I have seen people list gutted 6-ports as a mod on NA's. I imagine this involves removing the actuator rods and leaving just the sleeve, but how do you secure it so it doesn't rotate?



I can see how this would increase flow as opposed to just wiring them open, but how much does it really help?



And no I don't care about not having low-end, I have driven it with them wired open and it has enough.



Thanks for any input.

I drove around a while with the 6 ports wired open. Car will not hold idle with the AC on!

no AC, no PS, no problem.

I would just leave the sleaves out. If your engine was apart it would be fairly easy to epoxy a smooth transition at the end of the ports like in the Terrentine video. But with the engine together it would be somewhat difficult. If you really wanted to run with the pineapple style sleeves I would probably just wire them open again. But if your not worried about low end, just leave them out. I ran without sleeves for 6 months and then put the sleeves back in with the pineaplle inserts. I noticed better low end at, least it was a lot smoother. But up top it felt the same as with the sleeves removed.
