2000 GS400 build
First off... have a very well maintained car with regular oil and trans fluid changes; 5k and 30k respectively.
Installed GS300 rear end, and I beefed up bolts holding it in place and car is now like a rocket ship.
Rear end went from 3.266 to 3.916... ie about 65 increase in ft-lbs of torque at rear wheel.
Cold Air intake.
High flow CATs
Now I'm installing headers.
If wife doesn't find out... maybe the SVT supercharger.
