Now a 3 rotor has how much of a horsepower/displacement gain over the original. Are you turboing or naturally aspirated

3 rotor increases displacement by another 33% (1.3 to 2.0). The engine 3 rotor/20B came from a car called Eunos Cosmo (I posted pic of it on post #1), a luxury brand of Mazda (like Lexus or Acura). Cosmo 20B was the most expensive Mazda in the history of Mazda.. back when (1990-1995), it was sold for over 60K USD. It was also first in automotive world for 3 rotor engine, central touch screen navi/climate control, seq. twin turbo, etc.
Regarding power, this is the engine that won twice in Daytona 24hr (same short block with different compression rotors) and NHRA 3 rotor drag cars. HP potential is over 1000 and because of its displacement you gain quite a bit of torque.
I'll be doing force induction...
Update
December 6th, 2011 I got a call from my fabricator and he said he checked on the pricing for the Stainless 321 and going to order some for the new manifold set up. This means, my old SS 321 manifold with Racing Beat header flange is for sale!!! If you are interested let me know
Here are pics of my old flange set up!
Here are the pics and placement of the turbo.. Turbonetic T76 BB.
In the car with Hinson 20B /Pettit Subframe with this manifold with Garret T76 with T4 Undivided flange.
