just installed 1zz throttle body - Toyota Yaris Forums

2009Toyotoad · 07-08-2015, 12:31 PM

Forgive me in advance and tis are newbie questions, but I'm confused. If the route to forced induction via turbocharging calls for bigger injectors and a bigger TB, but invader166 is indicating than the bigger TB only benefits top rpm performance how is Turbo charging the 1NZ-FE of any benefit on the street where Mid range is used most of the time? I hope I'm not asking a foolish question, but the responses are leading me to the conclusion that turbo charging the engine isn't going to give me more power across the power band, or if it is, a significantly lower compression ratio is needed to achieve that power which will eat up fuel and remove any economy from the vehicle. I'm really confused.
