So i just noticed that billet rotary sells a 12a 3 rotor eshaft with counterweighgs for 5000$. Strangely enough that is roughly the cost of a turbo, auto counterweight, and other turbo related parts. What mods are required. water pump, studs, oil pump, intake manifold etc? I realize it would end up more expensive (maybe) but im willing to play ball, I just need to know what it takes.

Edit: these cranks take roller center bearings, how will that effect longevity on the street.

 

Not 100% sure what your question is around what mods are required...

But from someone that has a 26b, here are some other cost that i would consider if you are thinking about putting in a custom 3 rotor in a vehicle

• who would build the engine and tune the car
• custom oil pan, lines and cooler
• custom engine mount
• custom headers
• custom intake
• ECU, wiring harness, sensors
• radiator, fan
• battery relocation
• Upgraded transmission, which mean custom mounts and driveshaft
• Custom exhaust
• Now that you have more power, you will want to have good wheels, tires and brakes if you don't already

All this stuff adds up quick then you have to find a reputable shop to build in a timely manner if you don't have the know how.

 

I kinda want to know want to know what needs done to the engine in order to make it function well.
