Background
I started out as a young 18 year old just looking for a car to get me from A to B. After seeing how reliable a civic was for my older sister I almost made the mistake of buying one. Then, flipping though the auto trader I saw my first mk3 supra. The moment I saw the car I instantly knew I was going to have a supra. I started off with a 89 NA which had too many miles to count and left much to be desired power wise. As I got to know some of the Supra community I got my first ride in a 89T which was BPU'ed to over 330RWHP. Later that month I took out a lone and had me a 87 Turbo Targa which was in show room condition. My first base line dyno was a very sluggish 212 RWHP 255 TQ at 10 PSI with usual BPU mods. I later discovered that I had low compression in 4 of 6 cylinders even though the engine had only 94,000KM on her. 1 year later I opted to swap in a JDM engine along with a 1.2 MM HKS MHG and ARP Studs. I then added several other modifications and was able to achieve 307 RWHP and 406 TQ at 16 PSI on the stock turbo. However, this still wasn't enough.... While down for the winter that year I decided to go with a turbo upgrade as well as all the supporting modifications to utilize the bigger turbo.

Writeup
Starting to work on supras was very challenging since, I had never taken any auto courses. In addition I had no previous mechanical skills. The first time I dug into my supra was to do the infamous HG re-torque with a local supra member. After learning that the 7m-GTE wasn’t just a rats nest of wires and hoses it was fairly easy to work on as long as I kept my Toyota service manual close by when I got stumped. I took out a line of credit for the supra which grew each day of supra ownership, since I couldn’t control my E-Bay spending habits. I first started mods to my already BPU car by adding electronics such as the AVC-R and S-AFC. I then continued to slowly modify my car to the point where I was just under fuel-cut. After knowing I had more juice left I ordered the parts I needed to circumvent fuel-cut and upped the boost to the point where I maxed out the stock turbo. Before giving up on the stock turbo I was able to leave rubber patches in first, second and third by just stomping the gas at 3500 RPM. This of course brought a smile to my face however, the upper power range seemed to lack. After gathering up all the parts to build my car around my new planned turbo I hit many road stops since, I had many custom things fabricated for me. (Brackets, adapters, flanges, etc.) I was able to get the car out only a few weeks behind schedule. The first trial run was heart thumping since I had to make sure I had no loose connections, leaks or other problems. I set the boost control on off and the base fuel pressure to 45 just to be on the safe side. When I hit the bottom of my street I hit the gas only to be greeted by the sound of a open turbo screaming with only a piece of sheet metal to deflect the exhaust gases down the firewall. The nice roar of 7M-GTE put me back in to my seat however, I was craving for that extra neck wrenching G-force that the t04B should deliver. However, I was disappointed because I felt nothing.  Did I set something up wrong? What did I do? Then I remembered the size of my turbo and the rpm I was letting off at.  Noticing that I never surpassed 4000 RPM I figured what the hell, lets try this again. Glancing over a the AVC-R I noticed the throttle position at 100% and the rpm rising to the 4000 mark. Then all hell broke loose, tires started spinning, and my car started flapping like a fish out of the water. Instantly a grin from ear to ear overcame my face. After working out the bugs I jumped on the dyno. I was very impressed with the numbers I got since I had pushed the stock Intercooler further then anyone else and had done it all own two hands.

Future plans
My plans for my car as of right now are not set in stone for power mods. I’ve been thinking of doing a 7mGTE swap to a mk2 supra or a 2jz mk3. I’m also considering building up the 7mGTE. I only have a intercooler planned this year. However, I am planning to break the 550 RWHP with my current. I’m however, concentrating currently on the exterior and interior looks of the car. Trying to clean up the mess I left in the engine by replacing, cleaning and polishing all parts. I’m also working on reliability of the car to have it more reliable then stock.
