These are at (least in theory) the perfect nozzles for a hot rod 4JG1 Standard 4JG1 nozzles being something tiny like 4x0.17 (don't quote me on that, I just remember them being tiny) Hopefully they fit a set of narrow body 4JB1 injectors I have coming ,,, Def looking forward to the water meth! I've got bits coming from ProMeth (great selection!)in the states, have readied manifold for port injection, 4 x 95cc nozzles, For a total flow of 380cc/min @ 100 psi, or approx 700cc/min @ 200psi. Will test on dyno to see how much is needed
