Message	So, I finally swapped my TT engine, and it runs. But, i have 740cc injectors (I have no idea why I went so big), and the engine is flooding. So, I was told I need to go down to 555's. Now, I have a set of 4 used, JECS 550 injectors. Im thinking of having them checked to make sure they work fine, and then just buying 2 new ones. Questions are.... do I have to get the same company injectors ? Can I get Deatschwerk or Nismo injectors ? Will it matter if the 4 are old but still work, and 2 are new ? Anyone want to trade 740 injectors for some 555's ? =)
