UIM options for 6 port turbo
I was inspired after seeing Aaron Cake reusing the stock 6 port LIM and building a custom UIM, so I'm exploring some options that also reuse the 6 port LIM.
Right now I am running all s4 na intake manifolds, and with the TID and both IC pipes (all 2" dia) on the passenger side, its a little crowded.
My plan is to use a turbo (T2, REW, or RE) UIM and build a runner extension between the UIM and LIM.
Im thinking the easiest route would be to use the T2 UIM as things like the TPS would still be compatible and I think I could still use the stock ECU (Rtek 2.x) whereas if I used the REW UIM it would be a little more difficult than that.
Any thoughts or input would be greatly appreciated.

like the last guy posted, its the LIM that you want and the UIM, but you have to match port. but if your doing that, might as well get a FD LIM and UIM then match port them. i also forgot but you can try to look it up, there was a test on FD intake manifold vs FC T2 intake manifold. there's some ups and down... look into it.

FD LIM is garbage. stay away. the manifold was designed mostly with packaging constraints in mind. they are well known for their assymetric design as well as leading to lean conditions on the rear rotor, which is why FD guys try to get aftermarket LIM's.

Does anyone know if the s4 na LIM runners are equal length (not that they are very long anyway). I seem to recall that the runner to the front secondary port was slightly longer than the rear.
