No additional info to add (I think this is a great idea BTW). I've lots of questions instead , the answers of which might be useful to keep with the TB info.

I've got TB's from a GSXR600:

There doesn't seem to be anyplace to mount a fuel pressure regulator on the fuel rail. Where is it normally on these things?

The TB appears to have a built in MAP sensor, plumbed to all 4 TB's - is that what it is?

The ECU controls the secondaries, so that big block on the side is a stepper motor of some kind? What's this for, higher air speed for low end torque? Any idea how the ECU controls it? Analog, digital, what engine conditions?

There doesn't seem to be anyplace to mount a fuel pressure regulator on the fuel rail. Where is it normally on these things?

Don´t know but anywhere between the filter and the rail will work but I would modify the original rail for fuel in one end and fuel out in the other, blank of the original inlet or use it for ex. pressure guage. This would cool the injectors. I have done it for a friend and here is some pictures of it.

Yes, it´s the Suzuki MAP.

Not a stepper motor, it´s only a magnet inside with a coil on the outside.
It´s for better throttle response in low revs, Reverse polarity makes the magnet open or close the butterflies and a secondary TPS for feedback so I would call it Analog. IIRC it´s controlled by a tabel like the injectors, can´t find the link about that.

Found the link on the sec. throttles:

Great Sticky! Thanks guys... i have a couple of additions....

Fuel Rail: Alu casted, 1 per injector, joined by solid fuel lines

Comes with MAP, fuel regulator, TPS.

Has a manual choke mechanism synchronized to both TBs. Not sure how it works - fast idle bleed perhaps? Sure looks like it.
Separated, the TB's can be mounted 200mm on center parallel in their original orientation.
Flip the TB's in 90 degrees so the linkages are touching, they could be 130mm c/c.

<edited using sportbikeryder's info - thanks!>

according to test results listed at http://p090.ezboard.com/fazbiketechfrm1 ... D=33.topic
, Honda 1100XX injectors are ~335cc/min @ 43 psi, 100%

Thanks Sportbikeryder, I have seen that post before but after much searching never found it again.

Just took some measurements on my TB's.

03' GSXR 1000:

-Tapers from 50mmID to 42mm ID.
-OD at inlet end is 53mm.
-90mm overall length, +/- 2mm.

Hope that helps.
