I am thinking about doing a forged 346 or a forged 408 so I would either have max 450rwhp or max 550rwhp n/a. If I added a 200 shot on it, what would I need to upgrade? Would I need to upgrade the fuel system for it n/a>

 

You will defintly need to upgrade the fuel system.A single intank walboro would support the motor but not the spray and motor.For the spray you could go two ways.You could run the racetronix set up.It sells for 249.00 and will supply both the nitrous and motor.Or you could put the single intank in it and look into our dedicated fuel system.This is a complete plug and play system.It comes with everything from the tank to the hoses.This will insure that you have plenty fuel system for now and later.They sell for around 699.00.
