I am getting ready to swap out the engine in my 97 for a 2001 dek. I have read through several threads but haven't found what I am looking for. Which throttle body and iavc combination should I go with if I am swapping a complete engine. I know you can do the 5th gen tb and iavc, and 5th tb with 4th gen iavc, and the path finder tb is also an option. There may be other combinations also that I am not aware of. Will the 4th gen tb and iavc work with a 5th gen motor?

 

Whatever one u decide replace the iac valve first and do the relearn.

 

I currently have the 5th gen TB with 4th gen IACV and it works great.

 

Easiest would be 4th gen tb and and.iacv both with block off plates. Pathfinder tb is an option like u said but it would be good to port match the upper manifold to take advantage of the extra size of tb

 

Is there an advantage/disadvantage of using the 4th gen iavc over the 5th gen. iavc?

 

The thing about that is you need an adaptor plate for the 4th gen tb. Cost wise its probably similar to the 5th gen block off plate, but IMO, the 5th gen TB with a relocated 4th gen IACV looks better.
