man i posted this and forgot all about it. Yea the small Pport with porting on the side plates is what I was talking about. I have heard of people doing street ported, half bridged, full bridged and J bridged. I was thinking about going judge ito street port and semi Pport housings to give my car good power but still keeeping it drivable on the streets if I have to use it as a DD later on down the road.

Do you have any pictures of what you are describing. I think my mind pictures it correctly, but nothing like seeing the real thing. Thank you in advance. Brad |
I've always wondered why nobody ever made a semi-p port. I just never saw any, but they've existed all the while.
What about putting S5 13B housings into a RENESIS, porting as described in here, and using 6 exhaust ports too? The header would be easy to make, starting with a RENESIS header. |
I am getting ready to build my semi p-port and ran across this thread. I was thinking about how much of a pain it is to machine a piece of tubing that fit the exact size of the hole you just cut and then matching the contour of the inside of the rotor housing on the tubing. Why couldn't you fill the coolant passage completely with epoxy and then bore your port in the housing? You already have a flat place on the outside of the rotor housing for a gasket to seal against.

That port work is what most people call a "semi-Pport". Almost all the low seven second cars from Puerto Rico are running that port. It is a tiny Pport but you have to remember that all the side ports are also utilized and as with that picture the side ports are also bridgeported. This style of porting combined with a Borg Warner S400 80mm turbo are producing well close to 1000rwhp. http://www.ausrotary.com/viewtopic.php?t=46604 If you follow this link and look at the top 10 worlds fastest 13b powered cars almost all those in that list are running a "semi-Pport". Out of the top ten list only one car is not from Puerto Rico and that would be Abel Ibarra. Here some shots of the semi-Pport manifold.
I wish I could get my hands on one of this , I have one like it but its not the semi-pp one . If you know where to get one let me know , where you found this pics from ? |
