what is the audm dc2r tb size?

[BlitZ]

is it 62mm?


i have read the JDM is 65mm? is this correct?

has anymore bored it out and what were the results (has been discussed but a mixed bag of results)


And lets not talk about taper bore..



And last but not least.. where can i buy a larger butterfly from?

[tinkerbell]

it is 62mm ID

[tinkerbell]

i got Corey from, http://www.katicore.com.au/ to do m VTiR oen from 60mm to 63mm with a taper bore...

he will do you a TB plate, BUT surprise surprise - he will HAVE to match it to the TB opening...

[tinkerbell]

results obviously depend on other modifications.

in my case, i obviously gained a fair bit...

[BlitZ]

tink.. do u know what it was tappered out to..

I presume it is now 63mm at the butterfly and ~65 at the outter lip? this spec would be very very close to the ITR one

[tinkerbell]

no, i did not measure it... yes, 63mm at butterfly...

Lol i hope this doesnt turn into that heated arguement on power gains from bored out TB like over at Ozhonda hey Dave =P

AUSSIE AND JDM same 62mm.

Sell your stock one for $200. Buy an aftermarket throttle body 65mm for $285.
