David,
I have two 20Bs.
The one pictured is a number series that I'm planning to go NA with with S5 high compression rotors (like Gordon's) and 13b housings. The housing and everything looks really good (very low miles) except one rotor and housing...
The other one is D series 20B which will be built and cranked on a table by end of this month. That one will be a turbo'd 3 rotor. It will be ported (bit bigger than stock) with exhaust sleeves taken out for better flow. I'll have videos of the engine cranked on a table when its ready
