Well a little bigger then what you need but still an option.
I have a set of Precision Turbo and Engine 50lb injectors. The were in my car for about 4 to 500 miles. I wanted to get into fuel injection slowley and am now needing BIGGER injectors for my new set up.
Here is the link for part number 041-0500.

Paid $800 and if they will work for you you can have for $400. I have original bill and case they came in.
Let me know if I can help.
