Cheers for the info mate. I knew that there wasn't much to be gained from a S-port but if the engine was going to be apart thought I might aswell just port it. And would a deburring/cleaning the runners so there is a smooth transition, or is this another case of just the old 13b was like that. And that is a good thing to think about in regards to the AP bc I was thinking of a turbo kit down the road, small amount of boost tho no more the 8 psi I might even run only 4 psi bc wen I turbo it I will be running the 10:1 cr rotars. Ill be honest tho idk how rotarys do with high comp and turbo, but I know piston engine DON'T like to be boosted wen compression is high. Is there a tread on hear by chance explaining high compression turbo setups and wat the possible repercussions are, posting a link would be great but all u have to say is yes or no and ill search it if there is. I know on piston engines a few things can happen with high comp turno setups, but the biggest one is snapping a conecting rod. So would to much boost on a 10:1cr rotary blow seals/crack a housing or anything like that, or would it just take it.

Plus the main reason I want to do a high comp turbo setup is I was talking to a guy I work with who owned an 8, he said the only reason they have a 10grand redline is bc over that an it cannot get enough air to continue to make power. He said if u put on a TD04 with mild boost you could raise the rpm. is this statement true, so I'm asking the experts(u guys)now lol.
