Background
While cruising along in my mint early ’86 MKII Supra, I spotted this black ’92 Supra turbo at a car lot. I stopped to take a look and was amazed by its condition inside and out. The black/shadow grey interior was perfect and so was its black exterior paint. This car was completely STOCK! I took it for a test drive and thought it drove perfectly. Next thing I know, it was in my garage, jacked up for further scrutinizing. After finding that everything under the car looked very clean and undamaged, I immediately drove it back to the car lot and started going through the process of trading in my ’86. Although I was a little hesitant to get rid of it, I thought I will get more fun and excitement from its new replacement. Little did I know that it would turn into what it is now!

Turbo
Got tired of the stock CT26 and went with a TO4E. A little while after that, I got power hungry and decided to go with a bigger ITS dual ballbearing GT76. Q trim. .84 AR.

Bottom End
The bottom end on the 7MGTE has a stock crank that has been semi knife-edged, balanced with Cunningham rods, coated JE pistons, and Toyota bearings.

Head
The cylinder head is completely stock. A 2MM HKS metal headgasket and ARP head studs torqued to 90 lb-ft keep it sealed to the block.

Intake
I decided to make my own custom plenum that simplifies intake air routing. I use a Tial BOV to protect the turbo from compressor surge. The intercooler consists of the largest Spearco core that will fit and custom end tanks. The aluminum intake pipes from the turbo to the throttle body are also custom made.

Exhaust
"ONE OF A KIND" best describes the TIG welded all 321 stainless header. Runners are 1.625” in diameter and have .065” wall thickness. It uses two Burnsstainless 3 into 1 collectors. A Tial 46mm wastegate is used to help control the boost and a custom 3.5 inch downpipe, full stainless steel exhaust  with Burnsstainless lightweight race muffler with custom Inconel tip complete the exhaust system of the Supra.

Fuel
Fuel is delivered by an SX external pump and controlling its pressure is an SX regulator. The fuel lines are custom made 1/2 inch stainless hard lines and stainless steel braided teflon lines. A stock fuel rail with custom fittings is fitted with a set of Bosch 800cc injectors.

Drivetrain
Transferring the power to the wheels is a stock R154.  The lightweight JUN chromoly flywheel was modified to work with a Tilton Triple Carbon plate clutch. The combination of these two parts weighs only 12 pounds! The driveshaft is now one piece which is lighter than the stock two piece design. A Torsen LSD and a MoTeC Traction Control system make sure the tires are put to good use.

Suspension
For quick turns or just playing around town, the car is fitted with a set of HKS coilovers, ST swaybars, and a set of Nylon bushings. And to stop on dime, a set of 14.1” MKIV Brembo Gran Turismo kit was custom fitted.

Electronics
Controlling just about everything in the electronic aspect of this Supra is a MoTeC M820 ECU. All parameters are logged and monitored using a MoTeC DASH LOGGER. With Aquamist H20 injection triggered by the ECU, detonation is almost impossible. Boost pressure is also controlled by the MoTeC ECU via GM boost solenoid valve, using a Speed and RPM or Gear position based boost table. With all kinds of compensations using all the sensors within the system, the 7M is sure to run smooth and efficient all the time. Ignition is fully sequential using six individual MKIV twin turbo coil-on-plug setup. The coils are fired by a GM 6-channel igniter.

Interior
For comfort and performance, I decided to go with a pair of Recaro SRD seats. A MoTec dash logger now covers the stock tachometer and speedometer. A Sparco steering wheel along with few trick toggle switches for lower RPM limit, speed limit and traction control finish up the simple yet functional interior of the car.

Exterior
I’m still happy with the factory Black paint. This car will never be painted with any color but Black. Wheels were replaced Kinesis K58Rs. Rears are 18 X 10 and fronts are 18 X 9. These are wrapped with Bridgestone SO3s, 285 30 18 rears and 265 35 18 fronts.

Writeup
I learned a lot of things while working on this car. All the parts, custom made or not are all what I pictured them to be. It took a lot of planning and dreaming to get it to where it is now. I had one goal and I stuck to it. It is now “almost” done and I’m just beginning to really enjoy owning and driving it. It will definitely be in my possession for as long as I’m able to drive.

Future plans
An OS Giken gear set will definitely be in the future if I ever find one. A custom TIG welded Roll Cage is in the plan along with a full set of tubular chromoly control arms. Maybe a custom tubular rear subframe that will be ligther yet stronger than the stock one. A very subtle body kit made from carbon fiber might be in the near future.
