I have to go through a defect inspection which means I need a stock rail to pass, I have an r34 neo motor with an r33 intake on it currently, what 'stock' fuel rail out of rb20/25s will give me the best injector options and bolt in without modification? I was planning to change this as the stupid alloy rail and aftermarket reg I have now sucks and I don't like it (came with the car) plus it will never pass an inspection so this has sped up my plans. The car has been legally registered with the rb25 so this is not an issue.
I've done a bit of a search but not really found any definite answer, I would be looking to put in 550 to 700cc injectors, preferably ones with a better than stock spray pattern, if a resistor pack is needed that is not an issue. I'm pretty sure the r33 intake uses a side mount fuel rail standard so would like to keep it looking stock.
What are my options?
edit: Also I doubt this but are there any distinguishing features on stock injectors, eg colour etc on rb25s? I don't know what they look like, will try and paint whatever I get a similar colour.
