It looks like these cars will be difficult to do a really well designed turbo setup on.
It seems all the setups that run a single turbo up above pan level (i.e. in front of the engine) have really terrible exhaust routing and small downpipes. Not to mention a lot of the charge piping having to be really close to the turbo.
The other way Ive seen it donw is dual down by the transmission. Which although has better routing of exhaust and probably charge piping as well, it has the issue of oil drainage having to use a pump, which Ive never been a fan of without the use of a sump (which I dont think would be possible).
