VR4 throttle body size

[iluszn]

All

have done some research but can't seem to find what the internal butterfly diameter is.

I have been offered a 63mm internal VR4 throttle but if factory is close then i dont want to change it for no real gain.

Ill have a quick skim through the manuals aswell but thought maybe someone might already know or have a factory vr4 one lying around to measure.

cheers

Pretty close to 63mm stock I think.
I know that on throttlebodys.com steve machines them out to 63 and does a halfshaft mod on them.

just checked the site.. doesnt note the original size before bore..

I'm pretty sure it's between 60 and 63mm standard.

 

[iluszn]

so going to 63mm wont make much of a difference.. hrmmm

 

[brisvr4]

It doesn't seem that much of a difference until you take into account the total increase in surface area.( stolen shamlessly from galantvr4.org
:lol: )

60mm throttle body..

why upgrade when you can make 300kw on a 60mm throttle body?
