i am looking into buying a repu with a 13b street port in it and i have a problem. There is a 13b from a rx7 and it has a weber carb and no fuel injection pieces. The coil wiring is messed up and i was wondering if somebody had a wiring diagram from a 13b modified to work on a carbed setup. I dont know if it has a RX7 harness in it or if it has the stock repu harness, but if somebody could hook me up with a general direction of were to get one that would be great.



Sorry if i posted in wrong section i just didnt see a tech topic for this sort of thing.

The '81-85 distributors are the same between the 12As and 13Bs. They are excellent distributors for swaps because they're electronic and don't require an ECU. Wiring would be as per the factory manual for those RX-7s (I don't have it handy). The one big recommendation is to upgrade to direct-fire using an MSD 6A and two high-performance coils (or use a single 2nd gen coil) - it's a relatively easy upgrade once you get the stock distributor wired up.

It already has two msd blaster coils but the entire harness is screwed up and i was just gonna end up splicing in a whole new one so i need a wiring diagram to atleast get me started.

get a haynes manual for a first gen 7. that should help you out alot.
