what are some benefit of a half bridge port?
how long does a full bridge port 13b motor last?
how reliable is a full bridge port motor?
what kind of parts would i need to have a properly working bridge port motor?

 

no, no, no, and... no.

 

More air into the motor and reliability depends on many things from proper porting(tracing seal paths, bridge thickness etc), tune, what the motor is used for(race engine singing in the 10k range will generally cause more wear than ur typical street use motor.

 

damm ok so i guess ill just go wit a street port btw im planning on a 13b powered ae86 an im looking to get about 170 to 180 to the wheels

 

A turbo 4AG would be much smarter for that chassis and horsepower level.

 

J-spec 13BT from a reputable seller and turn the boost to 10 PSI. Easy 200 HP.
