I am having the downpipe custom made later but will a 3rd gen exhaust manifold bolt on to an s4 engine? I guess I am just asking if the studs are in the same place.

 

Yes, all 13B engines have the same 4 studs and bolt pattern.

 

Will the turbo hit the LIM or shock tower since its designed for a 3rd gen? Or is there to little information?

 

There are pics of a SSAC FD manifold on an FC on the second to last pg of this thread:

I think the clearance of the LIM depends on the a/r of the turbine, <.90 okay maybe. You could buy a 3/8" steel flange form racingbeat for $20 to sapce it out from the engine. I think there is plenty of room to clear the shock tower.

No, the 3rd gen SSAuto Crap mani won't fit on a TII engine without modding it (spacing it out) or using a less flowing, only available in open valute (non divided) on-center type turbine housing. Even if you just space it out enough to clear the turbine and downpipe, your turning your lower intake into a inter-heater by having the turbine and dp so darn close to it.
