    57mm TBs

    Is it worth putting 57mm Throttle bodies on a 02 Mille replacing the 51mm? What's the difference in performance? A little or a lot?

    tb mods are only realised accompanied with airbox, exhaust and ecu eprom mods as well, the gain isn't hugely significant but noticeable. Yes CL all GENII tb's are 57 and yep the large angle pipes (IACV system) need blocking off.

    Yes all gen 2 tb's are 57mm and yes both larger pipes, and one of the smaller pipes.

    Tash is sending me Tuono velocity stacks for more midrange as opposed to RSV stacks for more top end rush. Not sure how much of a difference it all makes but a Renegade style airbox, collector mod, Dr Rossi chip and 57mm TBs, it sure isn't going to be slow. Got to get the gearing sorted too. After that Griff can service her in March, check CO2 and set up suspension. Roll on spring and all those R1s who are going to get destroyed in the twisties!

    im guessing the smaller one that you block is the same one that is capped originaly ond the other is for the ppc valve pipe i thought thats what it was just wanted to make sure off someone that knows more about them than me hhaha
