Man, you do not want to be running a stage 2 turbo kit on stock suspension, the TVS kit will dramaticly improve handling and keep your car stable durring high speeds (no more floating feeling) plus cant that hotchkis package make celicas pull like 1.4 on the skidpad?? thats incredible. plus breaks are a must too, because when you hit boost in 1st gear your car will launch forward, and ive had a couple close calls were people have suddenly braked in front of me and I barely had enough time to stop, I have TRD
pads and Brembo rotors and it still locked up on me, I am disatisfied with my stopping power, and I want to upgrade to a bigbrake kit.
But yeah man if your going hard core with the engine you gotta get the rest of your car up to speed and those kits sound like the way to do it
