1ZZ throttle - Not Optimized Yet!

Otherwise, it's just bottle necking the airflow.

People who have done the throttle body mod report more power. Port matching would do even more.

Frown, I'm not saying I won't do it, but it will be dependent on interest, how many people want to go the whole way with intake mani + larger TB.

I would be interested, already planning on swapping the throttle body as my next project. I don't know how much something like an intake manifold costs, but it sounds useful.

I've swapped mine, Garm, but I'll go with whatever you produce and mod it if necessary.

Thanks for picking the ball back up on this. I think it will make significant gains.

Yeah, well the "butt dyno"is a bit subjective until a real dyno run is done. Throttle response is one thing ...
