Does it? Just curious to know if an FD LIM will fit onto an S4 T2.

 

Not without a custom spacer .

 

^ You are thinking of the UIM. The FD LIM won't work because the secondary ports are significantly bigger on the REW. Even the s5 T2 LIM doesn't work well on s4 irons because the s5 port runners are larger on both the manifold side and on the irons. I compared them myself and ended up swapping to an s5 LIM when I went with the s5 irons for my rebuild. Besides, the FD LIM has uneven length runners due to fitment constraints from the twin turbos.
