I've heard of a 4 rotor 26b Le mans race car rumble up close many years back. I can only imagine what this Mazda RX 4, shoehorned with a custom 6 rotor engine would sound like in real life. Since 2 rotor engines are considered equivalent to 6 cylinder engines, this would make the 6 rotor engine equivalent to 18 cylinders. Overkill? I think not.
Pick this up from a local chap awhile back. Parts like these are very rare to see nowadays, so I jumped at the chance at getting it. Kinda like chicks with their purses, obtaining old HKS parts seems to be my vice. But it'd be a nice addition to the old twin tip exhaust, the original HKS sport exhaust.
Be very wary of shops that are manned by rookies who know more about jdm style than working on cars. As this unfortunate owner of a 20v 4ag who picked up this engine at a shop in San Diego. It was sold to him as turn key setup for the AE86. It had issues here in there, but I think this takes the cake. Hopefully a little piece of silicon didn't break off a plug a water passage. Instead of getting done sooner it's getting done later. Damn rooks.
