Ok. I'm sure you have all been through this before, but...

I'm early in the design of a rotary powered single seater. I would like to know the weight (and approx cg) of a late model turbo 13B (was thinking of about '93 or later). This would be motor, manifolds, fuel injection, turbo etc. but without the (water) cooling system as I'm planning on that being in lower rear fuselage.

Gearbox will be Tracy's RD-1B gearbox at this stage. He will probably get his 2.85:1 box out before I am ready to purchase, but I expect the weight will be about the same.

Also similar information for a N/A 20B would be useful.

The weight less intake manifold and exhaust is about 240 pounds with Tracy's
PSRU. The completely dressed CG will be about the intersection of the front
rotor housing and the front end housing. (Rears in the car).
The firewall forward weight including rads and coolant will be around
300 to 320 pounds.
