going from 850cc prims to 550-650cc
So I am having problems with these 850 injectors.I would like to go back to 550 or even a 650cc but the thing is I bought a whole fuel systems the came with the kgparts fuel rails. The problem is that I need to get the aluminium rings out of the engine block ..but damn those lil fu..kers are hard to get out. I dont want to drill them out due because of debris that might get in the block. So I may be stuck with a top feed injector. Now I would like to find a 550cc or 650cc top feed injector to fit into the primary fuel rail. Any suggestions ? thx

kru510 since your PIM voltage is not changing when you start the car (staying at 2.6v), your map sensor is not adjusting for vacuum. This means it's just dumping fuel. The ecu thinks it's at 0 boost at all times. This also means it's not adding enough fuel under boost. Once you get your map sensor sorted out, your 850's will idle much leaner and you will stop flooding the engine. You will also probably need to raise the cranking ms back to where it was.
