Has anybody or does anybody know someone who has used a two rotor Cosmo motor in a third gen?

If so, where did you/they get the rear housing to mate up to a manual transmission?

Did you/they cut down the Cosmo intake manifold so it would fit under the stock hood?

Is the two rotor Cosmo just a three rotor Cosmo with one less rotor?

 

That would be a backwards step The 3rd gen engine is better than the 2 rotor Cosmo and yes, the 2 rotor cosmo is one rotor shy of a three rotor The Cosmo is a mix of Series 5 and Series 6 engines.

 

personally i dont think that its a backwards step, the cosmo motor has way bigger intake and intake ports than the rx7 motor but the turbos are smaller than the rx7
