Hey guys, I recently bought a 180sx with an Rb20 in it and have discovered the cra has many mods the previous owner did not mention or know about, one of them being a very large bosch fuel pump and I am now wondering if the injectors have been changed..
Do stock Rb20 injectors have a red "collar" (I'm guessing thats what its called) or another technical term.. the bit where the plug goes in.
any help will be muchly appreciated..
