probably not, they built the same engine both ways, same hp on both. (NF
and NG, 130 in US)

big old hole in the head, continuous with the IM air space (like a goofy
"8" shape, sort of).

the injector is mounted in the manifold but sticks into the head a bit I
think.

they are barely further away from the valve, if at all.
