I've seen that video before and it looks wicked... No idea how it was built though. I don't think the owner is on here.

It would be awesome to build a 4 rotor out of 2 13b's with the 13b rear iron for engine mounting purposes.

I wonder what center iron they are using?.. and what e-shaft.

Yea there has been at least 3 threads on this before, but oh well. I dont believe we ever got an answer on exactly how it was built.

i cant see how this guy could have coupling the eccentrics together. if one engine makes slightly more torque than the other it would snap what ever he rigged together.

unless he actually used a real 4 rotor eccentric. In that case i can`t see why he would pay over 6K for an eccentric and cheap out of the rest of the build.

apparently the guy also has a N/A 3-rotor that is MAD GHETTO. (or it might be a friend's car).

i saw a video of the 3-rotor...it doesnt even have a N/A exhaust manifold! the dude just pulled off the chra's on the stock 3-rotor twins and capped them off somehow.

here's the other vid:

Why is that? Seems to me they obviously wanted a 3rotor really badly and found a way to get it running as cheaply and as quickly as possible. Nothing wrong with that IMO. Most don't get the fact that he's won half the battle do ing the swap and getting it to run in the 1st place. They can upgrade the set-up later as their budge allows.


I think the 4rotor is legit but can't be sure. The exhaust (though very quiet) has that familiar tone.
