Yeah im using the 2JZ ecu but it came from an Aristo not a JZA80.
Ive put a JZA80 fuel pump in the tank but its connected to the stock GA70 wiring.
GA70 pump would have been fine for the moment but id rather not have to worry about it. That and I got the JZA80 fuel pump for $50.
sixworks website was down last time I checked. I email the guys there and they told me they shut down the site after dispuits with their host and just hadnt had time to find a new host.
