I'm planning to upgrade my 50 shot to a 75 shot on my ss lude. What do I need? I've read that I need...ignition, spark plug wires, fuel pressure regulator, retarded ignition...I already have colder plugs. Is this all that I need or more than enough? I don't wanna say that I just want the bare essentials but I don't wanna spend too much money to upgrade. I guess I wanna get everything I need to keep from running lean and feel safe whenever spraying...thanks in advance for any replies

 

Are those your only mods on the engine?
Better start thinking about cams, pistons, and rods.
If your running stock internals with a 75 shot, it's not a matter of 'if', it's a matter of 'when'.

If you properly tune your car. The 5th gen can take a 100 shot. mine friend is going on a 125 shot for 2 years now and all he has is I/H/E VAFC and crane ignition. I'm not to sure about automatic ludes though. The only problem I have with nitrous is that as much money as you spend filling that bottle you might as well just save for a supercharger/turbo.
