Hi, i read some where on this bord that jap celicas have 10 extra hp cuz of the 100 octane gas the rune and that the cam gers are rotated by few degrees , if i run 100 octane and rotate the cam gers will i get same gaings ?

Japanese Celica's are rated at 190PS (Power Stroke) which is about 188Hp at the flywheel. You do not nead cam gears on the inlet cam because of the VVTL-i engine design/electonics. This means the inlet cam is always automatically adjusting within a certain timing range,which is determined by the ecu instructions dpending on your driving mood.

I reckon the 8Hp difference has to do more with ecu settings for more stringent emissions laws/rules for US delivered automobiles. Because my Celica is rated at 140KW (kilowatts) stock, which is 188HP and I live in Australia.

Bottomline, get yourself a Apex'i S-AFC or some or similar fuel piggy back computer OR replace the ecu if you have bigger plans. Then have it installed and tuned on a dyno with a good wide band oxygen sensor, with the highest octane fuel in your local area that is readily available.
