Renesis aux. port sleeves in an FC N/A?
 
I was thinking that the Renesis aux. port sleeves have probably been redesigned to flow better than the sleeves from FC N/As. Does anyone know if maybe they would fit in a 13B 6-port?

It's a shot in the dark, but maybe it could happen. Yeah, I know about Pineapple sleeve inserts, but I wouldn't want to risk the inserts falling into my engine for ~5 HP.

Also, I have no idea how much a Renesis aux. port sleeve would cost. But, I would imagine not that expensive since they are currently being manufactured.

What do you think?

It isn't a "risk" at all... there's no reason they should fall in if they were installed properly... if in doubt just ship them to pineapple when you order the sleeves, they'll ship them back to you with them installed for free.

Otherwise, I don't know.

U could just buy the pinapple sleeves for the n/a fc. Probably cheaper than the renesis sleeves.

The Renesis sleeves won't work. The 2nd gen sleeves are turned by a rod running through the airstream. The Renesis doesn't have any intrusive rods. They are actuated from the perimeter through a gear system on the lower intake manifold. You'd need to integrate this gear and electric motor system. Unfortunately it is built in to the Renesis intake manifold and they will not bolt on. The bolt holes don't line up nor do the intake runners line up between engines.

The cheapest way to get the effect of Pineapple sleeves is to just put an epoxy radius at the back. As long as they are clean, it works fine. I've been running this setup for several years now. Do not use JB Weld. That crap has no business even existing yet alone in your car. When it gets warm, it gets soft and has a tendency to deform. It will come apart on you. JB Weld is marketing bs. The epoxy radius is quick, cheap, and does exactly what the Pineapple sleeves do. You are no more likely to have an issue this way than you are with the Pineapple sleeves.

I remember seeing a post a while back where the guy secured the sleeved by drilling and tapping a hole in the inserts and securing them with a set screw put in through the back of the sleeve. I've also seen pics of an engine destroyed by the sleeves coming loose and causing the rod to be ingested into the engine, it was very, very, very ugly. The rotors, housings and end plates were destroyed. I wouldn't want to risk it for a part that may not actually make any horsepower (probably only 1-3 hp max).
