I Just Got A '92 Celica St And I Was Wondering What Can I Do For More Speed???

Cold air intakes and exhausts are always a nice start. More air flow usually equals more speed.

To be brutally honest, the ST and its 1.6 were not built for any kind of speed whatsoever, and short of a bottle or forced induction, you won't get it.

That being said, the GT and GT-S with the 5SFE weren't built for speed either.

yeah thats what i found out so im going to get a gt-4
