In terms of weight yes it will be better than 3SFe but have to do a bit more work due to FWD configuration.
But the Torque 3SFe have its own feeling .
Better go for a 7A-FE from a AE-112 rolla instead of 4A as it have almost the same weight but more recent and good acceleration.
But have to find a good T-50 tranny to match with that motor .
All depends on how much you wanna invest .
