Not sure if this would work, but its got to be there for a reason. If you look at the sleeves for the auxiliary ports on the Renesis you will see that they are shaped quite differently from the sleeves of previous 6-port engines. The port shape into the cylinder is approximately the same, but the sleeve is quite different. I assume that this creates less turbulence and increases volumetric efficiency. It could easily be incorported into the sleeves of any 6-port engine.

nice pic, what are those things sticking out of the primary ports?

they are air bleeds, i think its to try and speed up air on the long side of the port?

Very nice. Are those aux port sleeves turned from outside with no rod down the center?

That renesis intake needs to be retrofitted to an FC3S sixport.



It's not a bolt on but it could be done.

Can you get some more detailed pictures?

I saved that one from a website that I found. I think it was a translated japanese site that called them renesis spy shots. It had a bunch of pictures with a spy by spy theme, but I dont think there were many other good ones. Ill try and look for the site.

The renn's 6 ports are a much larger diameter then the FC's

Finding an EMs solution to run those might be the real difficult part... Don't know it it would be worth it over running TII plates twin TB's with a decent ems...Still fun to ponder though..
