i want to build a plenun for my original b16 intake manifold but i need to know what kind of aluminun to use!

 

5052 or 6061, i suppose a high temper is not that important since its going to get welded.

 

thanks man!! what about thikness?

 

1/8" would be a good start.
Easy to weld, thick enough for n/a easily, and low boost.

 

sounds good!!! so you say ill need something thiker for high boost

 

what are u looking on to tap in vacuum lines etc.?
1/8 is thin enough

 

Ive only build 2 and both where .125" and used for low boost but 1/4" should be enough for high boost, hopefully someone with more experience/knowledge can chime in.
