Needle and jet profile for stock-ish 4g54

Post by barana »

I've kicked off a new project in my 91 Paj.
Something special(I think)
I'm installing a commodore ecu to run two dfi coilpacks on the 2.6 with the dizzy delete,
And I've got something special for the Carby. A motorcraft Variable Venturi 7200 twin barrel.
Ford never offered (that I'm aware )needle and jet specs, so I'll be setting it up myself.I have a fuel mapping program here so I can start somewhere for the fuelling. But until I get a wideband 02
Sensor, I won't be able to start.

So here's my question can anyone tell me needle and jet sizes they use for a stock na 2.6? can be anything from su to strommy to Hitachi to motorbike carbies single to quads as I can start from your figures with the fuel mapper.
Thanks, I3arana.

Thanks for the kind words and welcomes.

I'm currently acquainting myself with this Site, and hope to be posting a pic, here-or-there in this thread, whenever I can.
