I am currently doing a 6 port turbo and I am unsure of what intake manifold I have can anyone tell me what the differences are between the S4 and S5 TII intake manifolds is. My second question is what primary fuel rail do I use, the N/A or TII?

They look like s5 but the tb looks s4 . Hard to tell with the tps missing . I've got a build thread going on my s4 6 port turbo with a holset hx52 and streetported . Check it out if you got time . Lot of info on here just got to site the forum in Google to get better searches . Good luck with the build .and if I'm not mistaken I used my na prime rail and s4 t2 sec rail

I disagree, that LIM looks like a JDM S4 to me. Note the brake booster hardline/banjo bolt on the runner and the lack of secondary air bleed nipples on the runners.

You sir are right about s4 , that is my mistake . I have s4 jdm manifold from what I know . Usdm had egr am I right on the mani ? Here's two pics of mine with s5 t2 tb I just installied for my haltech . I just finish redoing the gaskets on my friends s5 vert with s5 t2 swap and should of caught my mistake above befor I even posted .

Ok so the lower intake manifold is s4 JDM and im assuming the upper intake manifold is S4 USDM does the S5 upper intake manifold not line up properly i've seen the gaskets look differently. Ive been talking to FFE about their fuel rails and they cant tell me if the tubo II fuel rail will fit the NA center iron they said it should can anyone confirm if they have done this before?

its an S4 JDM lower, and a US S4 upper.

the fuel rails all bolt to the block the same, so the FFE rail will fit.

i think the NA rail will fit the T2 also, but you might want to mock it up first, its a tight enough fit that there is a bump in the upper intake to clear it
