The first problem I had to fix was that the car was in "TTC", which stands for "True Twin Conversion" when I bought it. This modification makes the first turbo wait to come on until the point when the second turbo normally kicks in (~4300RPM). This gives the illusion of more power, at the expense of more lag. In reality, there is slightly more midrange in TTC, and about 4 peak RWHP gained, at the expense of ALL of the car's low end. Sequential operation yields FAR more area under the curve, and overall, a faster Supra.

The next problem to fix was the green coolant in the radiator/cooling system-Ugh! Green coolant contains silicate packages once thought to improve cooling. In reality, they do nothing to help with cooling, and can actually clog some of the smaller coolant passages in the engine/radiator. I had the local dealer, Royal Moore Toyota, do a power flush of the system, and install .5 gallons of Toyota Red Long-Life coolant, with a pint of Redline Water Wetter, and the balance of the system was filled with new distilled water. The top radiator hose was replaced with a 1998 hose, which was improved by Toyota to prevent the hose from sagging down and making contact with the accessory drive belt.

In addition to these changes, I also put new Toyota V-160 fluid in the 6 speed Getrag transmission, and Redline Synthetic 75W-90 gear oil in the TRD limited slip differential.

Denso IK22 spark plugs have been installed, gapped at .028. These are one heat range cooler than stock, which is recommended for forced induction engines running higher than stock boost.

I also spent most of a day washing, polishing, and then waxing the Super White paint. The paint was VERY dry, since the car came from Arizona. It took 3 coats of wax to get a good shine on the hood!

The cigarette lighter socket was burned out, from running an air compressor. I replaced the socket. The next project I have slated is replacement of the lame stock stereo, which has a blown speaker in the passenger side door, and won't play past track 9 on the CD player.

(2/14/2006) Update: I installed all of the sensor pigtails, and prewired the car for the AEM UEGO, while removing the Greddy PRofec B, and BCC. I dropped the car off at RRev Motorsports for a week, where the wideband sensor and EMS was professionally installed and tuned. I have the car back, and am thoroughly thrilled with the performance. The car is making right about 400RWHP on pump gas, and about 430 on race gas, at the same boost level. We are going to install a GM boost control solenoid, and see if we can squeeze a few more PSI out of the stock twins to get to 450RWHP.

(Summer 2006) We installed a methanol injection kit, which brought the car to 450RWHP on pump gas+methanol injection.

(Summer 2007) Purchased a set of M&H drag radials, and managed to twist two stock driveshafts in half with the additional traction. Started looking for a source for a 1 piece, Detroit style driveshaft. Purchased, upgraded and installed a small single kit. The car made 470RWHP on pump+methanol. Attended SILV2007

(3/1/2008) Installed the custom GT4088R kit from http://www.atsracing.net. After a retune by John Reed at RRev Motorsports, the car made 465RWHP on pump gas, at 17PSI, and 582RWHP on pump gas+methanol injection, at 25PSI. The car is fuel-limited on both maps. Next Winter I will install the SARD 800CC/min PnP injectors, with a larger fuel pump from Apexi.
