what are your guys opinions on Bridgeporting? When I have my engine apart I would at least like a mild street port, but might throw out the cash for a bridgeport if it doesn't make the car too undriveable. To make it work right I'm thinking you would need bigger injectors, fuel pump,.... what else? Just thinking about it, testing out my options. Thanks.

It is the addition of an extra port. Check out the Mazdatrix faq, they have some good pictures. bridgeport

You mean the whole job done, intake and exhaust porting plus the bridgeporting. But I'd probably go for standard street intake and exhaust porting.
Do we have to upgrade the exhaust system for taking advantage of porting? How much without the bridgeporting?

bridgeporting adds gobs of power, but they are more prone to break because the apex seals have more distance to travel on the ports. Sometimes they can fall in, thats the most common problem i have heard with them, and the idle is a little rough. You would most likely need a bigger fuel system. why not just get a mega streetport? its just a huge version of a streetport. thats what id do. I don't think bridgeported engines last long than 30k. and hell if your going bridgeport go full bridgeport.

It means I'd need to have higher flow injectors and fuel pump. It has 460cc secondary injectors (NA) supposedly so if I'd put higher flow injectors in, would I need to upgrade the ECU then? ???
And what about the exhaust system afterwards?

When you cut across the water seal groove you should fill the surrounding water passages with a high temperature epoxy to keep water from flowing through that area.
You would really need a standalone ECU for a bridgeported motor. You'll gain your power up high, but unless you build the motor to handle revs consistently above 9K you won't be able to enjoy all of the benefits.
