ok so i own a 74 dodge charger sorry no rotary yet but i wanta buy a fd in like a year or two and i wanta take my time and do the research..lately ive been reading about tuning, supporting mods, single vs twin etc. My question is what exactly is a streetport and a bridgeport? which one is better for a daily driver? price comparison? are there any templates or threads i can read on the two etc. I head that streetport is better for low end power so its best for a street car and a bridgeport is better for top end and better for racing if thats the case why do i see so many bridgeported rx7s? my goal in the next 2-3 years is to build myself a reliable fd with around 400hp using a gt35r becuase of spooling capabilities. i prefer something quick with good low end power. with my charger and its 440 bb it got plenty of get up but i always wanted a fd so if u can help explain to me the difference between a streetport and bridgeport that would be helpful....

thanks man

 

since you want a gt35, and 400hp, that basically means a streetport.

gt35 is a great quick spooling street turbo. 400hp is no problem. bridgeport is for people who are looking for more than 600hp....

 

ok rite now im learning more about porting and what it does for you..and im trying to figure out why they call it bridgeport and streetport? and what is a pineapple port?

 

A bridgeport has a eyebrow for the corner seal to pass over while allowing more air to be pulled into the motor from the other side of the corner seal. A streetport advances the port timing which moves the torque curve further up the rpm range.

Pretty much, you want to make the ports on the motor go from
STOCK:



Please keep in mind, you don't want your port to look EXACTLY like this as this one is what I would call "the lean". Notice at the top of the port, instead of being ported all the way to the back of the iron, its got a little lean coming into the combustion chamber. As far as I'm concerned, for the time you'll spend doing it, this does nothing but make your motor sound mean.
STREETPORT:


In a bridgeport, the motor is made for racing. Your idle is going to be roughly around 1500-2000 depending on the size of the bridge. Keep in mind your driveability and gas mileage will be hindered depeding on the size of the port.
BRIDGEPORT:

 

omg thanks dude i understand it so much better and i want my car to sound mean haha but streetport seems the way to go i wanta good torque curve and i can always spray if i want more power out the hole. would u consider buying a fd for your first rotary cuz i got the cash cuz of all the free money from scholarships to go to coollege but i dk for my first project to get a fd but its just so sexy

 

I would save my money for food and clothes if I lived in the US right now.

 

The fd is a great car, and can be a great commuter car if you take care of it and do all the precautionary maintenance. Let me know when you are serious about looking for one, I think I can help you find a couple

 

man thanks bro wuts ur number man ? well with the scholarship money im getting and the money i got saved up plus the money im making this summer i should have over 12k to buy an rx7 by august-september, last summer i almost bought a n/a fc but it wouldnt turn over so i ran away from a good deal and the old lady only wanted 500 to but now im motivated to get a fd no matter what cuz its always been my dream car and if i have to i will sell my charger but its worth it
