You can send in your injectors to Mepeh injectors or buy a rebuild kit from them.
You can place an order here
Lots of good reviews here
I got a set of s50/m50 green top 17lb injectors for free.
Only thing wrong with them was one missing pintle cap.
I contacted Dimitry owner of Mepeh injection, he was very polite I met him at his house to pick up a rebuild kit for my injectors. He offered to install my injectors on his machine to flow match them and test them out.
We ran them at 3 bar at 7k rpm
and up to 4 bar and 7k rpm they passed all the test.
Also ran a draining cycle and they all where very close to one another.
Cutting the pintle caps off
Old injector filters vs new high flow filters.
Injectors completely disassembled and cleaned.
Rebuild kit plus a few spares not in the picture.
6 high flow filters
6 upper O rings
6 spacers
6 lower O rings
6 pintle caps
Filter extraction tool not in the picture
Assembled just need to put some Vaseline on the o rings
Installed with a new 3.0 bar fuel pressure regulator
Installed
Unplug negative battery terminal for 30
Minutes and it will help the ecu clear out and help calibrate to the new injectors on the first test drive.
I documented some of the injector rebuild process for those interested.
3 short clips but it may help someone tackle this job.
