Welcome to my new build thread! My original build thread can be found here: http://www.supramania.com/forum/threads/2jz-ge-t-build-89-turbo-supra.73968/
(DISCLAIMER: Thankfully, a lot of growing up happens over the course of almost 12 years. Please excuse some of my shenanigans and my lack of quality. A lot of decisions were made in haste during that build so, needless to say, there are a million things I wish I would have said and done differently.)

I wanted to make an updated build thread for a couple of reasons. 1) I want to make sure I'm doing my part to contribute to this community. Just in case there's someone out there who might be interested in doing a similar swap. 2) The clean slate helps the future of the build feel more possible.

The goal with my car is to restore its GT glory with 450-550 RWHP on pump gas, and 550-650 on E85. The idea is to have the car set up in such a way that it's equally capable of a nice road trip for my wife and me, as it is for a spirited drive with my buddies. I'm not building this car to make crazy stupid numbers or to set any track records. I've owned my car for nearly 15 years and at this point, it's more of a companion than a tool for the track.

Future plans for the car: ECUMaster Black, FFIM, upgraded fuel setup, 2JZ VVTI coils, new turbo manifold, new turbo, new wastegate, new harness, repair A/C, have Nightrun rebuild the steering rack, refresh front with new bushings... And I think that's all that I can recall at the moment.

Thoughts on the build so far... I'd say this approach to the 2JZ world is more accessible, but it comes with some caveats and risks. Mainly the timing, manifold & turbo options are a bit more narrow and some require clever solutions. All in all, I've had decent success with this build and it's lasted quite a while.

I completed the first version of this build in August of 2008. The details are as follows:

89 turbo car - white package with burgundy interior.
- 2JZ-GE Completely Rebuilt
- XS-Power NA-T Kit
- "T61" Turbo
- Southbend Stage 3 Full Face Clutch
- 1JZ Bellhousing
- 1JZ Flywheel
- Apexi SAFC Neo
- AEM Eugo
- Prosport Boost Gauge
- 7MGTE Components Used: 7MGTE injectors, coil packs, radiator hoses, AFM, CPS, AC Compressor housing top, radiator, fan(?)... I'm sure I'm forgetting something.
- 2JZGE Components Used: Engine set, fuel rail, all accessories... again, I'm sure I'm forgetting something.
Power came in at 374HP & 324TQ @ 10psi.

Things that have been done over the course of the last five years.
- Fortune Auto 500 Series Coilovers.
- Arizona Performance Front 4-Piston Big Brake Kit
- Upgraded to an ECUMaster DET3 and eliminated the AFM.
- A complete rear subframe refresh with OEM bearings and polyurethane bushings.
- Mishimoto Radiator
- Mishimoto Racing Thermostat
- Rays Gramlights 57CRs in Gun Blue II - 18x9.5 ET 38s on all four corners. (275/35-18s in the rear, 255/35-18s in front) No rubbing when turning lock to lock. Occasional rubbing on compression while turning.
- YodaConnectors FBE Box & Fog Light Rewire
- Motor mounts from DriftMotion
- TiAL 50MM BOV
- HPS Radiator Hoses
- Sleeper Designs Radiator Brackets

The first job to document - the subframe work.

I felt a general floating sensation in the rear any time I drove the car. I also felt wheel hop when the rear passenger wheel hit a small bump. Most likely due to the leaky shock absorber back there, but I also looked at the factory bushings and decided it was time to do a full refresh. This job fought me at almost every step. Aside from the regular issues that come with a subframe refresh, like difficulty in removing bushings, the biggest roadblock came when I realized the passenger side axle was frozen inside of the hub. I used heat, a slide hammer, more heat, more weight on the slide hammer -- and yet the axle remained firmly in place.

I took it up to a dealership where my buddy was kind enough to through it in their press. We took the time to get the hub assembly placed properly into the press. We put a nut on the edge of the axle and 1/3" metal spacer between it and the press. We crank down until we cant crank anymore -- nothing. We try again -- nothing. We use a torch and heat it up, then start cranking -- nothing. The fourth time, we try the same process, start cranking, and *SNAP*! First I felt relief at finally removing this thing, only to find out that we broke the knuckle. Then we see the threads on the axle were warped, so I call up my buddy Zach who had another assembly in his shop. (Side note: after the hub broke and the axle threads were toast, another friend took an air hammer to the axle and finally got it out.)

Then we ran into part availability issues. All in all, it took about 2-3 extra weeks to complete. But while I had everything disassembled, I stripped, primed, and painted almost everything in the assembly.

Parts:
- Subframe bushings from GT4 Performance. The fitment was super tight, even after spending about 24 hours in the freezer to shrink them, and with the assembly lube. I used the factory washers, a long bolt, and an impact driver to pull the bushings in to place. It was a bear, but it worked.
- Energy Suspension bushings for the rest of the polyurethane bits.
- Spherical Bushings from Toyota.
- Wheel Bearings from Toyota.

I reinstalled the old KYB and ST spring setup I had, noticing that there was a significant leak. It made the purchase of the Fortune Auto 500 series necessary, but I just didn't have the funds at that time. So I had the car aligned and it felt so much better - even with a blown shock.

Are you going to reinforce the subframe around the rear diff?

I"m envious. So wish I'd done the sub-frame back when. We'll be watching :}
Thanks for tuning in, man!

Great stuff, love a good restore build
Thanks! Glad the subframe is in a good spot. Now to focus on the rest of the car :oops:

Are you going to reinforce the subframe around the rear diff?
I did not. I thought about it when it was out of the car, and ultimately with time constraints and needing to get the car out of the garage, I opted not to do it. I saw some folks reinforce theirs, and it seems like a fantastic idea. I suppose I should have clarified, this job was done in the winter of '17.

Next was a relatively easy install - the Fortune Auto 500 Series coilovers. I opted for the upgraded locking spring perches after hearing too many stories about the two collars being seized together. I saved a bit by not going with the Swift spring upgrade, and I figure I can do that later if I'd like to. I ordered these through Nightrun Garage and I couldn't be happier with their service, or with Fortune Auto's product. Really top-notch stuff.

This was the fall of '18, and I was on the road working when these came in. My wedding was approaching quickly in December of '18, and my wife and I arrived in town only days before the ceremony. As we all know, the work on the car rarely ever sticks to the arbitrary time tables we set for them. My option was to install them right after Christmas day, 3 days before the ceremony, and that just had disaster written all over it.

I sheepishly asked my best man if he had any time to do the install, so I could leave my focus strictly on the wedding and any last-minute details. He is indeed the best man.

He told me it was a super easy install, which it was most likely going to be. I just didn't want to roll the dice so close to the wedding. The Supra was our getaway car, so naturally, it needed to be in tiptop shape.

I had been running on the KYB / ST Spring combo since '08, and the last 4 years were on a blown rear shock. I rarely drive the car given my job, but when I did, it was painfully obvious that the coiovers were a must. The car was COMPLETELY transformed. It doesn't feel like a boat anymore, and it handles better than I ever thought it could. The soft setting is super compliant, so much so that I actually prefer setting 20-21 on all four corners.

After we got the car sitting properly, it was time to ditch the NA MKIV wheels. These served me pretty well over the course of the last 11 years, as long as I was careful about going full lock. I did not run spacers, like a fool. I have a few marks on those wheels, as well as my control arms to pay for that omission.

Like many folks, I searched and searched, then searched some more for the right set of wheels. After the better part of a year went by, I settled on the Enkie RFP01s. They weren't exactly what I wanted, but they were lightweight and would suit the car better than the NA MKIV wheels.

But then... I was bored one day and looked on Rays website and discovered the Gram Light series wheels, and fell absolutely head over heels for the 57CRs in Gun Blue II. I couldn't take my eyes off of them. I began looking at the cost and weighing against the RPF01s. I knew the Enkies would be a temporary wheel. The 57CRs, however, felt like wheels I could see on the car forever. With that in mind, I decided to spend a bit more, and get the wheels I felt belonged on the car. After many, many conversations with Rodel, Doug, Andy, and my best man Jason, I decided to go with 18x8.5 ET37 up front and 18x9.5 ET38 in the rear

However, due to availability, I realized quickly that I needed to change my mind about the front if I wanted these installed by the time my wedding came. I upped the width in the front and found all four with David Kim at a company called Aristocrat Autosport. Fantastic customer service. The best man coming through once again, and had the tires mounted, and then installed them on the car.

Final specs:
Front: 18x9.5" ET38 with 255/35-18 Dunlop Direzza Tires
Rear: 18x9.5" ET38 with 275/35-18 Dunlop Direzza Tires
(With appropriate wheel spacers.)

Under compression and cornering at speed, it does interfere in the front. However, it clears lock to lock when parking.

Nick, love it. Keep up this format. Perfect mix of details, context and pictures. Really cool to see it progress. I can't wait to see where this thing ends up!

Side note in case you haven't already tackled this. I recall you contemplating what to do a while back in another thread. I just removed the clear protective film from my rocker guards in front of the rear wheels. I fought with them for HOURS.... until I got them warm enough. Once I got the film up to temp, the entire sheet just peeled up perfectly and effortlessly. I think the adhesive softens well below the melt point of the plastic so you just need to carefully work up to that temp. I was amazed how easily it all came off once I got it in front of my space heater for 5 minutes.

I appreciate the feedback, Andy! I cant wait to see how it ends up either! I think the next big job will probably be started in April, and will most likely be the FFIM, Fuel, VVTI Coils, & PS Res relocation.

Seriously?! I'll have to try that. The rocker guards still look atrocious on my car, I'd love to get those off. I'll have to try that when I"m around the car in December. Thanks for the tip!

Next on the docket was to fix an exhaust leak that had developed between the turbo manifold and the cylinder head. (Spring 2018

In 2008, while at college in Indiana, I had the same thing happen. A stud pulled out of the head, so I worked around the turbo and the manifold and drilled and tapped for an M12 x.x bolt. I was in a pinch and I needed the car fixed. Not my finest hour.

I figured the same thing happened, but in a place where the turbo and manifold needed to come off. Off everything came. I purchased a 90-degree drill attachment, thread insert(s), and got to work. The drill, tap, insert, and new stud worked great.

Unfortunately, upon reassembly TWO MORE pulled out… This was a long week. Few things are worse than when you’re tightening a bolt/nut and feel everything go loose. Pulled the manifold back off and drilled and tapped two more holes. Installed thread inserts, studs, tightened them down to spec, and everything went well. The turbo was a massive pain to reinstall on the manifold. Also, my downpipe felt like it was in a bind, and was exceedingly difficult to reattach to the rest of the exhaust. — (One of several hints that the next job was necessary. I’ll post that one soon.)

*Side note* Anyone else with a 2JZGE in an MK3 — What turbo manifold are you using, and is it as much of a pain to work with as this one is? Or does every manifold come with its difficulty, aside from units with a V-Band flange?

Also, how should I address this M12 exhaust bolt situation? I’d love for it to be an M10 stud again. My guess is a thread reducer, or a stepped down stud. Thoughts?

I would use a time-sert to fix the threads to accept the original size stud.

Also I would recommend clocking your turbo chra so the oil drain is vertical.
If you keep it the way it is right now, oil has a tendency of pooling in the chra and leaking out the turbine seals and or laberenth seal.
You have it at a pretty heavy angle right now.

Somewhere...

Basically Helicoil isn't it? I had to do that on my first supra, worked like a charm.

Not really. But it's the same concept.
The time-sert is much much stronger, a solid piece of metal.
Helicoil is obviously a coiled up piece of metal.

XofX, are you saying the M12 hole you tapped and helicoiled also pulled out?

You could take it to M14 and use a reducer to bring it back to M10.

Another option.
There are a bunch of different styles of reducers out there.
I'd have to look closer in there, but I'm nearly positive that my 20 year old self just drilled, and tapped the aluminum...? I don't recall using a thread insert back then, but it was 11 years ago so perhaps I did and I just dont recall. Thanks for sending those! It's good to know there are options. The current M12 bolt worked, and was torqued down. Ideally I'd like to put an insert to make it the correct size and install a stud.

About the turbo... I've tried so many different ways to clock that thing where the drain line clears. The way the tubro drain is placed, the AN hose fitting interfers with the T4 flange. That's as far downward as I could place it. I'm sure there's a solution with a fitting that will work. Either way, you're 100% right. I think that was a contributing factor to my previous turbo biting the dust in 09.

Yup, wished I'd have known it ahead of time. I heard from many folks it's a terrible job so I was ready with all kinds of tools and chemicals. I tried adhesive remover (terrible), metal scraper (terrible), plastic razor blade (ok) and then finally put it in front of a space heater (perfect). In 5 ish minutes I lifted a corner and it just peeled off like a fresh electronic screen protector. You'll need adhesive remover and/or a patient thumb at that point to get the final film of adhesive, but it's cake at that point.

A Tale of Two Turbos

As I mentioned in my previous progress post, it was quite difficult to reattach my downpipe to the rest of my exhaust. Also from my previous job, the turbo and the drain line were even harder to re-install than I remembered. Another cue - was my intercooler piping now interfering with the strut tower and inner fender. As if that wasn’t enough, I also developed a drivetrain clunk at parking lot speeds that previously was not there. It’s almost as if my car was trying to say “Pst… Things are weird… You should think harder about this…” It only took four symptoms for it to finally get through my thick skull. It occurred to me in the gym in Cleveland, I grabbed my phone to run the thought process by my buddy, and shortly after that, the motor mounts were on order.

Along with the mounts, I purchased a new TiAL 50MM BOV, HPS radiator hoses, AN hose with fittings to redo my drain line, and OEM rubber stops for the hatch. I had a flight back to Texas booked to film a few things with a company I’m working for called RumbleOn, so I figured I’d take a day and knock this job out. I’m certain the Supra laughed at the 1-day timeline I assigned to the job…

We drained the coolant, disconnected radiator hoses, removed my coil packs, unbolted the mounts, and started lifting the engine up with a hoist. Mounts came out super easy, and BINGO — passenger side mount was in two separate pieces. New mounts went in super easy, but next came the drain line, and that’s where everything fell apart. We started by taking the compressor housing off of the turbo, and the o-ring sealing the compressor housing to the CHRA completely split in two, so I used this as a sign that the turbo could stand to be replaced. Was it completely blown? Nope. Is it tired? Absolutely.

Options were a little limited during the week of SEMA, so we went to our local Summit Racing and picked up a VSRacing T77. As you can see, the compressor housing interfered with the front runner of the manifold. Could the housing be cut and welded to work? Sure. Did we want to do that? Nope. Summit was awesome and allowed me to return the turbo. I swapped it out for a Borg Warner S366. It cleared the front runner and we were good to go! But it interfered with the GE throttle body... it was a long shot anyway. Back it went to Summit who again, was awesome. Especially since I opened the box like an ape.

Majestic Turbochargers came through with a new o-ring seal that we were able to make work. Tremendous customer service all around. So, the XSPower “T61” will live to fight another day!

Is it better to have loved and lost a turbo, then never to have tried installing a turbo that was entirely too big for my purposes? My answer: Yes. We learned a lot with this trial and error, and it made the future of the build feel possible. It also taught us that whatever the future of this build is: the turbo and both manifolds have GOT TO GO.

The new mounts, the hoses, the TiAL all make the car feel fantastic again. I’ve fallen in love with the sound of the TiAL.

(For the eagle-eyed reader, I also installed the SleeperDesigns Radiator Brackets.)
