I have a Lanier Ultimate pitts with a Fuji Bt 32 gas engine. This engine is 4lbs and my all up flying weight is 14lbs. This is not the best preforming engine for this plane but it is cheap to fly, and power is reasonable. Weight is an issue though, and it's wing loading is a bit high for this size of plane. It flys OK but not as light as I was hoping. Lose power and it drops fast. Landing speed is a little high but acceptable and it has no bad habits or stalls. It just sinks without air speed.

I think the Saito 180 would be great in this setup if you don't mind the cost of glow. I love the 4 stroke sound!!!!! It would easly come out at 11 to 12 pounds with this engine. The Saito 200 may be heavy, what does that weigh? However no more than my Fuji I am sure.

The width of the cowl at about mid point is 7 3/4 inches.

When I built mine I put the elevator servos in the tail to offset the weight of the engine. This worked out very well. I also lowered the gear mounting plate as it sits very high up in the fuselage. This way the bottom wing is not so close to the ground and I think it looks better.

If I was going to do it again I would go with the Saito 180, or a larger 2 stroke like the OS 160.
