I am doing a 3.4 swap and the injectors from the donor engine have a crack in one of them. I want to replace them but want to know where to buy a reputable set. Ebay has chinesium for $50 for a set, I'm sure those will work great said no one ever. Who do you trust for a good set?

After trying several different injectors, this is what I ended up with that worked satisfactorily in my 3.4 swap. From Motor Man Fuel Injectors. Also check with CS Performance Injectors. I have successfully been running these injectors in my 3.4 since 2018, first on the stock 87 ECM and now on the 7730 ECM conversion.

Bosch EV1 Fuel Injector
Jetronic port / 4 hole nozzle
Flow rates @ 43.5 psi / 3 bar
16.76 lb per hour (My Note: 17# rated injectors flow at approximately 16.666 lb/hr at 3 bar or 43.5 psi. See calculator chart below)
126.5 G per min. (N-Heptane)
176.1 cc per min
15.90 Ohm resistance
Note these numbers. Though the same Bosch part number I originally listed, the BMW part number has changed. This injector is for the BMW M3.
Bosch Part # 0280150415
BMW part # 13641730060

Nice, bought a set. Tired of buying parts, want to keep putting parts on to hopefully drive this pile someday.
