I dont think its a replacement motor. I just think the omp went out and to go to something more reliable they swapped covers.....hell the throttle body is s5 since its got zip ties holding parts together to make the mechanical OMP work.....S5 air pump and acuators....s5 rats nest and all.....Well ill just gut it and go pre mix. They even used speaker wire to wire up some ground connections........

 

Am I crazy or is this a s4 NA egr?

I hate red neck mechanics wow.......

 

yup

also, the EGR thingmy on top of the centre plate is a give away

you need to remove and blank it,, and fit the more slimline s4T fuel rail to get 13bt manifolds to fit
( provided the turbo LIM is modded for a 6p block )

 

ok so in otherwords I got a s4 with a s5 duck tape omp. That sucks.....

Well on a side note will a fd UIM bolt up to the na 6port lower manifold? (barring minimal modification)

How can I tell if my lower manifold is from a s4 or s5?

My throttle body is going in the trash as a side note.....

 

S4 Lower from a NA Has rods on the Aux ports Looks like you have a S4 block just just my the EGR and Primary fuel rail...

 

Yeah its a s4 block....Now I just need to figure out which LIM I have....

Ill be posting a separate tread for my whole build up....

I think Ill be working on the rear end this weekend but who knows.
