I'm getting a 13B 4 port built for my 80 right hand drive. Getting it street ported also. Has anyone here done this conversion? I need a list of stuff i will need. Is the heavy duty clutch/pressure plate the same? Also gonna run a sidedraft carb and headers.

Can anyone give me some good info.

Thanks, Steve

 

the conversion is not too popular.. but i think its better than having 6 ports... 13b 4 port is done by either using 12a or turbo II side housings.. if u you use 12a side housings i believe u have to use 12a mounts... street port sounds good.. but i have a 85 gsl 12a bridge ported on the high end(half bridge) and a racing beat intake with a holley 650 on top.. rb header and exhaust.. no cats... and the car is incredible.. shifting at 10 grand
