Default Need help with 80mm BBK

I bought a 80mm BBK from someone here on CF who claimed about him taking it off a 2003 Z06.


Now I have a BBK without the spacers that according to BBK's website are required for installation.

can someone that have a one help me here ?

I would like to get this installed.

I didn't know you had one. I will have to take a look at it.

the spacer provides a smooth transition from the 80 mm tb to the 78 mm opening of the Z06 intake mani.

It is not necessary but it won't be a perfectly smooth transition from the tb to the mani.

Another option is to have your intake mani opening bored to 80 mm. Any machine shop should be able to do it for almost nothing.

good luck

I'm 99% sure it's 78mm and that's why everyone gets their throttle bodies ported to 78mm, but I've never personally miked one out so I cant go 100%
