The SVT TB IS a 3L TB. Just look at the back side of a SVT TB and you will see "3.0" stamped on it.
The difference though with the taurus TB is that we don't use the rectangular chnnel along the outside of te TB for diverting air around the butterfly to control idle.
So in short, you don't really want to use a Taurus TB on your SVT UIM. Either use our exisating SVT TBor you can go a step up to a 65mmGT Mustnag TB (from years 96-2000), but only if you have done a LOT of mods to support it, otherwise you will lose perfromance!
