Blueprinting a 1000hp 2JZGTE Motor

Owning a fourth generation Toyota Supra comes with its own ups and downs.  Most owners find themselves between a rock and a hard place when it comes to modifications.  Due to the extensive power potential of this platform, it becomes difficult to hold back and limit oneself to a few simple modifications.  If you’ve ever owned one of these fabulous vehicles and answered someone’s horsepower question with “Oh, I make about 450 or so…”, I’m sure their response would be:  “Why aren’t you making 1000!”.

So then the quest for more power begins, and before you know it, you end up reaching the limitations of this stout motor.  Some folks blow their motor to pieces, others spin bearings, and yet others rebuild their motor right from the start.   In my case, I was rather lucky.  Having dynoed nearly 800 whp at 28 pounds of boost and nearly three years of constant abuse on an otherwise unopened motor, its time was due and catastrophe occurred.

It started with a sound, the all familiar knock sound one hears while revving the engine.  After dozens of checks for the source, no apparent signs of damage were seen.  Heck, she still ran fine on the road!  I decided to tear her down and investigate.  That was when I found six lovely bananas (Where is the violin!):

It happened one lovely afternoon when I decided to raise the boost to 34 Psi. I reckon she was near 850 whp, but that is only speculation. She pulled very hard, and I remember feeling a slight hesitation, but thought nothing of it. It was quite possible they were already bent from previous endeavours. It was time. Time to take on a new challenge and build it better, stronger and faster. Unfortunately, being hands on like myself has its drawbacks. I have issues with the outside world when it comes to my baby. Leaving her in the hands of mechanics sends shivers down my spine. It was time to face this rebuild myself.

Follow along as I build a motor from the ground up, hoping to prepare for a

marvelous 1000 whp beast!

’93 hardtop supra turbo

Hello readers at MKIV.com I’m Mario and thought it’d be nice to share something about my own supra and how she has been evolved since my ownership.

I own an originally Red june-1993 supra SZ which was bought by me when first imported into the Netherlands back in august 2009.

Since my ownership the car has been undergoing a few major changes, for example the 2JZ-GE got exchanged for an 2JZ-GTE, also the 5-speed W58 got exchanged for an 6-speed V160 in combination with an A02B differential.

While the previously fitted 2JZ-GE was taken out of the engine compartment the supra was sent off to the paint shop to get the engine compartment resprayed.



Installation of my 4” HKS Titanium exhaust system, customized for more ground clearance.



BPU’d the 2JZ-GTE and upgraded the j-spec 2/1 pot configuration into the ‘’US-spec’’ brakes all round.
The system exhaust got upgraded to an 4’’ HKS Titanium.
The supra is recently completely overhauled, the previous owner(s) resprayed the supra in a goldish, top-secret ish color with an aftermarket body kit. I wanted to get the supra back in her original shape with only OEM exterior parts. The supra received a full overhaul and is sprayed in Toyota’s 040 white, during the overhaul she received new window seals and installation materials as bolts, nuts, clips etc. Also she received OEM facelift lightening all round. Also new CCW wheels got fitted.

A few pictures of the restauration and how she sits at the minute, I will let the pictures do the talking.

Exchanged the final drive from A02B>B03B this included the prop/ and driveshafts to be exchanged as well.


While at it the stock old brake lines got exchanged for the HKS braided lines,


Still lots of things in mind, will keep you updated.

3D Toyota Supra
in High Detail

By Jay Xiong

A featured 3D Toyota Supra model? Why? There’s nothing particularly special about it. It has been done hundreds if not thousands of times by others for games, movies, fan art, etc. in various levels of quality and detail. So what makes this one stand out among the rest? Well, it’s all about what kind of Artist is behind such a project.

Hi, my name is Jay, and I had wanted an mkiv since the day I first laid eyes on one at a Connecticut highway gas station back in the spring of 2001; I was only 17. I then drew countless pictures of mkivs, collected almost all the scale models, and even saved as much money as I could in hopes of being able to afford my own someday. I saw all the movies with Supras (that I know of), watched all kinds of Supra vs.____ videos, often stayed aware on the road for possible Supra sightings, and I even made my own Supra comics. I talked about mkivs so much that “Supra” was practically my middle name. You see, this 3D Supra is different because it’s being modeled not by a regular Joe who simply likes mkivs but by an insane, lunatic Artist who has

worshipped mkiv Supras from day one.

So three years after discovering 3D Modeling, I dared myself to model the most detailed 3D mkiv Supra; I wanted to do this historic vehicle justice and help make it shine in the CG community since the majority of 3D Supras didn’t look quite right (go research it yourself). These artists had far greater potential but weren’t giving the Supra the level of attention it deserved. So I spent many nights up late and pulled numerous all-nighters, but modeling mostly around my busy schedule, it quickly became an every-now-and-then project, so what you see here has been in progress since 2009.

This 3D Supra was not made by commission nor for any sort of profit but made by an absolute fed-up maniac of an mkiv Supra fan (who is also now a proud 6-speed mkiv owner) purely for fun, and of course, just to say he did it. My hope is that you will appreciate (even if just a little) all the fine details I have crafted into this 3D model. I have used literally thousands of photo references (many of which were taken by myself) to ensure the model is as accurate as possible. With that in mind, however, capturing the exact dimensions & specs to the dot was not and is not the point (it’s impossible anyway, especially with polygon modeling). My goal is only to make it believable even to the trained eyes.

So pick it apart! Tell me the inaccuracies and problems you see, and I’ll make sure to fix up where needed. FEEDBACK PLEASE!! As of the date of this post, this model is about 90-95% completed as far as interior and exterior. The engine work as begun, and so far, it’s terribly brutal. From here on, it will mostly be engine updates. I cannot possibly know every single piece involved in the engine’s assembly (I’m a fan, not a mechanic), so your input would be greatly appreciated. So without further ado, enjoy this blog and its progress shots!

Here it is… quite possibly the most detailed 3D Toyota Supra you’ve ever seen:

I love Advan T7s, so I might put these on for one of the final renders just for fun.

MKiV Twin Turbo Sequential System

One of the unique new features of the MKiV Supra was the Twin Turbo Sequential operation. Only a handful of cars touted this Sequential System. The system was designed to provide greater power levels at lower RPMs by diverting all the exhaust energies to the front #1 turbo. Since these turbo’s are rather small, running on one turbo provided a high spool characteristic. At or around 4000 rpms, the rear #2 turbo would kick in to provide for the peak potential power.

With this unique system comes complications. There are a lot of components that go into this system. If any of them malfunction, the entire system goes down. The “orchestration” of Actuators, Vacuum Switching Valves (VSVs), and vacuum lines via the ECU is a

real feat. As our beloved MKiV Supra ages, so does the Sequential System. Vacuum lines become brittle, actuators lose there ability to hold pressure, VSVs start to break down, Pressure tank loses it’s ability to store pressurized air. All of which is needed to have the system work.

Understanding this system can be somewhat complicated and difficult to diagnose. Several years ago I wrote a diagnostic manual to help people try to understand how it works and help find issues.  http://97supraturbo.com/public_html/Seq%20FAQ/Seq%20FAQ.doc  This doesn’t cover 100% of all possible issues, but it covers the most common. If anyone is serious to understanding and diagnosing the Sequential System, I highly recommend to purchase a MityVac hand pump. Like the MV8510 series. http://www.lincolnindustrial.com/asp/distributors/access/distributors/4_MV8510%20PIS.pdf. You will be able to test all the components with this. Find leaks, and actuator healthiness. As well as testing the pressure tank.

This all should aid you into figuring out issues.  Your going to find that there is not many dealers/repair places out there that can understand and repair effectively, so the only person that can really get to it and fix things is YOU! Good Luck.
