64mm Throttle Body
64mm
45mm
This is one of the best mod you can do!!!
It's the TB of a Bmw Z3 (Bosch)
I prefer it to throttle controller or new intake manifold...
The car runs like a diesel with 6000 rpm!
The first noticeable increase is the faster revs of the rpm.
I think there is a great increase in torque and hp too...

Throttle Bodies
I was going to see if i could send mine in even though they only do B and K series throttle bodies.
it looks totally stock from the outside and the dealer would never know.

Its the same TB as the US Fits.
Im interested in how the car knows whats going on with a BMW TB on the car?
Unless its a BMW butterfly in a Fit OEM TB.
I have a spare TB from what I ported my OEM. Hehh...
Ryan, I was going to send mine to that guy. He said he could do it.
I think that was the guy. Hes all over Honda-Tech?
Check the TB Kelsey. Its got the DBW plug.

It's easier than you think...
same plug;
same bolts.
These trhottle bodies are made by Bosch, so you don't have to be worried about nothing: they work in the same way!
The only thing you have to build is a gasket between intake manifold and new throttle body (I used a can of coke!!!! It was the fist thing I founded in my garage) and a conic joint inside new TB from 64mm to 45mm (I used my wife's plastic breadbord).
I'll post other pictures tomorrow
PS I forgot to say that this TB hasn't water passages and that I'm not going to do dyno test before finishing all my mods!!

But damn the car pulled nice. I barely ported it too.
I bought an OEM for cheap. (I think theyre $400)
I tried to take it into Honda saying the idle got high. *LAUGHS!*
They inspected it for an hour and didnt even find out it was ported. They noticed my coolant lines being bypassed and blamed it on that.
And yes, as asked above.... What year BMW? Im so doing this.
Theres no Check Engine Lights? Everythings fine. Car idles and drives the same?

Porting the OEm TB without getting a larger butterfly will cause high idle problems. 
....
64mm is great provided the hole in the plenum is that large otherwise you'll be adding som major turbulance to the scene... if the Plenum is lrger than the butterfly then rock on!!!!!

I have a question about the dbw. I remember reading somewhere about the k24 in tsx's that where being moded and had the dbw disabled and the car worked fine. I'll try to dig up the article, but can't the dbw just be bypassed and work like a "normal" TB?
