I would think building a 1.6L with pistons, rods, studs, and upgraded turbo would be easier than a swap. The 1.6L tork has is starting at 344whp and they are starting to tune now.
LS4 is a fwd designated engine that the impala ss used.Someone throw in a Northstar!!! Keep it FWD lol
How much power would you be going to? I think Tork said 400 ft lbs is what the tranny in manual is rated to but will depend on the half shafts.That is also my concern. The 2.0 theta from the 2016 Forte ex has identical mounts. The wiring and Forte ecu is not an issue for me and would be well worth it to have the 2.0 built and boosted (cams are also available). Transmission is going to be a limitation though.

22.5" vs 21.75" is negligible vs dealing with the height and width issues of a DOHC engine. Also dealing with the intake gasket issues inherent to a dohc chevy design is not something I'd desire.The 4.6L Northstar LC3 will likely fit nicer between the frame rails than the 5.3L LS4
