im just looking for a quick answer here... I have the racing beat 13b 4 port bridgeport template. can i use the bridge port on it on the 6 port plates? im going to adjust the length of to work for the 6th port only. but wanted to use it in reference of how wide and how close to the jacket it can be...



or if someone can explain on how to determin where i can and cant put the bridge, as in..how many MM from the water jacket area. or if i go large enough into the water jacket area. what has to be done so it doasnt cause a problem.



i also have the pineapple racing 6 port streepport template and will be using this also. im combing the both...

after reading what i wrote it seemed a little confusing. let me ask my questions a better way...



This is a motor being used for daily driving and occasional track use. its an s5 6 port. I have the racing beat 13b 4 port bridge template. and the pineapple racing 6 port street port template. only the Auxillary port will be bridged. the pineapple racing street port will be used on the rest of the ports.



1. How can i trace the line the corner seal rides along to make sure i dont port to where the motor eats the corner seal?



2. How many MM is enough for the water jacket to be safe when doing a bridge?



3. If i decided to port into the water jacket area (large bridge or J-bridge), do i just cut the water jacket where it meets the port and fill the surrounding area with epoxy?



4. would it be better to bridge both the 5th and 6th ports? if not, should i bridge the 5th or 6th port?



5. should i leave the 6th port sleeves in wired open, or remove them completely and use JB weld to smooth the area where it goes past the opening on the port face to the flat area? (JB weld has a 500 degree rating, this should be enough for that area?)
