i was wondering if a 20b 3 rotar engine out of a cosmo would fit in my 10 AE?

 

It can fit. It has been done several times. For more information on this subject please refer to the 20B forum of this site or search for the information. Its not an easy modification, nor is it cheap, since teh core itself can run upwards of 4k for a real 20b from japan.

 

Where do I find an imitation 20B? I don't want to pay the cost of a genuine real 20B.

 

lol....imitations are esentially, from what ive noticed that is, a custom 2pc eccentric shaft, housing of choice, and rotors of choice that go with said housings. All that would in theory be needed is a custom intake, oil pan and exhaust mani.
