Fuel pressure?
After installing the 60lb injectors is anyone seeing the need for pressurizing their fuel lines further? I was thinking about getting a pressure riser kit. Suggestions?

60lb injectors should be good to at least 350whp with the stock pump - probably 375whp. They are very, very stout injectors, so I don't really see the point to messing with the fuel pump to get more pressure. I think you'll have so many other parts breaking at that point you should save your money for those

The traditional "rising rate" pressure regulator cannot be used on the LSJ without extensive modifications. (adding additional fuel line/s)
The LSJ uses a "returnless" fuel system and the pressure regulator is actually inside the fuel tank. The 60 pounders even at MINIMUM stock fuel pressures of 50psi will still support over 350 HP (using 0.6 BSFC and a maximum of 80% IDC) When operating at 60 psi (as most of them do) you're good to at least 375 HP.
Are you already modded to these levels??
