The problem with twin sequential turbos is that they peak to fast on the powerband and leave no room for spread.

If you consider doing a twin non-sequential turbo set up, a 2.0l 4 cylinder doesn't produce enough exhaust to spin a sized turbo efficiently. Resulting in retarded lag. Even more so on 2 banks 2 per cylinder like the EJ.

Sure you can put two turbos a 2.0 boxer engine...but a single turbo of any range will yeild better results.

On top of that, LOCATION LOCATION LOCATION..there just might not be enough room for a twin turbo and pluming in the FRS or BRZ.

There are way to many issues besides compression that needs to be addressed before we can even consider an efficient twin turbo setup on the FA20.

So again...short answer...no.
