What is the difference between S4 TII and S5 TII LIM ?, How do i tell them apart?





Thanks, Brian

 

the s5 has 2 vacuum nipples pointing horizontally at each other between the secondary injector holes.

 

Sounds like my EX wife!

 

no subzero start assist either

 

The egr passages are in different places. You have to see the engine mounting face to determine this. The S4 has it's passages in the center under the primary ports and the S5's have them on the outsides under the secondary ports.

Keep in mind that while some people here claim one flows better than the other, this isn't the case. From a flow standpoint, they are identical.

 

are they interchangeable?
thanks

 

I believe they both fit the block but the runners are different where they meet the uim.

 

The runners pysically line up just fine. The rear most bolt hole is moved over though. The others work. You can modify that bolt hole to work.

 

ok cool, i really just want ot run fd uim, and the adapters are only for s5 lim

 

Im doing the same thing, just bought all the manifolds, spacer and gaskets and waiting for them to get here.
