The GTS was a North American-only version powered by the same 5SFE as the GT, just with more options -- think GT made to look like an All-trac.

The 3SGE was used on GTi and GTr as well as SSII (I or II, can never remember) cars produced for Europe, South America and Asia.

The GT and GTS were both ST184/ST204 chassis codes, the ST182/ST202 came with the 3SGE.

He's asking about a 4th gen GTS, which did come with a 3sge. Sorry but not sure what octane it uses.

Do the US market Celica's have lower compression than JDM/Europe/Asia-Pacific markets? All the info from Toyota that I have recommends using the highest octane available.
My RC even has the original 'fill only with 100 octane' sticker on the fuel door from Japan....

From the back cover of my 88GTS owner's manual.

3SFE (ST, GT) and 3SGE (GTS): 87 octane or higher recommended.
3SGTE (Alltrac turbo): 91 octane or higher. Only use 89 or lower when 91 not available and for as short a period of time as possible.

I think the compression is the same but the tune is different. It probably allows for more aggressive timing.

North America is a little different from many other areas of the world in whether we use the octane rating versus octane research number for gas.

Japan also has much higher octane levels available at the pump due to their different engines. Got to remember, they switched to unleaded gas (which means octane is required) years before most of the industrialized world.
