Do Hayabusa bodies take standard bosh injectors?

As subject.

I'm looking to put some Hayabusa throttle bodies onto my tintop (Zetec) and am wondering if they use the normal size bosch style top feed injectors or pico or?

Clearly the fuel rail would need spacing, but if I wasn't going to respace would the bosch's just fit?

They don't quite fit in my gsxr1000 bodies, the nose of the injector is slightly larger than the hole in the body, but it shouldn't be hard to bore it out to the right size. I'm not sure about the fuel rail though, I used the OEM fuel rail when I had my tb's fitted as it was already the right spacing, just needed a couple of brackets to hold it.

Of course, the 'busa might use a totally different type of injector to the lesser gsxr's, in which case i've been no help at all

Why not use the Busa injectors?? I am using GSXR 750 injectors on my 2.0 Zetec and they have capacity to spare.

I could do, but I've literally just installed new injectors which ideally I'd like to keep, given that they are new & flow as new.

But yip, could sell them to pay for a clean.

You can probably make them fit but you'd not have much meat left on the tb's around the base of the injector.

The busa injectors are really rather good and will flow enough juice for 220ish bhp with a sensible duty cycle if you raise the fuel pressure to 55 psi which is well within the injectors range.
