Default lq4 questions

so I am building a 6l twin turbo
read lots of posts on here about various things - and found some things that seem to be missing - lots of posts but no answers

first one is what fuel rails will fit the truck injectors ie will aftermarket LS1-Ls6 physically fit the tops of the truck injectors - I ask because one can buy ls1 rails for like $58 and truck rails tend to be in the hundreds

does anyone know if the truck regulator on the fuel rail can be modified to be 3/8 line at source not just an add on to the 5/16 line

does anyone know if the truck rail regulator can be modified to produce more pressure akin to what they used to do with LT! or Mustang regulators by dimpling the case to put pressure on the internal spring

many posts on the various types of injectors from ev1 through 6 and ascar type injectors etc and no idea from pics what that means or the original application

what type is the truck injector, and what type is the car injector, and what others can be readily used on the truck intake if one spaces the fuel rail accordingly.

are the injector wire adapters ok to use or should one solder in the correct harness ends

thanks
Ken

The aftermarket rails can be use but you have to fabricate brackets to hold them. Just use small spacers with the taller injectors.
Not sure what truck rail you have that has 5/16" unless you are referring to the return which in that case what power level are you seeking?
Not sure about modifying the stock regulator but you can change the rail to the return less style and add a regulator with reference.
Injectors should be Multitec style. Don't think there are larger ones with that style plug but I might be wrong about that.
Using the adapters is fine, unless you are going for clean look then change the connector.

What kind of power are you planning on making?

If its below ~750whp, your first 3 questions are irrelevant.
