Size of EK4 VtiR throttle body?

**jords** · 10-11-2004 03:21 PM

Just wondering if anyone knows the size of the B16A VtiR throttle body?
Is it larger than D16Y Vti throttle body?

yes, but i *think* it is 60mm vs 58mm in the D16...

teh early JDM B16A's were only 58mm too...

(can someone confirm EK VTiR is 60mm?)

i think all b16a's were 58mm tb...

58mm.......

you may look for JDM ITR 98 spec throttle body which is 67mm but you could bore it to 70mm

i think its 58mm.
and the JDM ITR is 67mm

no, only 1st gens were 58mm, the B16A2/3 are 60mm (i have just searched Honda-tech to confirm

)

also - 60mm TB was used on B16B, B18C and H22A (except B18CR = 62mm)

BTW - i also doubt that hte JDM ITR TB is 67mm

here is a pic - measure it

This is my old B16A2 - AUDM spec. maybe it is 60mm

ok
looks 67mm to me.

**tinkerbell** · 10-11-2004 06:18 PM

hmmm, looks to me like it could have been bored out

nice one

stock = 62mm

EDIT

sorry, yes - you ARE actually measuring the wrong side - take it off and measure the side that faces the intake manifold.

apparantly the ITR tb is tapered:
