Here a 250 from a n "Omega" is compared to one from the silverado. Aparantly the omega engine has 168HP while the silverado engine has 138HP but it has more torque at very low revolutions..

"They see the Numbers:

- Omega: 168cv and 29.1Kgf the 4500 RPM
- Silverado: 138cv and 30.7Kgf the 2500 RPM"

Also from what I could understand, both have sequential multipint injection, distributorless ignition and individual individual intake runners!!!

"The engine of 4,1 liters drift of the used one per decades in the Opal, but suffered significant alterations in the system from management, with injection sequential multipoint Bosch Motronic and direct ignition without deliverer headstock, with geminados individual ducts of admission instead of; command of valves, with bigger duration and crossing; pistons, lighter and with forged knuckles; springs and rods of valve, more resistant."

Anybody interested in importing new parts for our 250s??

I'm gonna be saving up some money to go to festival in brasil (birthplace of thongs, btw) and come back with a new 250 from an omega!!
