I'm contemplating doing a bridge port on my s5, now keep in mind when responding that i am located in Ontario Canada.
With a bridge port on this n/a, what kind of upper rpm horsepower can i expect? (i dont wanna hear anything about power loss, because when i want the power, im gonna stay in the high revs) is mazdees the best place to take it? what kind of cost range am i looking at? and what do i need to send to them? ie. pull the engine and bring that to them or disassemble the engin e and bring only the components which need to be ported? thanks in advance for your help

trying to understand here.. Are you rebuilding a blown the motor or are you tearing apart a good running motor simply to bport it?

 

Personally, i've never seen a bridge port motor last more than 10K miles before puking...

 

Thats because they normally dont last much above 10,000 miles. If reliability is even a MINOR factor in your rebuild, then a B-Port isnt for you.
