I'm running what I think are GSXR xyz throttle bodies on my Duratec. Due to an unfortunate incident, I need to replace/ upgrade.
1. Is there any easy way to identify what I have?
2. Is any of the range better than the rest - i.e for more power should I try to get hold of GSXR1000's etc etc
Send me a pic Russ and Iíll try and ID them
I've got K1 GSXR750 itbs on my car. They are the same nominal size as GSXR1000, 42mm.
They are actually 51mm at the filter end tapering to 42mm at the butterfly. The manifold end is 42mm.
I've also got a set of GSXR1300 Hayabusa bodies ready to replace them. Nominally 46mm.
However, they are 51mm at the filter end tapering to 46mm at the butterfly then tapering to 42mm at the manifold, so they are only bigger at the butterfly. I have bored the 42mm part to 45mm.
The throttle quadrant is at the opposite end on the 1300 type.
Post a pic on here to get a positive ID.
