They are for 3000gt vr4 , will be dyno testing one in the next couple day. Is fabricated from 5052 1/4 PL ,fits a 82.5mm Q45 TB , CFD testing indicate a very evenly air distribution among the runners.

Looks better than any IM I've ever seen for a 3S.

Have you thought about using a non-turbo DOHC intake manifold? There are more of them around, plus you could have the plenum part be a bolt-on affair, rather than welding straight to the runners.

 

nice job...now lets see how much HP it makes over the stock IM

 

Yes I have used them before, there is not much difference in runner diameter so I use whatever I have on hand , plus the real problem on the 3S Manifold is the surge tank huge bottle neck.

looks pretty cool....just one question though, why not do custom runners as well?

 

Yes, this are my ECONO version , I do build them with runners but is more costly.
Im in the works of building one right now I will post pics.
