How hard is it do do this to a 1.3sr inlet manifold?

[Snowface]

Its been machined i think. Where can i get this done? What sorta places do it and also any idea on price?

I think it improves the fuel flow quite a lot so i've heard.

in particular that is rgv_stu manifold, he will post up how he did that im sure

it is easy enough to do if u know how to use a milling machine.

i did my old one and it was sound.

[rgv_stu]

bloody ell , thats my pic / old manifold

i did that with a drill and a burr

you cant go too mad with it otherwise you run out of gasket area

[Snowface]

yeah, i was searching through and found it. Whats a bur exactly? is it just a grinding atachment or more like a sander? You did this your self then stu? how long did it take to do and is it hard to do?

[rgv_stu]

yes its one of many i did. this one is now on will/novanutters car
the burr is a grinding bit
takes about 30mins to do properly, depends how course your burr is

dont try and do it on the engine cus there is loads of material to take out and it wont make it run too healthy , so the maniflod will need to come off

[Snowface]

have you got a picture of the bur you use? i'm not sure what one looks like.
