We plan to offer EF1/EF2/EF3 upgrades to the best of my knowledge, however, we haven't been able to source cores to offer these as new units as of yet. As Nick outlined the EF1 is a compressor wheel upgrade only (larger than a 16g though Aaron), the EF2 is the same compressor wheel with a turbine wheel upgrade, and the EF3 includes even larger compressor and turbine wheels. The EF2 is a 450+whp turbo for Evo platforms, but I wouldn't be so quick to say that it would perform at that same level with DSM housings (although the EF1 has been performing very well).
