Are there any snags with peripheral ported single turbo FD3S engines? If
this is swaying too far from the lists purpose maybe we could take this
to e-mail? Interested in circuit race usage, a PP would fit the bill i
think, it's just that i have never read of PP engine that's
turbocharged, only NA ones. Thanks.
