what im talking about is pure hardware only no ecus, exhaust, nothing but bare engine this is what they come out fresh from the development rooms. which explains why the power output is low. sorry if i've missed that out. but thats the point i forgot to mention. i was hoping to share the true factory form of the 2ZZGE. power purely at hardware (engine) nothing else. like what the papers say its noodles and if you want more add seasoning. your car is obviously 153 after adding the flavour :P the 141 toyota aus (11kw increase from SAE papers) would be due to the exhaust (even on the toyota website it states why it has 1kw more then the celica due the exhaust being longer and able to make more power) intake setup, fuel. This is when the power begins to increase when more stuff is added. so yeah my post above was about the power outputs. in factory form its around the 130kw region. Fuel grades, exhaust setups, materials, engine load, wheel size, tyre pressure, ecu maps, intake setup, ambient temp, engine/water temps. etc will effect the final power output. its toyotas job to select parts like we do to make them better/faster. americans usualy have lower power due to the lower qaulity of fuel they have there.
