Would a jap fuel rail work on a aus 3sge

Why not just plug the hole in the fuel rail where the fuel line for the CSI connects to???

"I know the csi runs off a timing switch not controlled by the ecu"
 
I am no expert, but going by the Gen2 3SGE EFI schematic (see pic),  that may not be correct.
 
However as suggested, you may be able to get away with blocking the fuel rail port and taping up the connector.
 

So blocking the rail didnt work. Just kept pushing the bolt out no matter what washer I had, (think port may be cross threaded no idea how it happened but I took it out and bolted it back in perfectly.. I spent numerous years working on bikes with my dad and doing some local work with a mechanic so I do know how to put a bolt in without stripping the thread, even tried a different bolt still wouldn't work.

So will a Japanese rail work? Will it all match up mounting points etc
Head location? Will it be a straight swap?

If you can get the banjo back on, you could get its outlet welded up and that will be a good seal.
 
Or if the thread in the rail is stuffed, you could retap a new thread and block it off. 
 
Cheers
 

hey, found the jdm rail. sorry for the delay, thought you'd have success just blocking up the port so didn't bother last couple days looking.
 
here it is. the inj's will stay attached to the fuel rail when it comes off as the o rings hold them quite snug. they just have "cushions" that seal them to the head.
 
pm me your address and i'll express post it tomorrow.
