Zac,
Unisia JECS manufactures the Bosch L tronic EFI system in Japan under license from Bosch. There is a company profile here http://www.teleparc.com/tms/hall/east/unijex/unijex-e.htm
 
 
Downdraft jets for a L20B would be much the same as DCOE i.e. around 1.4 - 1.75 mm. Have a look at the Canberra 1600 with a cute FJ20DET in this months Fast 4's. On page 36 there is a pic of a Bosch EFI system. What it sounds like you have is the JECS version from the Bluebird 910 SSST.

List, is JECS a nissan thing?
I have something which I think is a fuel pressure regulator. It has JECS and some part number written on it.
It has a vacuum hose plug on the top and two fuel hose plugs on the bottom. I am assuming that is what these plugs are for.
Is this part identifiable through it's part number?
 
Also, what are good downdraught weber settings for an L20b? I got the jets out of my DMTT and would like to compare numbers - check how close they are to what I need!
 
thanks in advance!
zac
