Setting up MS2 sequential fuel is pretty easy, and not expensive.
(JBPerf 4 channel board, 5v>1K pullups on the coil drivers and use LS2 or IGN1A coils, or dirive direct w/o the pullups.)
I believe Evos are batch fire, but I'm not 100% certain. I know they are wasted spark in stock configuration.

Dual TB with Intercoolers

I too have done this on a Type-I for Jay Manino, about twenty years ago.

The result was a great improvement in throttle response/lag reduction.

Another Type-I with the same style intake was fabricated in a way to include the intercooler
between the air door and the runner bell mouth.
