I was going to build a 4 port NA engine but I like the idea of a turbo for
increased VE and altitude performance.  What would be the difference (# of

does the turbo use?

Very good question. I don't know but I'll bet it will be some. PL

The turbo motor should definitely have better BSFC if designed for 200 hp.
The reason is because the NA motor will have to have tuned manifolds and
overlap to allow scavenging of the clearance volume.  This usually results
in some mixture being wasted in the scavenging event.  Also, the turbo
motor can make the power at a lower RPM, if desired, which always yields
better fuel economy all else equal. JS

I like the manifold (to bolt the turbo onto the engine)
you guys came up with.  If I go with the turbo I would use one.

I'll add youto the "interested list" JS
