Larger Side Feed Injectors for TB45 550cc

Post by GQTRBO »

Does anyone know where I can get bigger side feed injectors to suit a GU Patrol 4.5lt. Have turboed but now need bigger injectors. Have looked at RB25et Skyline but Oring size is too small.

Don't think you can get them. I had same drama, i had to make custom fuel rail and use siemens 660cc injectors, you will also need high pressure fuel pump and a fuel reg....
Good motor to turbo though i got over 200kw at wheels on 6 pound, drives great and never over heats!!!!!!!!!

Who did your Fuel Rail? I've already done the fuel pump and Reg. They are drilling and high flowing mine at the moment and think they can get 60% more out of them. I think that will bring them up to 450-500CC. What turbo did you use, computer etc?
