My dream is a VW T3/Vanagon syncro with a Subaru engine powering the rear wheels and an electric motor driving the front diff. You could have around 600hp in an AWD van
I've also always liked the idea of a hybrid Baja, the main issue being there's a lot of fabrication to make the front drive train work. Starting with a Porsche 964 could actually prove cheaper
And I've always loved the idea of owning a rally prepped Porsche.
