Thanks for the tips. I thought I better read up on him before I
contact his mechanic Gary (I will talk to him first, then attempt
Barney).



On the FI system, yeah, no way I'd attempt any mechanical scheme.
They all sound exotic and unreliable. Expensive also. Megasquirt
and electronic.

I have to find more books on turbo-engine design & build. I've got
the MacInnes book (thanks John!), it's somewhat dated but it's got
the math, but it's light on per-case data, the sort of
application-specific rule-of-thumb I like to make the numbers make
sense. There's no empirical data in it on general usage patterns,
longevity, etc.

With this weird block, crank and heads I would build a motor very
differently than if I were to put a turbo on my stock 258, for
example, which is the line of thinking I've always followed.

For the stock 258, I'd never rev it past 4000. A small A/R turbo
to get boost at low speeds and have losses pile up at 4000 and
beyond.

With this Navarro block, with it's crazy-huge oiling and balance
etc, I'm sure 6000 rpm is no big deal, so maybe a more streetable
idea is, a big A/R with low restriction such that there's little
boost below 3000 rpm, and LOTS at 5000 - 6000, wold get me a
drivable motor with crazy HP should I decide to rev it.
