GTS is the american marketing name for a celica with the VVTL-i engine. T-Sport is the european name for the same thing. The very first of the GTS/T-sport models were 192HP at the crankm however this was only for the first 500 cars and thay were all japanese models. The rest were 180hp at the crank. BTW this is the result of research and not gospel. I have one of the first Jap models and its at 209HP at the wheels at the mo.
