i have a 85 gs 12a and this car is going to be a street/Strip car and a weekend car. but im not really to sure which port i should consider doing.i was thinking a bridge but im afraid a brige might be too much. if i could get some opinions that would be great.

 

use a large street port. my current half bridge port is nice but sucks to drive in traffic

 

is that like a what 20% hp gain

 

bump

 

A half bridge will be modestly more powerful on the midrange,but good for quite a bit up top......Id guess 40 or so HP at the peak?(which is 40% over a stock 12A,provided the right mods accompany it)

A streetport can be anything you want it to be,it all depends on how far you go.A mild streetport is little more than cleaning up the rough edges and castings.Whereas a super wild streetport can brap and be as hard to drive as some bridgeports.
The half bridge,while a comprimise in some regards,is designed to offer the best of both worlds......the lowend and idle quality of a street,but some of the topend kick of a full bridge.

 

ok thanks
what is the life span for a bidge port around anyways

 

It all depends on how you build and take care of your motor
