Well if you look at any Celica GTS or corolla XRS or any right up on them, even looking at the Tachometer, it shows that Redline is Over 8,000RPM. Ibelieve it's someting like 8,125 or 8,250. The corolla XRS has the same motor as in the Celica GTS except that instead of 180 HP it's detuned to 170, well actually 165 with the new Standard they use to mesure horespower. Also if you look at a Corollar brochure online or at the dealer you will see that max HP is attained at 7,600 RPM. Fidgets, you being the administrator should know that!
