan. This time went much quicker than when I re-geared a few months back.



Also got the stock intake and exhaust manifold off as well. Pretty straight forward. Mani actually had no cracks!




Afterwards I had some time to finally put on my Wheelers Offroad SS Brake Lines that I've had sitting around since February. Having the Exhaust mani out of the way definitely made it much easier.


Now I'm just waiting on UPS to get my Turbo manifold and oil lines in. From there I'll be able to get my oil pan drilled out and bung welded in once the turbo placement it determined as well as begin working on IC and Exhaust piping. hopefully all of that will go as smoothly as everything else has up to this point.

 

Finally got back onto TW after being gone for a while...looks like you've made some darn good progress there. Looking forward to seeing you get everything up and running!

 

Thanks Sam. Thanks again for all the info as well. I've kind of been at a stand still this week with it. We've had family in town so I haven't had much time to be in the garage. Plus I received a couple incorrect oil fittings so I'm waiting for the correct ones to arrive here soon so I can start some assembly. Hopefully I'll be able to get a little done this coming weekend and start some piping next week. I have a bunch of mandrel bends just waiting along with my mani and oil lines...

 

Today I was swapping springs in the wastegate when I noticed that the diaphragm looked as though it had been pinched at some point. So when I looked under the pinched area I saw that it was indeed torn
So I ordered a replacement from Amazon which sucks to need to do, but I guess that's just part of buying used stuff sometimes. I'm just glad I caught it now and not when I was over boosting my motor

 

Hell yeah, turbo'd 3rz build. Good luck and keep it up!

 

I was able to get some more work done this weekend. After much research on trying to find the correct oil feed line fitting, I finally just used some common sense and measured the plug that it would be replacing. Turned out it was 18mm so I used a M18x1.5 adapter for a 3SGTE that fit perfectly. You can see it in the pic the original plug I replaced next to the M16x1.5 that most of my research led me to.


It's nice to finally have that in so I could begin fitting the oil return line as well as the manifold and turbo itself.


Oil return shortened with the 10AN female fitting added to it.


Oil pan reinstalled with the 10AN male fitting welded, painted, and mated to the turbo return line. I used The Right Stuff for the oil pan gasket.


Turbo, Manifold and oil lines finally installed. I also put the front diff back in as well this morning. I mainly just need to fab up the plumbing and install the gauges now along with a few other odds and ends


How it currently sits:

 

I started working on the plumbing this morning. I was able to get the hot side IC pipe done and almost got the downpipe done. I just need to weld in the O2 sensor bungs and the DP will be complete. I'm waiting for a couple more couplers to get the cold side IC piping figured out, then I need to make a dump tube for the wastegate and install the gauges. After that it will just be making a cat back exhaust. Right now the DP mates up to the stock exhaust so I can run it that way for a bit for trouble shooting purposes to start. Here's some pics:

Cold side IC pipe. This was my first welding of any kind of piping. Looks rough but is functional


After some grinding and paint:


Down pipe. Welds were still a little rough. Improved a bit as I went. The 2 bolt exhaust flange weld was probably the best (b/c it was the last of course).

 

Will your front bumper allow sufficient airflow through your IC?

 

I'm figuring for lower to moderate boost it should flow ok enough. I've thought about taking a hole saw to the upper portion and putting a few holes in it to help it out. With the IC being 3.5" thick, I'm hoping it won't need a ton of direct air flow. I'll what my AIT look like once I get it going and go from there
