4 Port FI 13B?
Can it be done? What kind of power can I expect? My motor is dead, needs a new rotor, and housing. So I am curious because I am sick of dicking with my 5/6 ports/.

Oh dear....
The GSL-SE 13B was 6 port.
Yes, you can certainly run a 4 port NA engine, and the stock ECU will deal with it. In fact, if you are planning on doing some aggressive porting, you should start with a TII (thus 4 port) block, and simply swap in the S5 NA rotors. You now have nice clean exhaust ports (no diffusers) to start your porting on, and the TII irons have lots of extra metal behind the ports so you can get as aggressive as you want. Now simply port your NA intake to match, and you have a great little ported engine...
