hey guys Im planning a custom 13b na for my SA 1st gen rx7. it also gonna be carbureated since I prefer carb over fuel injection (my .02). so I was thinking turbo 2 rotor housing and plates with NA rotors, gsl-se front cover, side draft intake with a weber 45DCOE, and custom exhaust, and it will also be Street Ported. trans will be a turbo2 trans and differential will be a ford 8 inch. any suggestion will be greatly appreciated. I was going for more of a little more torque since horse power won't be a problem from rotary's lol

 

You are on the right path. my car is a 85 gs with a 13b, t2 center iron 6 port end irons street ported, high compression rotors, side draft dellarto, racing beat two to one header with 2 and one half pipe to rb power pulse muffler. Did gsl-se full suspension swap, love driving it, it is my daily. you will really enjoy a nice build like mine. Keep us posted on the progress.

 

wouldn't go weber 45, at least a 48... If you go street ported, go with a down-draft weber 48 IDA or worst things worst, a Holley 600

 

that has the makings of a fun car! i would go for a bigger carb too, 45 will work, but if you can find a 48 or 50, do it.

on an NA the 8 rear is not really needed, unless you're racing it, i'd do that last, or just skip it

 

thanks for the suggestion guys. really appreciate the compliment also! gonna write some of this down and put Irvin my build journal

 

Good luck!
