If your stock injectors are fine and your only going to do the nozzles,and looking for 90hp I would call Jim at extrude hone.For large increases I would go with exergy.
Exergy will be a little leary about you sending just your tips. The want to flow and balance the injectors to match the tips they put on them. You'll be looking at around 1K.

Only thing they were leery about when I talked to Greg, was the mileage and known history of the tips/bodies. True, they would prefer you send them your complete injectors, but He had no problem with selling me just new Bosch nozzles honed to what I want. Ended up having them hone my stock tips. Talked with him for like 45 minutes (more like he talked, I listened), very knowledgeable guy.
