It’s not easy but the pontential is enormous and all the work has been done by dozens if not hundreds of people, the parts, knowledge, and aftermarket support is there. Front wheel drive, rear wheel drive, all wheel drive, turbo, all motor, supercharged, nitromethane... It’s all been done before.
Don’t get me wrong, the Ecotec is a great engine platform and probably a simpler swap. But If they want the best of the best, the K20/24 is a modern monster and in a whole different league. Boost it, and the sky is the limit.
