I managed to get a set of TBs from a GSXR 1000. I heard however that 1000 TBs are too big for use on a Vauxhall 16V. Is this the case?

A 20XE running throttle bodies should be producing simmilar or more power than a GSXR1000 so the TB's should be pretty much the right size size IMO.

IIRC, they're the same size as 750 bodies....so are probably OK, but slightly oversized for a standard engine...but that's only likely to really affect fuel efficiency...

I'm running 750 bodies (48mm tapering to 42mm) on my 2 litre zetec....and they're fine....

Yep I concur they are idetical to 750s depending on year I think the injector rates are actually identical too.

im running them on my Vx redtop and so far seem fine
