93camarochrisz28

what type should i get i want to be around 350 360 rwhp and then i will be putting a n20 on it to get around 420 430 i hope lol any help would be good i have no idea what to get

The stock fuel rails will work fine with 350-360 rwHP. What type of nitrous system will you be adding? A wet system will not put any more fuel through the rails, and a dry system will typically increase the fuel flow by increasing the pressure.

i was told the best for me would be a wet setup

Then you don't need anything other than the stock rails. The configuration of the 93 fuel rails is unique, due to the batch fired injectors.

as for the 350-360 rwhp is that just the 93's or all lt1's?

what you mean batch fired injectors ??

Injuneer

You 93 fires all four injectors in one bank of the engine at once. The injectors are not sequenced to the firing of the cylinders. They just fire once for each crank revolution. The 94 and later LT1's use full sequential injection. Each injector is fired in sequence, based on the cam position - that's what the low resolution pulse pattern of the Opti is there for - to identify the TDC position of each individual cylinder.

With batch fire, and four injectors firing at the same time, there will be a slight drop in the pressure as the injectors fire, and then it will recover when they close. Sequential fire provides a more uniform fuel demand and results in a more uniform fuel pressure.

One thing I did to minimize pressure variations between the inlet (#8) and outlet (#7) ends of the rails was to split the fuel supply and feed the back of both rails, taking the return off the diagonal cross-over pipe at the front of the rails. That puts the 94-97 rail configuration in parallel, rather than in series, and minimizes the differences in pressure from the first injector to the last. But my system supplies 800 flywheel HP, including a 300HP dry shot (dual 205 LPH pumps, 78# injectors, 58psi fuel pressure). I don't think the 93 rails can be "split" like that, because of the internal pipes, but it may be possible.

I've seen the stock rails support over 1,125HP running in the parallel configuration.
