|Just having manifolds available to install the latest turbos is good enough. V Band downpipes are easy enough to make.
with space behind the engine/trans to tie in both banks we could even use bigger turbos than GTX3067. I have a drawing somewhere where I was going to do this myself, similar to the Z31 Turbo but both banks feeding the other side. Using a "ghost" runner from one manifold going to the other side so instead of 3 into v band flange there would be 4 primaries into v band.
So there would be 3 primaries from that bank feeding the turbo then the 4th primary from the opposite bank.
